PTR Records

Pointer records (PTR) are used for reverse lookups.  For example, to make 192.168.0.1 resolve to www.yourdomain.com, the record would look like:

1.0.168.192.in-addr.arpa  PTR  www.yourdomain.com.

Note: The IP address is reversed in the first field.  Please use a period after your hostname (second field).

The “in-addr-arpa” method is the most frequently used.

Important: PTR records are effective only if your site has its own IP address.

Important:

PTR records are only effective if named.conf is manually edited and the proper zone information is added.  This can only be done by a root user (the server Admin).
