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).
