Dear colleaguesAPNIC welcomes comments, questions, and suggestions on the following policy
proposal: ____________________ Final call for comments: [prop-030-v002] " Deprecation of ip6.int reverse DNS service in APNIC" ____________________ This is the final call for comments on policy proposal [prop-030-v002] "Deprecation of ip6.int reverse DNS service in APNIC". This is a proposal that APNIC cease devoting resources to support the operation of the ip6.int domain at a date to be determined jointly with the other RIRs. This proposal was presented at APNIC 20 and the following consensus was reached: "The SIG accepted by consensus the proposed policy process, which requires the text proposal to be sent to the mailing list one month before the meeting, an eight week comment period on the mailing list after the meeting, and final endorsement from EC." This proposal is now submitted to the sig-dns mailing list for an eight week discussion period. At the end of that period, if consensus appears to have been achieved, the Chair of the DNS Operations SIG will ask the Executive Council to endorse the proposal for implementation. * Send all comments and questions to: <sig-dns at apnic dot net> * Deadline for comments: 16 November 2005 _____________________________________________________________________ Proposal details _____________________________________________________________________ Author: Sanjaya <sanjaya at apnic dot net> Version: 2.0 Date: 8 September 2005 Introduction ------------The use of the ip6.int domain was deprecated in August 2001 (RFC 3152). It has been replaced by ip6.arpa domain. The RFC indicated that the use of the
ip6.int domain was "likely be phased out in an orderly fashion". An individual Internet Draft has been submitted by Geoff Huston(draft-huston-ip6-int-03.txt) to deprecate ip6.int, and proposing that the
Regional Internet Registries are no longer required to maintain the delegation of entries in ip6.int. The date nominated in that draft is1 September 2005. This draft has been submitted into the IETF's Standards track and is currently being considered by the IESG for adoption as an RFC.
APNIC has stopped accepting updates to ip6.int domain for the last one year, since June 2004. However, the APNIC DNS servers are still getting roughly 5
queries per minute on this domain. Proposal Summary ---------------- With the acceptance of draft-huston-ip6-int-03 as an RFC, it is proposed that APNIC cease devoting resources to support the operation of this deprecated domain, at a date no earlier than 1 June 2006. Situation in other RIRs ----------------------- Other RIRs are facing this issue, and are likely to take action in due course. LACNIC has consulted its community and is currently preparing to cease ip6.int support. ARIN, RIPE and AFRINIC can be expected to present this issue in their respective communities at a later date. Details of your proposal ------------------------ APNIC domain name servers will cease answering ip6.int reverse domain queries after a specific date. The cut off date is to be determined jointly with the other RIRs. The following steps are proposed to ensure orderly cutoff and minimise operational impact: - Notify the parties who have been sending ip6.int queries to APNIC servers (2 weeks after EC approval) - Monitor the DNS traffic for ip6.int queries - Send final reminder to the parties still sending ip6.int queries (4 weeks before 1 June 2006) - Send public announcements through newsletter, website, MyAPNIC, mailing lists (as needed) - Notify root ip6.int to remove APNIC delegation on the cutoff date (1 week and 1 day prior) - Remove ip6.int entries in APNIC domain name servers and restart the service (cutoff date to be determined later) - Report completion of the project in APNIC 22 meeting (September 2006) Advantages and disadvantages of adopting the proposed policy ------------------------------------------------------------With the implementation of this policy, only one IPv6 reverse DNS service is maintained: ip6.arpa. This should prevent confusion by the end users and
network administrators, while freeing APNIC resources to more productive work. Legacy IPv6 applications that use ip6.int domain and do not supportip6.arpa will no longer obtain valid DNS results. However, since updates to
ip6.int ceased some time ago, such results have been incomplete or inaccurate for at least 1 year. Additionally it is expected that the affected parties will have been well informed by the IETF's standards action as well as by the operational steps outlined above. Effect on APNIC members ----------------------- - Members using legacy IPv6 applications should migrate to the latest version that supports ip6.arpa - Members receiving ip6.int delegation from APNIC should cease operating their ip6.int domain. Effect on NIRs -------------- - NIRs receiving ip6.int delegation from APNIC should cease operating their ip6.int domain.
