I have reviewed this document as part of the security directorate's ongoing effort to review all IETF documents being processed by the IESG.  These comments were written primarily for the benefit of the security area directors.  Document editors and WG chairs should treat these comments just like any other last call comments.

This document is intended for Informational status. It describes operational considerations for AS112 nameservers, whose purpose in life is to provide a distributed sink for reverse DNS queries corresponding to private-use IP addresses (e.g. RFC 1918 addresses). 

The security considerations section seems well thought out, and I see no security issues with this document.
