Adding 100.64.0.0/10 Prefixes to the IPv4 Locally-Served DNS Zones Registry
RFC 7793, “Adding 100.64.0.0/10 Prefixes to the IPv4 Locally-Served DNS Zones Registry”, is a Best Current Practice document published in May 2016 by M. Andrews. The canonical text is published by the RFC Editor.
Abstract
RFC 6598 specifies 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 from accidentally leaking to the global DNS infrastructure.
What “Best Current Practice” means
Documents the IETF community's recommended operational or procedural practice rather than a protocol specification.
