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. This memo provides information for the Internet community. This memo does not specify an Internet standard of any kind.

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.

RFC 1814 Unique Addresses are Good June 1995

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 assure that their networks will remain segregated from the Internet. The addresses designated in RFC 1597 should not be routed by the ...
