New name servers for IN-ADDR.ARPA

RFC 5855 “Nameservers for IPv4 and IPv6 Reverse Zones” specifies a dedicated and stable set of nameserver names for each of the IN-ADDR.ARPA and IP6.ARPA zones.

Currently IN-ADDR.ARPA is served by a subset of the DNS root servers.

The secure and stable hosting of the IN-ADDR.ARPA and IP6.ARPA zones is critical to the operation of the Internet, since many applications rely upon timely responses to reverse lookups to be able to operate normally.
As a part of the transition process the IN-ADDR.ARPA will be delegated to the following servers operated by ICANN and the 5 RIRs.
  • A.IN-ADDR-SERVERS.ARPA (operated by ARIN)
  • B.IN-ADDR.SERVERS.ARPA (operated by ICANN)
  • C.IN-ADDR.SERVERS.ARPA (operated by AfriNIC)
  • E.IN-ADDR.SERVERS.ARPA (operated by APNIC)

This exercise of delegating a reverse zone to a stable set of names has already been undertaken and completed for IP6.ARPA.
