Following advanced notice sent to this list on 2010-08-03, the IANA testbed was shut down on 2010-09-03.
For more details on the IANA DNSSEC testbed, see https://ns.iana.org/.
For more details on DNSSEC deployment in the Root Zone, see http://www.root-dnssec.org/.
Queries to the nameserver bound to NS.IANA.ORG (184.108.40.206, 2620:0:2d0:1::32) now fail with ICMP type 3 code 3 (Destination Unreachable, Port Unreachable).
We suggest that anybody using the DNSSEC testbed for anything resembling production services make plans to stop doing so at their earliest convenience, if operational necessity has not already made that obvious.
ICANN would once again like to thank Packet Clearing House (PCH) and Dyn.com DynTLD for their support and generous donation of global DNS resources to the IANA DNSSEC testbed.
