These files can have different names or be placed in different directories. If you have only a single zone, one named.rev file is all that's needed.<BR><P>The named.local file contains an entry for the loopback driver (which always has the IP address 127.0.0.1). This file must contain information about the IN-ADDR-ARPA mapping of the loopback driver, as well as a domain again (because the named.rev file doesn't cover the 127 subnet).
