DNSIND minutes
38th IETF
Memphis, 9 April 1997
* Status of various drafts
- draft-ietf-dnsind-classless-inaddr-{00,01}.txt
The -00 draft passed working group last call some time ago, and was
passed on to the IESG. Comments received from the IESG and other
parties have been incorporated by the authors into a -01 draft which was
posted too late for ID for this meeting.
No major changes. People should be aware that nameservers which
delegate zones in this fashion should be authoritative for both the
parent and child zones, in order to reduce problems in old software with
CNAME records crossing zone boundaries.
- draft-ietf-dnsind-2ndry-04.txt
This draft relies on the Clarify draft, and will progress with it.
- draft-ietf-dnsind-clarify-{07,08}.txt
The -07 draft is available, and the -08 draft is nearly ready. There
have been no recent requests for additions to this document.
The major change in the upcoming -08 draft is clarification of what
should appear in the MNAME field of the SOA record: the name of the
master host.
WG last call will be issued when 08 is published.
- draft-ietf-dnsind-ncache-03.txt
This draft is not yet ready. See recent comments on the mailing list.
* Interoperability
The following documents are on the standards track, and the group intends
to move them to draft standard.
RFC 1995 - IXFR (currently Proposed Standard)
RFC 1996 - Notify (currently Proposed Standard)
RFC 1982 - serial number arithmetic (currently Proposed Standard)
draft-ietf-dnsind-dynDNS-11.txt - dynamic update (about to be PS)
In order for the documents to be advanced to Draft Standard, there must be
at least two interoperable, independently developed implementations. BIND
and an implementation for OS/2 are available (except that there's no IXFR
implementation for bind).
In the case of serial number arithmetic, Randy Bush will attempt to locate
or perform a formal proof of correctness, and proposes to use that in lieu
of one of the implementations. The IESG and poisson have not encouraged
this.
Stuart Kwan from Microsoft may be interested in sponsoring an
interoperability testing bake-off.
Robert Elz has an implementation of sequence space arithmetic that works
with an arbitrary number of bits. This could be tested against the 32-bit
implementations in various nameservers.
It was decided that different people will organise and report on the
testing of different components.
- Masataka Ohta will organise interoperability testing of IXFR;
- Michael Patton and Olafur Gudmundsson will organise interoperability
testing of dynamic update and secure dynamic update;
- Michael Patton will organise interoperability testing of Notify;
- Robert Elz will organise interoperability testing of serial number
arithmetic.
It was noted that there's no strict need to perform interoperability
testing of classless in-addr delegation, because that draft is intended to
become a BCP, not a Draft Standard.
* Status of DNSSEC drafts that affect DNSIND drafts
The secure dynamic update draft (draft-ietf-dnssec-update-04.txt) has been
approved by the IESG and should go to Proposed Standard. There will be at
least a six month delay before a PS can move to DS. It is expected that
the non-secure dynamic update draft (draft-ietf-dnsind-dynDNS-11.txt) will
be able to move forward on the standards track together.
* Future of the dnsind working group
I, N and D (IXFR, Notify, Dynamic update) are essentially completed.
There are some items, such as TSIG (draft-ietf-dnsind-tsig-01.txt) and the
Kitchen Sink RR (draft-eastlake-kitchen-sink-01.txt) that can conveniently
be handled by dnsind. There are other issues, such as negative cacheing
and future evolution of the DNS, that might be better handled elsewhere.
It's not clear what the most appropriate course would be.
The chair indicated that he was waiting for guidance from the IESG on what
should be done with the TSIG draft. If guidance is not forthcoming within
a week or so, a WG last call will be issued. The authors may make a quick
update first.
