named.rev(4tcp)


named.rev -- IN-ADDR.ARPA database file

Synopsis

$INCLUDE named.soa

name [ttl] class PTR real_name.

Description

The named.rev file contains the zone database for the IN-ADDR.ARPA domain. The actual filename is arbitrary; it is normally specified in named.boot as the source file for each IN-ADDR.ARPA domain.

Pointer records (PTR) are needed to convert IP addresses to hostnames, for example using gethostbyaddr(3N). See named.hosts(4tcp) for a description of these records.

The entries are:

name
The IP address of the host in reverse order. Only enough octets need to be specified to make the name unique within the zone.

real_name
The name of the host to which the index points. There should be an entry for each host listed in the named.hosts(4tcp) file. A trailing ``.'' prevents DNS from appending the current $ORIGIN.
See named.local(4tcp) for a description of the PTR and A records that are needed for the local loopback interface, localhost.
