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.
specified that: "Reverse DNS queries
for Shared Address Space addresses [100.64.0.0/10] MUST NOT
be forwarded to the global DNS infrastructure." 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 , to the IPv4 Locally-Served DNS Zone
Registry established in .
Unlike address, which are not
expected to be seen by other parties, the addresses from
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.
To add the following zone listed in
RFC6598 Zones to the
"IPv4 Locally-Served DNS Zone Registry".

This document directs IANA to add the zones listed in RFC6598 Zones to the
"IPv4 Locally-Served DNS Zone Registry".
This document is thought to present no additional security
risks to the Internet.
I would like to thank Joe Abley for his review comments.
