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.
