The IESG has approved the following document: - 'Add 100.64.0.0/10 prefixes to IPv4 Locally-Served DNS Zones Registry.' (draft-ietf-dnsop-rfc6598-rfc6303-05.txt) as Best Current Practice This document is the product of the Domain Name System Operations Working Group. The IESG contact persons are Benoit Claise and Joel Jaeggli. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-dnsop-rfc6598-rfc6303/ Technical Summary This document adds the reverse address zones for 100.64.0.0/10 to the "Locally Served DNS Zones Registry." This will encourage DNS administrators to include those zones in configurations to resolve them locally, in compliance with RFC6598, and help prevent leakage of such queries to the global DNS. Working Group Summary The WG found that this is a straightforward update to a well-known and widely used registry, to support deployment of IPv6 via the mechanism described in RFC 6598. Document Quality The document is brief and clear as to its intended purpose, which is quite simple. The effect of local resolution of these names is in compliance with RFC 6598. Guidance to operators making it easier for them to do so supports orderly deployment of RFC 6598 (Carrier Grade NAT). Personnel Shepherd: Suzanne Woolf AD: Joel Jaeggli
