1. Introduction

This document specifies the IANA guidelines [RFC5226] for allocating new values for the Routing Type field in the IPv6 Routing Header [RFC2460]. Previously, no IANA guidance existed for such allocations.

2. IANA Considerations

New Routing Type values are allocated through IETF Review or IESG Approval [RFC5226].

Note that two experimental values (253 and 254) are already available for use [RFC4727].

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].
