( etwork ddress ranslation) A standard that allows an organization to present itself to the Internet with far fewer IP addresses than there are nodes on its internal network. The NAT technology, which is typically implemented in cable, DSL and ISDN routers, converts private IP addresses to one or more public IP addresses for the Internet.
Network Access Translation. A hardware device currently being developed and used to extend the Internet addresses already in use.
A process that converts private IP addresses on a LAN to the proxy server's IP address before a data packet is sent over the Internet.
A way to convert private IP addresses to publicly routable Internet Addresses.
Network Addressing Translation – Technique to map inner IP numbers to a single external Public IP address. Evolved due to the relative scarcity of IP addresses.
Network Address Translation. A network capability that enables multiple of computers to dynamically share a single incoming IP address from a dial-up, cable or DSL connection. NAT takes a single incoming public IP address and translates it to a new private IP address for each client on the network. (See DHCP, IP address). close
An Internet standard that enables a local-area network (LAN) to use one set of IP addresses for internal traffic and a second set of addresses for external traffic. A NAT box located where the LAN meets the Internet makes all necessary IP address translations. NAT serves three main purposes: 1) Provides a type of firewall by hiding internal IP addresses. 2) Enables a company to use more internal IP addresses. Since they're used internally only, there's no possibility of conflict with IP addresses used by other companies and organizations. 3) Allows a company to combine multiple ISDN connections into a single Internet connection.
Network Address Translation. Enables a local area network to use one set of IP addresses for internal traffic and a second set of IP addresses for external traffic.
Network Address Translation. The translation of an Internet Protocol address (IP address) used within one network to a different IP address known within another network. One network is designated the internal network and it appears as one entity to the outside world. In the case of wireless LANs with an outside Internet connection, the NAT capability of Internet-sharing software allows the sharing of one Internet connection among all the wireless PCs connected.

Stands for "Network Address Translation." NAT translates the IP addresses of ...
Network Address Translation is the ability to show one IP address to the world while concealing the IP addresses of the other computers on the network. A router usually performs this function.
network address translation. A protocol that allows a network with private addresses to access information on the Internet through an IP translation process. With NAT, you can configure your home network or small office network to share a single connection to the Internet.
Stands for Network Address Translation. This is a method of allowing multiple computers to connect to the internet using the single IP address supplied to you by your ISP. NAT can be carried out using software, but is more commonly a feature of routers.
A hardware device currently being developed and used to extend the Internet addresses already in use. NAT has been suggested as an alternative to adopting IPv6 (IPng). It allows duplicate IP addresses to be used within a corporation and unique addresses outside.
Network Address Translation. The translation from a private IP address to a public IP address or vice versa. NAT was designed to overcome the lack of IP (version 4) addresses and to represent a private network as a single entity in a public network like Internet. Also see IPv6.
Network Address Translator. A network capability that allows for the dynamic reuse of a single IP address for all PCs on a network.
A method used typically by routers, which essentially masks or "hides" all the internal network computers' IP addresses form the outside world behind a single public IP address. NAT both protects the network and allows sharing the Internet connection among several computers on the network.
Network Address Translation. This allows an organisation to present itself to the Internet with far fewer IP addresses than there are nodes on its internal network. The NAT technology, which is typically implemented in a router, converts the private IP addresses (such as in the 10.0.0.0 range) of the node on the internal private network to one IP address or of several IP addresses for the public Internet. It changes the packet headers to the new address and keeps track of each session, so that when the packets come back from the Internet, it performs the reverse conversion to the IP address of the client machine. NAT also serves as a firewall by keeping internal addresses hidden from the outside world.
Network Address Translation. A process that modifies either the source IP address or destination IP address of an IP packet.
Network Address Translation. Hides the IP addresses of client stations in an internal network by presenting one IP address to the outside world. Performs the translation back and forth.
Network Address Translation is an advanced feature of certain routers. If NAT is enabled, the control information in the header will actually be recorded to a table in memory, then changed so that it will appear as if the packet was sent from the gateway machine. When a packet arrives at the router, it can refer to the table to determine who originally sent the packet so it may be routed back to the right computer. Otherwise the packet will be discarded.
network address translation. An Internet Protocol (IP) translation process that allows a network with private addresses to access information on the Internet.
