This is the final update for the IN-ADDR.ARPA transition work.
The IN-ADDR.ARPA DNSSEC Delegation Signer record has been added to the ARPA zone.
This action now extends the DNSSEC validation chain to the IN-ADDR.ARPA zone.
No further updates will be posted to this project web site.
A note of thanks is extended to all the people and entities involved in this work: ARIN for their co-operation in the transition and for acting as the technical administrator of the IN-ADDR.ARPA zone, the operators of the 12 root-servers who carried the IN-ADDR.ARPA zone for many years, and the RIRs (RIPE-NCC, ARIN, LACNIC, APNIC, and AfriNIC) for taking on the role of operating the RFC5855 nameservers.
