Incremental Zone Transfer
According to RFC 1995, incremental zone transfer (IXFR) is a
mechanism for slave servers to transfer only the changed data, instead of
transferring the entire zone every time the zone data changes.
When acting as a master, BIND 9.2.0 supports IXFR when the necessary
change history information is available in the zones. The change history
includes master zones maintained by dynamic updates and slave zones
whose data was obtained by IXFR. It does not support IXFR for
manually maintained master zones and slave zones obtained by zone
transfer (AXFR).
