DNS IXFR, Notification, and Dynamic Update (dnsind)
Note: The data for concluded WGs
is occasionally incorrect.
Description of Working Group
The DNS Incremental Transfer, Notification, and Dynamic Update Working
Group is concerned with three areas of future DNS protocol
1. Incremental Zone Transfer - As the sizes of some zone files have
quite large, it is believed that a protocol addition to allow the
transfer of only the changed subset of a zone will reduce net
and the load on critical servers.
2. Change Notification - There can be large time intervals during which
at least one secondary has data that is inconsistent with the
The proposed ``notify'' mechanism (where the primary sends a message
to known secondaries) facilitates fast convergence of servers
vis-a-vis consistency of data in the zones.
3. Dynamic Update - The need to frequently update small portions of a
large zone and to have those updates propagate is perceived.
Goals and Milestones
