I have reviewed this document as part of the IntDir directorate's ongoing
effort to review all IETF documents being processed by the IESG. Comments that
are not addressed in last call may be included in AD reviews during the IESG

any other last call comments.

Title: Entering IPv6 Zone Identifiers in User Interfaces
Document: draft-ietf-opsawg-prefix-lengths-08

This standard track document specifies how to augment the RPSL inetnum. It 
also describes an optional scheme that uses the RPKI to authenticate the 
prefixlen files. It is well-written. I do not find any obvious technical 
issues or Nits. It is ready for publication as a RFC.
