[arin-announce] Planned Changes to IPv4 Reverse DNS Infrastructure

[ARIN]

ARIN and ICANN are planning changes to the infrastructure which supports 
the IPv4 Reverse DNS, the part of the DNS which provides the ability to 
look up an IPv4 address and convert it to a name.

With this change the IN-ADDR.ARPA zone will move to new, dedicated 
nameservers, five operated by the Regional Internet Registries (RIRs) 
and one operated by ICANN.

ARIN has carried out the DNS zone maintenance function for IN-ADDR.ARPA 
since 1997. This function will transition in February 2011 to ICANN and 
will be managed concurrently with the central assignment of IPv4 address 
space to RIRs. Once the IN-ADDR.ARPA zone is being maintained by ICANN 
it will also be signed using DNS Security Extensions (DNSSEC), providing 
end-users with the ability to validate answers to reverse DNS queries.
