Description of Working Group

The DNS Incremental Transfer, Notify, and Dynamic Update Working Group is concerned with three areas of future DNS protocol development:

Incremental Zone Transfer - As the sizes of some zone files have grown quite large, it is believed that a protocol addition to allow the transfer of only the changed subset of a zone will reduce net traffic and the load on critical servers.

Change Notification - There can be large time intervals during which at least one secondary has data that is inconsistent with the primary. 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.

Dynamic Update - The need to frequently update small portions of a large zone and to have those updates propagate is perceived.
