Internet Engineering Task Force (IETF) M. Cotton Request for Comments: 7120 ICANN BCP: 100 January 2014 Obsoletes: 4020 Category: Best Current Practice ISSN: 2070-1721 Early IANA Allocation of Standards Track Code Points Abstract This memo describes the process for early allocation of code points by IANA from registries for which "Specification Required", "RFC Required", "IETF Review", or "Standards Action" policies apply. This process can be used to alleviate the problem where code point allocation is needed to facilitate desired or required implementation and deployment experience prior to publication of an RFC, which would normally trigger code point allocation. The procedures in this document are intended to apply only to IETF Stream documents. This document obsoletes RFC 4020. Status of This Memo This memo documents an Internet Best Current Practice. This document is a product of the Internet Engineering Task Force (IETF). It represents the consensus of the IETF community. It has received public review and has been approved for publication by the Internet Engineering Steering Group (IESG). Further information on BCPs is available in Section 2 of RFC 5741.

Introduction In protocol specifications documented in RFCs, there is often a need to allocate code points for various objects, messages, or other protocol entities so that implementations can interoperate. Many of these code point spaces have registries handled by the Internet Assigned Number Authority (IANA). Several IETF policies for IANA allocation of protocol parameters are described in RFC 5226 [RFC5226]. Some of them, such as "First Come First Served" or "Expert Review", do not require a formal IETF action before the IANA performs allocation. However, in situations where code points are a scarce resource and/or the IETF community has consensus to retain tight control of the registry content, policies such as "IETF Review" (formerly "IETF Consensus"), or "Standards Action" have been used. Such allocation policies present a problem in situations where implementation and/or deployment experience are desired or required before the document becomes an RFC. To break the deadlock, document authors often choose some "seemingly unused" code points, often by selecting the next available value from the registry; this is problematic because these may turn out to be different from those later assigned by IANA. To make this problem worse, "pre-RFC" implementations are often developed and deployed based on these code point selections. This creates several potential interoperability problems between early implementations and implementations of the final standard, as described below:Show full document text
