DNS IXFR, Notification, and Dynamic Update (DNSIND) Charter


Mailing List Information

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.
