DOMAIN NAMES - IMPLEMENTATION AND SPECIFICATION

1. STATUS OF THIS MEMO

This RFC describes the details of the domain system and protocol, and

assumes that the reader is familiar with the concepts discussed in a

companion RFC, "Domain Names - Concepts and Facilities" [RFC-1034].

The domain system is a mixture of functions and data types which are an

official protocol and functions and data types which are still

experimental. Since the domain system is intentionally extensible, new

data types and experimental behavior should always be expected in parts

of the system beyond the official protocol. The official protocol parts

include standard queries, responses and the Internet class RR data

formats (e.g., host addresses). Since the previous RFC set, several

definitions have changed, so some previous definitions are obsolete.

Experimental or obsolete features are clearly marked in these RFCs, and

such information should be used with caution.

The reader is especially cautioned not to depend on the values which

appear in examples to be current or complete, since their purpose is

primarily pedagogical. Distribution of this memo is unlimited.
