Sample named.local file

named.local(SFF) specifies the PTR record for the loopback interface, localhost, whose network address is 127.0.0.1. The PTR record, which should point back to the localhost name for the given zone, is vital if you want users to be able to use hostname authentication via hosts.equiv or .rhosts on the name localhost. The name of this PTR record is always 1.0.0.127.in-addr.arpa.
