named.local -- local loopback interface file

Format

$INCLUDE named.soa


1  [ttl]  class  PTR localhost.

Description

The named.local file specifies the PTR record for the local loopback interface whose network address is 127.0.0.1. This file is referenced in the file substatement of the 0.0.127.IN-ADDR.ARPA zone statement in /etc/named.conf. It is vital to the proper operation of every name server that the 127.0.0.1 address have a PTR record pointing back to the local host. As implied by this PTR record, there should be an A record in named.hosts specifying that the local host has an IP address in the IN-ADDR.ARPA domain.

The pointer records are needed by gethostbyaddr(SLIB).

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

   $INCLUDE named.soa
   ;name   {ttl}   class   type    real_name


   1               IN      PTR     localhost.

name
is always `1'.

real_name
is the name of the local host. The trailing period (.) prevents DNS from appending the current $ORIGIN.
