Network Working Group M. Andrews Internet-Draft ISC Expires: April 14, 2013 October 11, 2012 Add 100.64.0.0/10 prefixes to IPv4 Locally-Served DNS Zones registry. draft-andrews-dnsop-rfc6598-rfc6303-01 Abstract RFC6598 specified that: "reverse DNS queries for 100.64/10 MUST NOT be forwarded to the global DNS infrastructure". This document formally directes 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.

Introduction [RFC6598] specified that "reverse DNS queries for 100.64/10 MUST NOT be forwarded to the global DNS infrastructure". [RFC6303] provides guidance on handling such queries. This document directs the IANA to add the IPv4 reverse zones corresponding to 100.64.0.0/10, a netblock reserved in [RFC6598], to the IPv4 Locally-Served DNS Zone Registry established in [RFC6303]. Unlike [RFC1918] address, which are not expected to be seen by other parties, the addresses from [RFC6598] are expected to be seen by parties other than those deploying the addresses, so it is more crucial that recursive nameservers default to serving these zones locally. 2. Changes to IPv4 Locally-Served DNS Zones To add the following zone listed in RFC6598 Zones (Section 2.1) to the "IPv4 Locally-Served DNS Zone" registry. 2.1.

IANA Considerations This document directs IANA to add the zones listed in RFC6598 Zones (Section 2.1) to the "IPv4 Locally-Served DNS Zone" registry.
