What Is A Reverse PTR Record?


PTR record or more appropriately a reverse PTR record is a process of resolving an IP address to its associated hostname. This is the exact opposite of the process of resolving a hostname to an IP address. Example, when you ping a name mail.somedomain.com it will get resolved to the ip address using the DNS to something like 192.168.1.5. Reverse PTR record does the opposite; it looks up the hostname for the given IP address. In the example above the PTR record for IP address 192.168.1.5 will get resolved to mail.somedomain.com.
