Abstract

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.

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

:

where is a keyword indicating the nature of the response, and the rest of the response is interpreted in the context of the key.

NOTE: Care should be taken to interpret the nature of the reply (e.g, single record or multiple record), so that no confusion about the state of the reply results. An "ALL" request will likely return several hundred or more records of all types, whereas "HNAME" or "HADDR" will usually return one HOST record.

COMMAND/RESPONSE KEYS

The currently defined command keywords are listed below. NOTE: Because the server and the features available will evolve with time, the HELP command should be used to obtain the most recent summary of implemented features, changes, or new commands.
