PTR Record Lookup

whatsmydns.net PTR Record Lookup tool lets you query DNS servers and get instant results.

Reverse DNS or PTR record lookups are used to determine the PTR records associated with a domain.

Looking for easier to understand results? Use the Global DNS Checker tool.

DNS PTR Record

PTR records, known as Pointer records or reverse DNS records are used to store the domain name for an IP address.

PTR records are the inverse record of both A records for IPv4 addresses, and AAAA records for IPv6 addresses.

PTR records are stored as their IP address broken into segments and then reversed, followed by either .in-addr.arpa. for IPv4 records or .ip6.arpa. for IPv6 records. For example the IP address 192.168.2.1 would be stored in 1.2.168.192.in-addr.arpa..

The Reverse DNS Lookup tool allows you to analyse domain name and IP address configurations in a more comprehensive way than a simple PTR record lookup.

You can use the Reverse DNS Generator to convert IP addresses into the correct format for PTR records.

Example PTR record

An example PTR record may look like the following:

Record Type Value TTL
1.2.168.192.in-addr.arpa. PTR example.com 3600

1.2.168.192.in-addr.arpa. represents identifier of the record. This is the record name for the IPv4 A record 192.168.2.1.

PTR is the record type.

example.com is the value of the record.

3600 is the TTL (time to live) of the record in seconds, this example represents 1 hour. This means that when a record has had updates made to it, then it will take 1 hour to update.

IPv6 PTR Records

Record Type Value TTL
1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.8.e.f.ip6.arpa. PTR example.com 3600

1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.8.e.f.ip6.arpa. represents identifier of the record. This is the record name for the IPv6 AAAA record fe80::1.

PTR is the record type.

example.com is the value of the record.

3600 is the TTL (time to live) of the record in seconds, this example represents 1 hour. This means that when a record has had updates made to it, then it will take 1 hour to update.
