named.rev -- reverse hosts database file

Format

$INCLUDE named.soa

name  [ttl]  class  PTR  host.

Description

The named.rev file contains the zone database for the IN-ADDR.ARPA domain. This file name is arbitrary; it can be specified in /etc/named.conf in the file substatement of the appropriate IN-ADDR.ARPA zone statement.

The pointer records are needed by gethostbyaddr(SLIB).

It is created manually on the primary server. Its entries are:

   $INCLUDE named.soa
   ;name   {ttl}   class   type    real_name
   0.130           IN      PTR     host1.company.COM.

name: is the IP address of the host in reverse order. You only need to specify enough octets to make the name unique. For example, host1 could have the address 128.32.130.0.
real_name: is the name of the host to which the index points. There should be an entry for each host listed in named.hosts. The trailing `.' prevents DNS from appending the current $ORIGIN.

Example

$INCLUDE named.soa

2.130 IN PTR host1.company.COM. 3.0 IN PTR host2.company.COM. . . . . . .
