- Description of Working Group:
- The DNS Working Group is concerned with the design, operation, and
- evolution of the Domain Name System within the Internet. As the Internet
- continues to grow, we expect to serve as a focal point for work on scaling
- problems within the current framework, work on protocol evolution as new
- mechanisms become necessary, and documentation of current practice for DNS
- implementors and administrators. We are also responsible for oversight of
- DNS activities by other groups within the IETF to the extent that we
- review the impact such work will have on the DNS and make recomendations
- to the working groups and IESG as necessary. Since some of these are
- ongoing tasks, we do not expect the working group to disband anytime soon.
-
- Several issues are of particular concern at this time:
-
- Scaling. The DNS is the victim of its own success. The global DNS
- namespace has grown to the point where administering the top levels of
- the tree is nearly as much work as the old NIC host table used to be.
- We need to work on ways to distribute the load. Some of the solutions
- are likely to be technical, some political or economic; we still treat
- the top-level DNS service the way we did when DARPA was footing the
- bill, and the funding for that service is in the process of going away.
-
- Security. The DNS is a zero-security system; it is not even as
- strong as the IP layer above which it operates. As a result,
- accidental spoofing (cache pollution) is an all-too-frequent occurance.
- We need to make the DNS more robust against accidental corruption, and
- must provide at least an optional authentication mechanism for that
- portion of the community that wants one. At the same time, we must not
- cripple the existing system by drasticly increasing its bandwidth
- consumption or by mandating use of cryptographic techniques that would
- preclude worldwide distribution of DNS software. The global DNS
- database is exactly that, an existing world-wide database representing
- hosts on six continents and (at least) forty-five countries. A
- solution that does not take this into account is not acceptable.
-
- Management. We have a draft document describing MIB extensions to
- manage the DNS. We also need to specify a standard way to dynamically
- create and destroy DNS records; SNMP may be an appropriate tool for
- this task, but we haven't yet specified enough of the details to know
- for certain. We need to examine the impact that a dynamic update
- mechanism will have on the DNS, with particular attention to security
- and scaling issues.
-
- IPv7/Routing. As the fur starts flying in the battle between the IPv7
- proponants and the new-routing-architecture proponants, we expect that
- groups on both sides will need some amount of support from the DNS.
- Such support is likely to be minimal and straightforward, but these
- proposals are likely to need "rush service" for whatever support they
- require. So the working group needs to monitor these activities, stay
- involved, and generally do what it can to make sure that DNS support is
- not a bottleneck.
-
- We also need to examine the impact that any proposed IPv7 system would
- have on the DNS, since the DNS database and protocols have special
- provision for IP addresses.
-
-
