1 Deprecation of ip6.int reverse DNS service in APNIC Project update IPv6 technical SIG, APNIC 21 1 March 2006 Sanjaya

2 Overview Background Proposal Project status –Observations/statistics –Coordination work –Schedule Q & A

3 Background Use of the ip6.int domain deprecated Aug 2001 (RFC 3152) BCP 109, RFC 4159 (Aug 2005) states – The Regional Internet Registries (RIRs) are advised that maintenance of delegation of entries in "ip6.int" is no longer required as part of infrastructure services in support of Internet Standards conformant IPv6 implementations as of 1 September APNIC has stopped accepting new ip6.int domains as of Jun 2004 Query rate for ip6.int domains is still around 5 queries/minute

4 prop-030-v002 It is proposed that APNIC cease devoting resources to support the operation of this deprecated domain. The cut off date to be determined jointly with the other RIR

5 Proposal Proposed steps to ensure orderly cut off –Notify parties who are sending ip6.int queries to APNIC DNS servers, that APNIC is stopping the service –Send public announcements –Notify root ip6.int to remove APNIC delegation on the cutoff date –Remove ip6.int entries in APNIC DNS on cutoff date –Report project status in APNIC 21 (End Feb 2006)

6 Observations/statistics Most IP6 dataflow is from listed NS of domains –Zone refresh (SOA) checks –Zone notify from masters on update Decline in ip6.int related load seen –Nov 2005, 2 days measurement –Feb 2006, 6 days measurement

7 Query load per minute, int/arpa

8 Non-NS query load Faulty linux PTR queries

9 How many NS worldwide? DomainNovember 2005February 2006 ip6.int3629 ip6.arpa Very few discrete NS request services in IP6.int Query rates are low (<2q/min) PTR queries dominated by faulty linux – going to ip6.arpa NS, not sub-reverses

10 Coordination work Other RIRs –Agreement to coordinate as a global activity Public communications Technical activities –Will cease ip6.int on the same date NIR –Consult each NIR community to check for issues or scheduling conflicts Root ip6.int –Consultation of activities and schedules (in plan)
