Abstract

This RFCconsiders X.500 in relation to Internet and UK Domains. A basic model of X.500 providing a higher level and more descriptive naming structure is emphasised. In addition, a mapping of domains onto X.500 is proposed, which gives a range of new management and user facilities over and above those currently available. This specification proposes an experimental new mechanism to access and manage domain information on the Internet and in the UK Academic Community. There is no current intention to provide an operational replacement for DNS.

 1  The Domain Name System

The Domain (Nameserver) System (DNS) provides a hierarchical resource labelling system [Moc87a] [Moc87b] [Lar83].  Example domains are:

MIT.EDU VENERA.ISI.EDU CS.UCL.AC.UK

 Entries usually have a single name, although pointers to entries (not subtrees) may be provided by CNAME records.  Information (resource records) is associated with each entry.  Name components are typically chosen to be shortish (e.g., ``CS''). RFC 822 mailbox names are closely related [Cro82].  For example:

     <S.Kille@CS.UCL.AC.UK>

The local-part of the RFC 822 mailbox can be considered as one level lower in the domain hierarchy.

 2  X.500

The OSI Directory, usually known as X.500, provides a very general naming framework [CCI88].  A basic usage of X.500 is to provide Organisationally Structured Names.  A Schema for this is defined within the standard.  Name components will typically have longish values.  This is an example directory name represented in Tabular form:

            Country              GB            Organisation         University College London            Organisational Unit  Computer Science            Common Name          Stephen E. Hardcastle-Kille

This can also be written in the ``User Friendly Name'' notation defined in [HK91].  This syntax ...
