[as112-ops] Request to add service.arpa to AS112

[Kim Davies]

Dear AS112 operators:

IANA is being being asked to implement the IANA considerations of a
new RFC-to-be, draft-ietf-dnssd-srp-25, which requires delegation of
"service.arpa" to black hole servers as follows:

   In order to be fully functional, the owner of the 'arpa.' zone must
   add a delegation of 'service.arpa.' in the '.arpa.' zone [RFC3172].
   This delegation is to be set up as was done for 'home.arpa', as a
   result of the specification in Section 7 of [RFC8375]. This is
   currently the responsibility of the IAB [IAB-ARPA]

   <https://datatracker.ietf.org/doc/html/draft-ietf-dnssd-srp-25#delegation>

Therefore, just as with home.arpa we are requesting AS112 operators to
configure their AS112 nodes as soon as practical to answer queries for
this new zone on blackhole-[12].iana.org, so that we may delegate it in
the .arpa zone with those two NS records. The zone should be configured
with the "db.dd-empty" zone content described in RFC 7534.

I suspect one of the questions will be whether we can use DNAME as
described in RFC 7535. While we have made some progress in separating
root server infrastructure from .ARPA infrastructure (see RFC 9120),
that work has not concluded and today they are still served through
common infrastructure.

Our intention is to add the delegation to the .ARPA zone around mid-May,
to provide AS112 operators time to make this configuration update.

Thank you in advance, and if you have any questions please let me know,
or respond back to this group.

Kindest regards,
