PTR Generator
Convert an IPv4 or IPv6 address to its reverse-DNS owner name and optionally format a PTR record.
This tool handles input and primary processing in your browser and is designed not to send the input to QuickKit’s server.

PTR record
How it works
A PTR owner name is deterministic: IPv4 octets are reversed under in-addr.arpa, while all 32 IPv6 hexadecimal nibbles are reversed under ip6.arpa. This tool does not perform a DNS lookup or verify that a record exists.
