RFC 5237, “IANA Allocation Guidelines for the Protocol Field”, is a Best Current Practice document published in February 2008 by J. Arkko, S. Bradner. It updates RFC 2780. The canonical text is published by the RFC Editor.
Abstract
This document revises the IANA guidelines for allocating new Protocol field values in IPv4 header. It modifies the rules specified in RFC 2780 by removing the Expert Review option. The change will also affect the allocation of Next Header field values in IPv6. This document specifies an Internet Best Current Practices for the Internet Community, and requests discussion and suggestions for improvements.