Network Address Translation. A broadband configuration that offers extra security and enables more than one computer to use a single IP address (your location on the internet).
Network Address Translation - A program or piece of hardware that converts the IP address from a private address to a public address real time. This allows multiple users to share a single public IP address. It also prevents access to these users from the outside without special configurations. NAT is used in home networks and corporations to allow multiple PCs to access the internet via T-1, ADSL, SDSL or Cable Modem.
NAT stands for Network Address Translation. This is a configuration that provides extra security on the Internet.
network address translation. The ability of a device such as a router to convert IP addresses from one network to those of another.
A NAT is logically similar to both a proxy and a gateway. The NAT hides the private addresses of the local network from the public address side attached to the Internet. The NAT takes packets from the private network and re-writes them using one of its public IP addresses and sends it onto the public network (Internet). When the response to the packet comes back the NAT takes this inbound packet and redirects it to the private address that originated the traffic. NATs allow large groups of computers to access the Internet through a very small number of IP addresses. Without NAT technology the supply of IP addresses would have run dry in the late 1990's. The Internet Connection Sharing built into Windows 98SE and later is a NAT.
Network Address Translation. A process that lets an entire network connect to a PPP server and appear as a single IP address, thus helping to conceal IP addresses from external hackers and to alleviate address space shortage.
A method that many networks use to extend their IP addressing to support more addresses than they own. The interior network uses one addressing scheme, and the exterior network uses the standard IPv4 Internet addressing. NAT devices can be routers, firewalls, or proxy-servers.
Network Address Translation. A system of translating an IP address used within an internal network to a different IP address used on another, outside network. DSL routers may use NAT (also called "Port Forwarding" or "Virtual Server" on some routers) to direct incoming connections to servers on the local network.
(Network Address Translation) A router that allows you to keep a set of IP addresses for internal use and another set for external use. This increases security by limiting what IP addresses the outside world has access to and allows the same internal IP addresses to be used on different networks.
Network Address Translation. A method for translating internal IP addresses or network addresses into a single globally unique IP address. It permits a nearly unlimited number of users of one class C Network address because global addresses are required only when a user is connected to the Internet. It also serves as a fire wall by keeping individual IP addresses hid-den from the outside world. NAT is configured by defining address pools and specifying whether a port is "Inside" or "Outside". Also see IP.
Pretty much all Broadband routers assign IP Addresses in the form of 192.168.blah.blah or 10.0.blah.blah to local computers. These ranges of IP addresses are reserved for local networks and aren't valid on the wider Internet. NAT is the service performed by the router. The router alters the address headers of the packets to and from the Internet. It assigns it's own unique WAN address to the outgoing packets from local computers, collects the resulting inbound traffic and changes the packet addresses once more so that the incoming traffic is routed to the correct computer on the local network.
is an acronym for Network Address Translation. It is a way of dealing with the relative scarcity of IP addresses by allowing different hosts to have the same IP addresses and then to translate between public and private addresses. Unless that translation is done carefully it will play havoc with FTP which sends IP numbers through the control connection.
Network Address Translation. A technology used in routers and firewalls to translate an Internet address to one or many local (LAN) addresses and vice versa (see diagram).
Network Address Translation is an algorithm that allows multiple local computers to share one external IP address. Routers use NAT to accomplish this very thing. Also, many firewalls use NAT as a basis for security.
Network Address Translation. A NAT allows multiple users on a private network to connect to the internet by masking their individual IP addresses and displaying, generally, one IP address on the internet.
(Network Address Translation) – Is the translation of an IP Address used within one network to a different IP Address known within another network. Typically a company maps its local inside network addresses to one or more global outside IP Addresses and unmaps the global IP Addresses on incoming packets back into local IP addresses. This helps ensure network security since each outgoing or incoming requests must go through a translation process that also provides the opportunity to qualify or authenticate the request or match it to a previous request. NAT also conserves on the number of global IP Addresses that a company needs by letting a company use a single IP Address to communicate with the world. NAT is also a feature of most routers and firewalls. See Also: IP Address, Router, Firewall To top
Network Address Translation. An Internet standard that enables LAN, WAN (Wide Area Network), and MAN networks to use extended IP addresses for internal use by adding an extra number to the IP address. This standard translates internal IP addresses into external IP addresses and vice versa. In doing so, it generates a type of firewall by hiding internal IP addresses.
