DNS Extensions (dnsext) ----------------------- Charter Last Modified: 2006-03-30 Current Status: Active Working Group Chair(s): Olafur Gudmundsson Olaf Kolkman Internet Area Director(s): Jari Arkko Mark Townsley Internet Area Advisor: Mark Townsley Mailing Lists: General Discussion:namedroppers@ops.ietf.org To Subscribe: namedroppers-request@ops.ietf.org Archive: http://ops.ietf.org/lists/namedroppers/ 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.
