PTR-Records (domain name pointer)
|
PTR-records are used to map IP addresses to domain names (reverse of A-records).
The name of a PTR-record is the IP address with the segments reversed and with "in-addr.arpa" appended to the end.
As an example, looking up the domain name for IP address "12.23.34.45" is done with a query for the PTR-record for "45.34.23.12.in-addr.arpa"
For more information see the section on Reverse Zone / "in-addr.arpa".
To create a PTR-record use one of the following options:
| · | Right-click a reverse zone in the DNS Records window, and select "New Pointer (PTR-record)" from the pop-up menu.
|
This record type is defined in RFC1035.
