-        BIND supports Incremental Zone Transfers (IXFR), where a slave nameserver only downloads the updated portions of a zone modified on a master nameserver. The standard transfer process requires that the entire zone be transferred to each slave nameserver for even the smallest change. For very popular domains with very lengthy zone files and many slave nameservers, IXFR makes the notification and update process much less resource-intensive.
+        Through the use of the <command>view</command> statement in <filename>named.conf</filename>, BIND can present different information depending on which network a request originates from.

+        This is primarily used to deny sensitive DNS entries from clients outside of the local network, while allowing queries from clients inside the local network.

-        Note that IXFR is only available when using <firstterm>dynamic updating</firstterm> to make changes to master zone records. If manually editing zone files to make changes, Automatic Zone Transfer (AXFR) is used. More information on dynamic updating is available in the <citetitle>BIND 9 Administrator Reference Manual</citetitle> referenced in <xref linkend="s2-bind-installed-docs" />.<!-- RHEL5:  .
