Create PTR records for IPv4 and IPv6 addresses

January 3, 2019
Contributed by:  C

A pointer (PTR) record translates an IP address to its domain name. IPv4 PTR records are represented by the octets of an IP address in reverse order with the string “in-addr.arpa.” appended at the end. For example, the PTR record for the IP address 1.2.3.4 is 4.3.2.1.in-addr.arpa.

IPv6 addresses are reverse mapped under the domain IP6.ARPA. IPv6 reverse-maps use a sequence of nibbles separated by dots with the suffix “.IP6.ARPA” as defined in RFC 3596. For example, the reverse lookup domain name corresponding to the address, 4321:0:1:2:3:4:567:89ab would be b.a.9.8.7.6.5.0.4.0.0.0.3.0.0.0.2.0.0.0.1.0.0.0.0.0.0.0.1.2.3.4.IP6.ARPA.

Add a PTR record by using the CLI

At the command prompt, type the following commands to add a PTR record and verify the configuration:

-  add dns ptrRec <reverseDomain> <domain> [-TTL <secs>]
-  show dns ptrRec <reverseDomain>

Example:

> add dns ptrRec 0.2.0.192.in-addr.arpa example.com
 Done
> show dns ptrRec 0.2.0.192.in-addr.arpa
1)      Reverse Domain Name : 0.2.0.192.in-addr.arpa
        Domain Name : example.com               TTL : 3600 secs
 Done

To remove a PTR record, type the rm dns ptrRec command and the reverse domain name associated with the PTR record

Add a PTR record by using the GUI

Navigate to Traffic Management > DNS > Records > PTR Records and create a PTR record.