Network Address Translation The translation of an Internet Protocol address (IP address) used within one network to a different IP address known within another network. One network is designated the inside network and the other is the outside. Typically, a company maps its local inside network addresses to one or more global outside IP addresses and unmaps the global IP addresses on incoming packets back into local IP addresses. This helps ensure security since each outgoing or incoming request must go through a translation process that also offers the opportunity to qualify or authenticate the request or match it to a previous request. NAT also conserves on the number of global IP addresses that a company needs and it lets the company use a single IP address in its communication with the world.
Network Address Translation makes it possible to translate private IP addresses of a LAN into public IP addresses. This makes it possible, for instance, to allow several computers to access the internet via a single IP address provided by the ISP.
Network Address Translation - technique that allows internal network to use private self managed IP addresses but still talk to other Internet systems with real addresses.
Network Address Translation is the translation of an Internet Protocol address (IP address) used within one network to a different IP address known within another network. One network is designated the inside network and the other is the outside. Typically, a company maps its local inside network addresses to one or more global outside IP addresses and unmaps the global IP addresses on incoming packets back into local IP addresses. NAT is included as part of a router and is often part of a corporate firewall.
Network Address Translation. An address translation function used in SKIP where packets passing through a box have their addresses changed (or translated) between sets of addresses to hide internal addresses such that they cannot be used as an attack point. It is also useful on the Internet as you must use registered addresses so no two systems use the same address. However, many internal networks were built without registering their addresses because they were built before the Internet was considered vital to business. Address translation can be used to translate unregistered (that is, illegal) addresses into a smaller set of registered addresses, thus allowing internal systems with unregistered addresses to access systems on the Internet.
Network Address Translation. NAT is the translation of a protocol used within one network to a different protocol known within another network. Return to .
NAT is an acronym for Network Address Translation. It is a commonly used IP translation and mapping technology. NAT acts as an interpreter between two networks. It sits between the Internet and your internal network. The Internet is considered the 'public' side and your home network is considered the 'private' side. When a computer in the private side request data from the public side (the Internet), the NAT device will open a little conduit between your computer and the destination computer. When the public computer returns results from the request, it is passed back through the NAT device to the requesting computer. Using a device or piece of software that implements NAT allows an entire home network to share a single internet connection over a single IP address. A single cable mode, DSL modem, or even 56k modem could connect all the computers in a small internal network to the Internet simultaneously. NAT is built in to the most common Internet Connection Sharing technologies around. Microsoft has built their ICS around it and every Cable/DSL Broadband Router on the market accomplishes its job with NAT.
NAT - Network Address Translation - also called IP masquerade, is a process of translating the source header of IP packets so they will be routable across wide area networks.
Network Address Translation. A software standard which allows a network to appear as a single address on the internet. NAT does the conversion to individual devices on the network.
Network Address Translation. Modification of one or more of the following fields in an IP packet: source IP address, destination IP address, source TCP/UDP port, destination TCP/UDP port.
Short for "Network Address Translation." Hardware or software that allows multiple computers to share a single IP address. Often, NATs are part of another piece of equipment, such as an Airport Base Station or a router.
Network Address Translation An Internet standard allowing a local network to use one public IP address to connect to the Internet and a set of local IP addresses to identify each PC or device in the local network.
As IP addresses became scarcer in the 1990's, Network Address Translation became more popular and is today used virtually everywhere. Using NAT means a large range of IP addresses (usually private) will be translated into a smaller range of public addresses, sometimes only one address. NAT in itself also gives simple firewall functionality as it will work in the same way as setting up a Dynamic State for all outbound traffic.
A means of masking IP addresses on a LAN. It provides each client host with two addresses: one used within the net, and another known outside it. The NAT simply replaces all “real” addresses with masked ones on outbound packets, and masked addresses with real ones on inbound packets. This hides the “identity” of all client hosts from the outside world. NAT can also be used to replace all network addresses with a single masked one, so that each client host has the same apparent IP address outside the network.
etwork ddress ranslation. A networking technology that allows multiple computers to share a single Internet connection. A NAT box is any device running NAT software. It links a LAN to the Internet, essentially "translating" privately-addressed packets into publicly-addressed packets that can be sent back and forth across the Internet. As an added bonus, NAT boxes act like a firewall to computers on the LAN becuase they mask their actual IP addresses.
