Deployment of the Internet White Pages Service

RFC 2148              Internet White Pages Service        September 1997


     (2)   Internet Service providers SHOULD help smaller
           organizations follow this recommendation, either by providing
           services for hosting their data, by helping them find other
           parties to do so, or by helping them bring their own service
           on-line.

     (3)   All interested parties SHOULD make sure there exists a core
           X.500 name space in the world, and that all names in this
           name space are resolvable. (National name spaces may
           elobarate on the core name space).

   The rest of this document is justification and details for this
   recommendation.

   The words "SHOULD", "MUST" and "MAY", when written in UPPER CASE,
   have the meaning defined in RFC 2119 [17]

2.  Introduction

   The Internet is used for information exchange and communication
   between its users. It can only be effective as such if users are able
   to find each other's addresses. Therefore the Internet benefits from
   an adequate White Pages Service, i.e., a directory service offering
   (Internet) address information related to people and organizations.

   This document describes the way in which the Internet White Pages
   Service (from now on abbreviated as IWPS) is best exploited using
   today's experience, today's protocols, today's products and today's
   procedures.

   Experience [2] has shown that a White Pages Service based on self-
   registration of users or on centralized servers tends to gather data
   in a haphazard fashion, and, moreover, collects data that ages
   rapidly and is not kept up to date.

   The most vital attempts to establish the IWPS are based on models
   with distributed (local) databases each holding a manageable part of
   the IWPS information. Such a part mostly consists of all relevant
   IWPS information from within a particular organization or from within
   an Internet service provider and its users. On top of the databases
   there is a directory services protocol that connects them and
   provides user access. Today X.500 is the most popular directory
   services protocol on the Internet, connecting the address information
   of about 1,5 million individuals and 3,000 organizations. Whois++ is
   the second popular protocol. X.500 and Whois++ may also be used to
   interconnect other information than only IWPS information, but here
   we only discuss the IWPS features.
