Introduction

This RFC defines the format of new Resource Records (RRs) for the Domain Name System (DNS), and reserves corresponding DNS type mnemonics and numerical codes. The definitions are in three independent sections: (1) location of AFS database servers, (2) location of responsible persons, and (3) representation of X.25 and ISDN addresses and route binding. All are experimental.

This RFC assumes that the reader is familiar with the DNS [3,4]. The data shown is for pedagogical use and does not necessarily reflect the real Internet.

RFC 1183 New DNS RR Definitions October 1990

1. AFS Data Base location

This section defines an extension of the DNS to locate servers both for AFS (AFS is a registered trademark of Transarc Corporation) and for the Open Software Foundation’s (OSF) Distributed Computing Environment (DCE) authenticated naming system using HP/Apollo’s NCA, both to be components of the OSF DCE. The discussion assumes that the reader is familiar with AFS [5] and NCA [6].

The AFS (originally the Andrew File System) system uses the DNS to map from a domain name to the name of an AFS cell database server. The DCE Naming service uses the DNS for a similar function: mapping from the domain name of a cell to authenticated name servers for that cell. The method uses a new RR type with mnemonic AFSDB and type code of 18 (decimal).

AFSDB has the following format:

<owner> <ttl> <class> AFSDB <subtype> <hostname>

Both RDATA fields are required in all AFSDB RRs. The <subtype> field is a 16 bit integer. The <hostname> field is a domain name of a host that has a server for the cell named by the owner name of the RR.