Network Address Translation. The name given to the process whereby one IP (Internet Protocol) address is mapped (or translated) to another. This generally occurs when a globally valid IP address is mapped to an IP on a private (internal) network. The benefits of this are several. Firstly it becomes possible to connect many machines to the Internet with only a single Static IP address. It also 'hides' the actual addresses of the internal machines, since to the outside world, all the machines share the same IP address - the network looks like a single machine.
see Network Address Translation (NAT)
NAT technology translates IP addresses of a local area network to a different IP address for the Internet.
Network address translation: the translation of an Internet Protocol address used within one network to a different IP address known within another network. For instance, a DSL router has two NIC cards. The external card will have a LISCO (public) IP address. The internal card (connected to your LAN) will have an internal IP address. The router will do NAT to route traffic to the correct computer in your LAN.
Network Address Translation (Converts WAN IP adresses and ports to private LAN IP addresses)
(Network Address Translation). NAT refers to the process of converting the IP addresses used within a private network to Internet IP addresses. Also see Internet IP Address Network
Network Address Translation. Network Address Translation (NAT) allows computers on a private network to access the Internet without requiring their own global (public) Internet address. NAT modifies outgoing network packets so that the return address is a valid Internet host (usually the address of the ePipe itself). Return (incoming) packets have their destination address changed back, and are relayed to the client host, thereby protecting the private addresses from public view.
network address translation. The conversion of a network address that is assigned to a logical unit in one network into an address in an adjacent network. In a firewall, the conversion of secure Internet Protocol (IP) addresses to external registered addresses. This enables communications with external networks but masks the IP addresses that are used inside the firewall.
Network Address Translator (NAT), Network Layer, Non-Repudiation
Network Address Translation. Sometimes referred to as IP Masquerading, a NAT allows the local network to utilize private IP addresses. As information travels to the public IP address, the gateway translates the traffic from the public IP address to the private IP address for the computer that requested the information.
Network Address Translation. A function, typically employed in internet connections, that performs address translation. Or a method by which IP addresses are mapped from one group to another, transparent to end users.
Network Address Translation. NAT is an internet standard protocol that allows multiple computers on a LAN to share an IP on the WAN.
A technique—generally applied by a router—that makes many different IP addresses on an internal network appear to the Internet as a single address, concealing the specifics of the internal network.
Network Address Translation is a means of allowing computers on a LAN to access the WAN while "masquerading" with the IP address of a host with a suitable address and configuration. With Linux this is called "ip-masquerading". Often used to share one public, routable IP address among hosts located on a LAN behind a masquerading proxy where the local addresses are private and non-routable.
(Network Address Translation) - Translation of IP addresses of a local area network to a different IP address for the Internet.
Network Address Translation. The method of converting one IP address to another IP address; primarily used to connect a network which has an internal address space that is on a different standard than another network, such as the Internet.
Network Address Translation is an Internet standard that enables local area networks (LAN) to use one set of IP addresses for internal traffic and a second set of addresses for external traffic.
Acronym for Network Address Translation. The process of converting between IP addresses used within a private network and Internet IP addresses. NAT enables all of the computers on a network to share one IP address.
Network Address Translation is a system that allows each individual computer in your corporate or home network to have an individual IP address inside the network, while sharing a single external IP address. If you are using a cable modem or DSL router and a network, you probably using NAT. For an excellent description of NAT, see How Network Address Translation Works at Marshall Brain's HowStuffWorks.
(Network Address Translation) is a process whereby the machines on a LAN are allocated IP addresses in the reserved range for private networks (192.168.254.x). When a machine requests information from the Internet, gateway equipment (quite often a router) converts the private IP address of the machine into the single real IP address of the gateway and then makes the request for information on behalf of the machine. The gateway keeps track of which internal machine requested which piece of information, and therefore passes the correct response from the Internet back to the correct machine. In this way, all the machines on the LAN will appear to the outside world as if they all have the same IP address. This increases security and saves on the number of public IP addresses that need to be used.
