The only way to ensure that the zone file of a dynamic zone is up to date is to run The incremental zone transfer (IXFR) protocol is a way for slave servers to transfer only changed data, instead of having to transfer the entire zone. These include master zones maintained by dynamic update and slave zones whose data was obtained by IXFR.

For manually maintained master zones, and for slave zones obtained by performing a full zone transfer (AXFR), IXFR is supported only if the option setup.

Update authorization is based on transaction signatures and an explicit server policy.

All changes made to a zone using dynamic update are stored in the zone's journal file.

Solaris 11 uses Image packaging system (IPS) to manage correspondences and patches.
