Abstract

The IAB suggests that while RFC 1597 establishes reserved IP address space for the use of private networks which are isolated and will remain isolated from the Internet, any enterprise which anticipates external connectivity to the Internet should apply for a globally unique address from an Internet registry or service provider.

Abstract

The IAB suggests that while RFC 1597 establishes reserved IP address

space for the use of private networks which are isolated and will

remain isolated from the Internet, any enterprise which anticipates

external connectivity to the Internet should apply for a globally

unique address from an Internet registry or service provider.

Introduction

With the advent of RFC 1466 and RFC 1597 the criteria for the

allocation of unique IP numbers and the reservation of unique IP

numbers have been defined. The IAB and the IANA wish to offer

guidance to the Internet registries as to the application of these

two documents. The author submits this document as an informational

RFC on behalf of the Internet Architecture Board and the IANA.

Guidance to Internet Registries

RFC 1466 lists the criteria to which Internet registries should

conform. One of the criteria is that the Internet registry is

committed to allocate IP numbers according to the guidelines

established by the IANA and the IR. Those guidelines (for Classes A,

B, and C addresses) are documented in RFC 1466.

Internet Registries have agreed to comply with the guidelines

established by RFC 1466 and therefore, if an organization meets the

size requirement for the requested address(es) and submits an

engineering plan, the organization has fulfilled the necessary

requirements. The Internet Registry will make the allocation based

on the established criteria.

The preconditions defined in RFC 1466 are limited to number of hosts

and subnets as well as an engineering plan. The existence of private

address space (RFC 1597) shall not prevent an enterprise from

obtaining public address space according to the allocation criteria

(currently, RFC 1466).

An enterprise may be required by a Internet registry to submit an

engineering plan documenting a realistic deployment schedule and

reasonable attention to conservation of address space to support the

size of the enterprise's request for globally unique IP addresses.

It is perfectly appropriate for an Internet registry to inform an

organization of the provisions of RFC 1597. Any organization

considering the use of private network numbers should carefully

consider the potential advantages and possible problems as discussed

in RFCs 1597 and 1627.

RFC 1597 establishes reserved IP address space for the use of private

networks which are isolated and will remain isolated from the

Internet. Thus RFC 1597 documents a way that private enterprises may