Network Address Translation. A protocol used to provide a mapping between internal IP addresses and external or public IP addresses.
A service provided by most firewalls to a) hide computers from potential hazards and b) to allow more than one computer to share an IP Address.
Abbreviation for "Network Address Translator"] Corporate networks who want to have their own internal network addresses (that may conflict with external Internet address) use a NAT. The NAT intercepts outgoing communications and converts conflicting IP addresses to something that the Internet will be happy with.
Network Address Translation. Used to reduce the number of IP addresses required. Allows a single device, such as a router, to act as an agent between the Internet (or "public network") and a local (or "private") network. This means that only a single, unique IP address is required to represent an entire group of computers.
Network Address Translation - allows a network of computers to present a single IP address to the Internet.
Network Address Translation. A mechanism that provides a mapping (or transformation) of addresses from one network to another. This enables external access of a machine on one LAN that has the same IP address as a machine on another LAN, by mapping the LAN address of the two machines to different external IP addresses.
Network Address Translation. Type of basic firewall that keeps your private IP addresses on the computers in your network masked from other users on the Internet. This makes it harder for unauthorized users or hackers to get to your personal files and data on your computers.
Acronym for Network Address Translation. NAT, as specified in RFC 1631, is an Internet standard that enables a local-area network (LAN) to use one or more IP addresses for internal traffic and a second for external. A network NAT is commonly used by home users to allow multiple computers to easily connect to a broadband connection. NAT is also used to hide Internet network addresses by using the single NAT address. Today there are two different variants of NAT used. NAPT which is short for Network Address Port Translation, and PAT which is short for Port Address Translation.
Network Address Translation. NAT occurs when multiple IP addresses on a private LAN are converted to one public address. This public address is sent out to the Internet. NAT adds a level of security because the IP address for a PC connected to the private LAN is never transmitted to the Internet. NAT also allows xDSL/cable routers to be used with low-cost Internet accounts, where only one TCP/IP address is provided by the Internet service provider. The user may have many private addresses masked by the single address provided by the ISP. NAT prevents denial of service (DoS) from external networks on internal hosts.
Network Address Translation (NAT) is a method of connecting multiple computers to the Internet (or any other IP network) using one IP address. This allows home users and small businesses to connect their network to the Internet cheaply and efficiently.
Network Address Translation. Network Address Translation (NAT) is used to rewrite the contents of the Internet Protocol (IP) packet headers so that all packets appear to come from a real address (the firewall's Internet address).
The NAT functions can map internal IP addresses (illegal or nonroutable/private) to legitimate Internet addresses either many-to -one or one-to-one. Some firewalls and routes offer a type of NAT, oft ... more
(Network Address Translation) – NAT is primarily a security measure that translates a public IP address into private IP addresses that are used within an organization's network. Using a NAT device on the edge of a network protects the individual workstations and servers from malicious hacking. NAT also conserves on the number of global IP addresses that a company needs.
Process whereby one IP Address is translated to another. Generally used to 'map' an internal (private) address to a globally valid (real) IPAddr.
A technique sometimes used so that multiple computers can share a single IP address.
(Network Address Translation) A technology where you advertise one IP address for the world to send stuff to (e-mails, HTTP, database traffic, whatever). Then the Firebox translates that request from the outside world and sends it to the appropriate IP address inside your network. In this way, the Firebox can hide from outsiders the IP addresses of machines on your internal network. Various techniques for applying NAT include dynamic NAT, and static NAT. Some people use the term NAT interchangeably with masquerading.
Network Address Translation. A method of concealing a set of host addresses on a private network behind a pool of public addresses. It can be used as a security measure to protect the host addresses from direct targeting in network attacks.
Network Address Translation. Translating an internal networkâ€(tm)s illegal IP addresses to legal or public IP addresses. Network address translation prevents exposing the internal addresses and enables hosts with invalid addresses to communicate on the Internet, thus avoiding the need to change a networkâ€(tm)s IP addresses(a formidable, error-prone task.)
Network Address Translation - A method used by firewalls to keep a network behind under just one IP address for security reasons.
