ARPA Host Name Server Protocol
{{Short description|Obsolete hostname lookup protocol}}
The ARPA Host Name Server Protocol (NAMESERVER)[http://www.ietf.org/rfc/rfc1011.txt OFFICIAL INTERNET PROTOCOLS (see "IEN 116" at top of page 31)] 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
The NAMESERVER protocol is used by the DARPA Trivial Name Server, a server process called tnamed that is provided in some implementations of UNIX.[http://www.cs.rit.edu/~hpb/Man/_Man_NeXT_html/html8/tnamed.8c.html DARPA Trivial Name Server NeXT NEXTSTEP documentation][http://docs.sun.com/app/docs/doc/820-1259/gevqv?l=ko&a=view DARPA Trivial Name Server Sun Solaris documentation]{{dead link|date=October 2016 |bot=InternetArchiveBot |fix-attempted=yes }}[http://uw713doc.sco.com/en/man/html.1Mtcp/tnamed.1Mtcp.html Trivial Name Server SCO UnixWare documentation] {{webarchive |url=https://web.archive.org/web/20110716015415/http://uw713doc.sco.com/en/man/html.1Mtcp/tnamed.1Mtcp.html |date=July 16, 2011 }}
Replacement
Support for the NAMESERVER protocol has been deprecated, and may not be available in the latest implementations of all UNIX operating systems.[http://www.math.utah.edu/~beebe/unix/i/in.tnamed.html Somewhat incomplete list of UNIX operating systems that either support or do not support the DARPA Trivial Name Server (tnetd)] The Domain Name System (DNS) has replaced the ARPA Host Name Server Protocol and the DARPA Trivial Name Server.
