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.
