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
2. IANA Considerations
New Routing Type values are allocated through IETF Review or IESG
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].
