4.10. IESG Approval

New assignments may be approved by the IESG. Although there is no requirement that the request be documented in an RFC, the IESG has the discretion to request documents or other supporting materials on a case-by-case basis.

IESG Approval is not intended to be used often or as a "common case"; indeed, it has seldom been used in practice. Rather, it is intended to be available in conjunction with other policies as a fall-back mechanism in the case where one of the other allowable approval mechanisms cannot be employed in a timely fashion or for some other compelling reason. IESG Approval is not intended to circumvent the public review processes implied by other policies that could have been employed for a particular assignment. IESG Approval would be appropriate, however, in cases where expediency is desired and there is strong consensus (such as from a working group) for making the assignment.

Before approving a request, the IESG might consider consulting the community, via a "call for comments" that provides as much information as is reasonably possible about the request.

Examples:

• IPv4 Multicast address assignments [RFC5771]
• IPv4 IGMP Type and Code values [RFC3228]
• Mobile IPv6 Mobility Header Type and Option values [RFC6275]
