    Description of Working Group:

    DNS was originally specified in RFC's 1034 and 1035, with subsequent
    updates.  Within the scope of this WG are DNS protocol issues,
    including the specification of message formats, message handling, and
    data formats used for DNS client-server and server-server
    communication.

    This WG is focused on advancing the zone transfer, update, notify
    and DNSSECbis documents to Draft standard.

    The WG works on solutions for DNSSEC deployment issues that may
    require protocol modifications. Two of these issues are identified
    and are worked on under the umbrella of this WG. 1] (a) method(s) to
    prevent the possibility of trivial zone enumeration and 2] a method
    for automated rollover of trust-anchors configured in validating
    resolvers.

    Issues surrounding the operation of DNS, recommendations concerning
    the configuration of DNS servers, and other issues with the use of
    the protocol are out of scope for this Working Group.  These issues
    are considered in other venues, such as the DNS Operations Working
    Group.

    The DNSEXT Working Group sometimes uses an additional mailing list
    for discussion of DNS Security related issues. This list is open to
    all

      Discussion: dnssec@cafax.se
      To Subscribe: dnssec-request@cafax.se
      Archive:  http://www.cafax.se/dnssec/ and
                ftp://ftp.cafax.se/pub/archives/dnssec.list

    The 2535bis document set was edited by a team. This team was
    chartered with making editorial changes only, with all substantiative
    changes discussed on the WG list. The archive of this editors-only
    mailing list is available at:
     
      http://www.east.isi.edu/projects/DNSSEC

    Specific work items are:

          o Advance the DNSSECbis document set through the standards
            process.

          o Clarification of RFC1034/1035 relating to DNSEXT ongoing work.
            + Clarification of wildcard processing rules.

          o After the work items above have been completed the working
            group will continue on reviewing the following existing
            proposed standard and examine if there is a possibility to
            progress them on the standards track.

            + RFC1995 (IXFR)  to Draft standard.
            + RFC1996 (Notify) to Draft standard.
            + RFC2136bis (Dynamic Update) to Draft Standard.
            + RFC2181 (Clarify) to IESG for advancement to Draft Standard.
            + RFC2308 (Neg Caching) to Draft Standard.
            + RFC2671 (EDNS0) to Draft Standard.
            + RFC2672 (DNAME) to Draft Standard, or revision.
            + RFC2845 (TSIG)to Draft standard.
            + RFC2930 (TKEY) to Draft standard.
            + RFC3007 (Secure Update) to Draft standard.
            + RFC3645 GSS/TSIG to Draft Standard       
            + RFC3??? AXFR clarify to Draft Standard.

          o Identify (a) method(s) to prevent the possibility of trivial
            zone enumeration.

          o Define a method for automated rollover of trust-anchors
            configured in validating resolvers.

          o Foster the development of Link Local Multicast Name
            Resolution (LLMNR) standard. The WG has taken up this work
            since LLMNR it is very similar to the DNS protocol.  LLMNR is
            targeted as proposed standard.

    The lifetime of the group is set by the work items above but while
    these are ongoing the working group has additional tasks:

          o Reviewing and providing recommendations about the
            specification, by other working groups, of RR types that do
    not
            require any special processing and that do not require any
            special naming conventions.
