Abstract

This document specifies the IANA guidelines for allocating new values for the Routing Type field in the IPv6 Routing Header.

1.  Introduction

This document specifies the IANA guidelines [RFC5226] (Narten, T. and H. Alvestrand, “Guidelines for Writing an IANA Considerations Section in RFCs,” May 2008.) for allocating new values for the Routing Type field in the IPv6 Routing Header [RFC2460] (Deering, S. and R. Hinden, “Internet Protocol, Version 6 (IPv6) Specification,” December 1998.). Previously, no IANA guidance existed for such allocations.

2.  IANA Considerations

New Routing Type values are allocated through IETF Review or IESG Approval [RFC5226] (Narten, T. and H. Alvestrand, “Guidelines for Writing an IANA Considerations Section in RFCs,” May 2008.).

Note that two experimental values (253 and 254) are already available for use [RFC4727] (Fenner, B., “Experimental Values In IPv4, IPv6, ICMPv4, ICMPv6, UDP, and TCP Headers,” November 2006.).

3.  Security Considerations

This specification does not change the security properties of the Routing Header. However, past experience shows that it is easy to design routing headers that have significant problems [RFC5095] (Abley, J., Savola, P., and G. Neville-Neil, “Deprecation of Type 0 Routing Headers in IPv6,” December 2007.).
