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.

An Internet Protocol (IP) translation process that allows a network with private addresses to access information on the Internet.

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.

NAT is a process for increasing the number of IP address inside a private company network. The NAT process registers the IP addresses of a private network and assigns them a publicly registered IP address. The advantage of this process is that computers that only communicate with each other within the company network do not require public IP addresses. Computers which communicate with other, external computers receive a designation number during routing.

NAT is the translation of a protocol used within one network to a different protocol known within another network. Return to .

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.

A mechanism for translating network addresses into private addresses. This is discussed in gory detail in RFC 1918. The Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of the IP address space for private internets: 10.0.0.0 - 10.255.255.255 (10/8 prefix), 172.16.0.0 -172.31.255.255 (172.16/12 prefix), amd 192.168.0.0 - 192.168.255.255 (192.168/16 prefix)

An internet standard that increases security by enabling 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, this feature is often built into routers.

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 whereby a single host comptuer or router connected to internet can relay messages both to and from internally connected hosts (not directly connected to the internet). It effectively allows multiple computers to use the internet from a single IP address.

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.

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.

A type of network connection that allows you to connect your virtual machines to an external network when you have only one IP network address, and that address is used by the host computer. If you use NAT, your virtual machine does not have its own IP address on the external network. Instead, a separate private network is set up on the host computer. Your virtual machine gets an address on that network from the VMware virtual DHCP server. The VMware NAT device passes network data between one or more virtual machines and the external network. It identifies incoming data packets intended for each virtual machine and sends them to the correct destination.

A process that modifies either the source IP address or destination IP address of an IP packet.

NAT is used on local area networks for two purposes: security and Inernet access. To the external network (outside the organization) only the NAT server is visible, and it appears as a single Internet address. However, inside the network there can be dozens or even hundreds of machines. The NAT server assigns to each its own unique internal address. These addresses are not revealed to the outside world and n any case are not routable. Hence, these machines cannot be contacted from the outside and thus are protected from attack. The second purpose is achieved by not requiring each machine to have an Internet-wide unique IP address; it must be unique only within the local network. Access to the Internet is provided through the NAT server which conceals the internal addresses.

NAT. The translation of an IP address used within one network to a different IP address known within another network. Used to limit the number of global IP addresses that are needed.

Network address translation is a form of IP address masquerading. It ensures that internal private (RFC1918) network addresses from packets inside the network are rewritten so that TCP/IP packets that leave the server over a public connection are seen to come only from the external network address.

A method that many ISPs use to extend their IP addressing to support more addresses than they own. The interior network uses one addressing scheme, and...

(NAT) An algorithm that minimises the requirement for globally unique IP addresses. Typically used to enable hosts on a private network to connect to the internet without having unique IP addresses (or Internet-routable IP addresses).

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.

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.

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. For instance, though an ISP assigns only one external IP number to a home network, the router connecting the home network allows the computers attached to it to share that single IP by assigning them each their own internal identity.

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.

A standard that allows your Internet connected devices to use private IP addresses that are not recognized on the Internet. By using a device that includes NAT in between your modem and computer, your computer can access the Internet but the other users of Internet can not access your computer. Once considered sufficient security now thought of as only one part of a multiple layered Internet security strategy. Close Window

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.

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 the other is the external. The internal network then appears as one entity to the outside world.

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).

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.)
