In December we spoke of the planned changes to the IPv4 Reverse DNS Infrastructure where the zone maintenance of the IN-ADDR.ARPA zone would transition to ICANN and be managed concurrently with the central assignment of address space to the RIRs.

ICANN would like to announce that the transition of the technical management function for the IN-ADDR.ARPA zone from ARIN to ICANN has been completed. ICANN would also like to thank ARIN for carrying out the DNS zone maintenance function for IN-ADDR.ARPA since 1997 and their cooperation during this transition period.

For more details on the history of this transition please see the project web page.
