ARPA Host Name Server Protocol
The ARPA Host Name Server Protocol (NAMESERVER)[1] is an obsolete network protocol used in translating a host name to an Internet address. IANA Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) port 42 for NAMESERVER; this port is more commonly used by the Windows Internet Name Service (WINS) on Microsoft operating systems.
Application
[edit ]The NAMESERVER protocol is used by the DARPA Trivial Name Server, a server process called tnamed that is provided in some implementations of UNIX.[2] [3] [4]
Replacement
[edit ]Support for the NAMESERVER protocol has been deprecated, and may not be available in the latest implementations of all UNIX operating systems.[5] The Domain Name System (DNS) has replaced the ARPA Host Name Server Protocol and the DARPA Trivial Name Server.
