The IESG has received a request from the Domain Name System Operations WG (dnsop) to consider 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 The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2015-11-23. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract RFC6598 specified that: "Reverse DNS queries for Shared Address Space addresses [100.64.0.0/10] MUST NOT be forwarded to the global DNS infrastructure." This document formally directs IANA to add the associated zones to the "IPv4 Locally-Served DNS Zones Registry" to prevent such queries accidently leaking to the global DNS infrastructure. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-dnsop-rfc6598-rfc6303/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-dnsop-rfc6598-rfc6303/ballot/ No IPR declarations have been submitted directly on this I-D.
