Subject: Proposal to deprecate ip6.int reverse DNS service in APNIC
Dear colleagues,
I am submitting a proposal to deprecate ip6.int reverse DNS service in
APNIC as outlined below. I would appreciate any comments and feedback
through the mailing list, and during the APNIC 20 meeting in Hanoi.
Thank you.
Regards,
Sanjaya

prop-30-v001: Deprecation of ip6.int reverse DNS service in APNIC

----------------------------------------------------------
Proposal to deprecate ip6.int reverse DNS service in APNIC
----------------------------------------------------------
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has been replaced by ip6.arpa domain.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 is
1 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. This may occur at any time after 1 June
2006, on a date to be established in coordination with 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 support
ip6.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.
