Network Working Group K. Harrenstien (SRI) Request for Comments: 953 M. Stahl (SRI) Obsoletes: RFC 811 E. Feinler (SRI) October 1985 HOSTNAME SERVER STATUS OF THIS MEMO This RFC is the official specification of the Hostname Server Protocol. This edition of the specification includes minor revisions to RFC 811 which brings it up to date. Distribution of this memo is unlimited. INTRODUCTION The NIC Internet Hostname Server is a TCP-based host information program and protocol running on the SRI-NIC machine. It is one of a series of internet name services maintained by the DDN Network Information Center (NIC) at SRI International on behalf of the Defense Communications Agency (DCA). The function of this particular server is to deliver machine-readable name/address information describing networks, gateways, hosts, and eventually domains, within the internet environment. As currently implemented, the server provides the information outlined in the DoD Internet Host Table Specification [See RFC-952]. For a discussion of future developments see also RFC-921 concerning the Domain Name System. PROTOCOL To access this server from a program, establish a TCP connection to port 101 (decimal) at the service host, SRI-NIC.ARPA (26.0.0.73 or 10.0.0.51). Send the information request (a single line), and read the resulting response. The connection is closed by the server upon completion of the response, so only one request can be made for each connection. QUERY/RESPONSE FORMAT The name server accepts simple text query requests of the form[ ] where square brackets ("[]") indicate an optional field. The command key is a keyword indicating the nature of the request. The defined keys are explained below. The response, on the other hand, is of the form : Harrenstien & Stahl & Feinler
