Abstract

This RFC defines the format of two new Resource Records (RRs) for the Domain Name System (DNS), and reserves corresponding DNS type mnemonic and numerical codes. This format may be used with the any proposal that has variable length addresses, but is targeted for CLNP use.

Introduction

This RFC defines the format of two new Resource Records (RRs) for the

Domain Name System (DNS), and reserves corresponding DNS type

mnemonic and numerical codes. This format may be used with the any

proposal that has variable length addresses, but is targeted for CLNP

use.

This memo assumes that the reader is familiar with the DNS [3,4].

Background

This section describes an experimental representation of NSAP

addresses in the DNS. There are several reasons to take this approch.

First, it provides simple documentation of the correct addresses to

use in static configurations of CLNP compliant hosts and routers.

NSAP support requires that a new DNS resource record entry type

("NSAP") be defined, to store longer Internet (i.e., NSAP) addresses.

This resource record allows mapping from DNS names to NSAP addresses,

and will contain entries for systems which are able to run Internet

applications, over TCP or UDP, over CLNP.

The backward translation (from NSAP address to DNS name) is

facilitated by definition of an associated resource record. This

resource record is known as "NSAP-PTR", and is used in a manner

analogous to the existing "in-addr.arpa".

These RRs are intended for use in a proposal [6] by one of the

members of the NOOP WG to address the next-generation internet.

The NSAP RR

The NSAP RR is defined with mnemonic NSAP and type code 22 (decimal).

An NSAP (Network Service Access Protocol) number is a unique string

to OSI transport service.

The numbering plan follows RFC 1237 and associated OSI definitions

for NSAP format.

NSAP has the following format:
