                   Adding 100.64.0.0/10 Prefixes to the                  IPv4 Locally-Served DNS Zones Registry

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.
