Perform Reverse DNS Lookup
With our reverse IP lookup, you can easily perform a reverse DNS lookup to discover the domain name of an IP address. If you have an IP address and you want to see which domain it belongs to, you can enter it into our tool.
A reverse DNS lookup is the opposite of a normal DNS lookup. Instead of resolving a domain name to an IP address, the reverse DNS process resolves the IP address to a domain name.
How Does Reverse DNS Tool Work?
The functionality of our reverse DNS tool is simple and straightforward. All it requires you to do is put an IP address into the provided space. After that, you have to click on the “Find” button.
Once the lookup process ends, you will be able to see the domain name associated with the IP address.
How Does Our Reverse IP Tool Find the Domain Name from the IP Address?
The process of reverse DNS lookup works on the basis of the PTR record.
The PTR record (or “pointer” record) is a DNS record that maps a domain name to an IP address. It essentially performs the opposite function of an A record.
Reverse DNS lookup only works if the domain in question has a PTR record configured for it. If there is no PTR record, the reverse IP lookup will return with an error.
Frequently Asked Questions
How do I add a PTR record for my domain?
You can add a PTR record for your domain by visiting your domain registrar’s website and using the control panel. For many domain registrars, the control panel of choice is the cPanel. In cPanel, you can find the options to add or edit DNS in the Zone Editor.
What is the meaning of forward DNS lookup and reverse DNS lookup?
Forward DNS lookup refers to the normal DNS lookup in which an IP address is discovered for a domain name. In a reverse DNS lookup, on the other hand, a domain name is discovered for an IP address. For the forward DNS lookup, the A record is used, while for the reverse DNS lookup, the PTR record is used.
What is the practical use of reverse DNS lookups?
Reverse DNS lookup is used by email clients to check the IP in the incoming email message. This helps them understand which host is sending the message and whether they are reliable or not.
