For communications, turns a symbolic address into an actual address. The best known resolver is the Domain Name Service (DNS) for TCP/IP.

a simply query-and-response protocol

A resolver is a networking component that carries out Domain Name System (DNS) queries. It is located on the client's computer.

The client part of the DNS client-server mechanism. A resolver creates queries sent across a network to a name server, interprets responses, and returns information to the requesting programs.

Software that enables clients to access the Domain Name System (DNS) database and acquire an address.

DNS client programs used to look up DNS name information. Resolvers can be either a small stub (a limited set of programming routines that provide basic query functionality) or larger programs that provide additional lookup DNS client functions, such as caching.

Refers to the client software that is used to talk to a DNS server, such as DNSd, and hence, translate Internet names into IP addresses. Since resolvers do not know the location or IP address of any DNS servers, let alone which servers they should talk to, the resolver's configuration parameters are critically important. An incorrectly configured resolver can prevent clients from getting Internet name resolution, and hence, from accomplishing any Internet-related work. The resolver on the Raptor Firewall, like all Windows NT 4.0 systems, is set in the DNS Search Order field found in Start Settings Networks Protocols Tcpip properties DNS tab.
