Abstract

This document updates the specification of the WHOIS protocol, thereby obsoleting RFC 954. The update is intended to remove the material from RFC 954 that does not have to do with the on-the-wire protocol, and is no longer applicable in today's Internet. This document does not attempt to change or update the protocol per se, or document other uses of the protocol that have come into existence since the publication of RFC 954.

Abstract

   This document updates the specification of the WHOIS protocol,

   thereby obsoleting RFC 954.  The update is intended to remove the

   material from RFC 954 that does not have to do with the on-the-wire

   protocol, and is no longer applicable in today's Internet.  This

   document does not attempt to change or update the protocol per se, or

   document other uses of the protocol that have come into existence

   since the publication of RFC 954.

1.  Introduction

   WHOIS is a TCP-based transaction-oriented query/response protocol

   that is widely used to provide information services to Internet

   users.  While originally used to provide "white pages" services and

   information about registered domain names, current deployments cover

   a much broader range of information services.  The protocol delivers

   its content in a human-readable format.  This document updates the

   specification of the WHOIS protocol, thereby obsoleting RFC 954 [1].

   For historic reasons, WHOIS lacks many of the protocol design

   attributes, for example internationalisation and strong security,

   that would be expected from any recently-designed IETF protocol.

   This document does not attempt to rectify any of those shortcomings.

   Instead, this memo documents the WHOIS protocol as it is.  In some

   areas, this document does document particular well known shortcomings

   of the WHOIS protocol.  The discussion of possible protocols to carry

   out these functions, with updated capabilities to address the

   shortcomings, is being addressed in a separate IETF activity (CRISP

   Working Group).

2.  Protocol Specification

   A WHOIS server listens on TCP port 43 for requests from WHOIS

   clients.  The WHOIS client makes a text request to the WHOIS server,

   then the WHOIS server replies with text content.  All requests...
