You can perform a Reverse DNS lookup, no matter what device you are currently using. Yes, you can perform a Reverse DNS lookup on Windows, Linux, macOS, or through a browser. If you choose the last option, you can technically do it through a mobile phone or a tablet without installing any additional application.
See to which domain does an IP address belongs in a fast and easy way.
Windows
On Windows, no matter if it is Windows 11, Windows 10, or older, you can use Reverse DNS lookup through the Command Prompt.
1. Click on the Start icon.
2. Type Command Prompt and open it.
3. Inside it, use the Nslookup command and the IP address that you would like to check. Type the following “nslookup 111.222.111.222” (use the IP address you would like to check).
Linux
On Linux, you can find many ways to do a Reverse DNS lookup. First, let’s open the Terminal, and then we will see 3 commands that we can use for the same purpose. You can use the one you prefer.
Nslookup command
Just like in the Windows example above, you need to type “nslookup 111.222.111.222” (use the IP address you would like to check).
Dig command
In the case of the Dig command, you have a little difference, and you need to add the option “-x” for rDNS. So, in this case, you need to type “dig -x 111.222.111.222” (use the IP address you would like to check).
Host command
The host command is also very easy to use for Reverse DNS lookup. Simply type “host 111.222.111.222” (use the IP address you would like to check).
MacOS
MacOS is very similar to Linux when it comes to commands. You can use Nslookup command, Dig command, or the Host command through the Terminal Application.
Nslookup command
Type “nslookup 111.222.111.222” (use the IP address you would like to check). You will see the corresponding domain to the IP address.
Dig command
1. Dig command is a great tool that is pre-installed on your macOS device.
2. Now that you have it, just type “dig -x 111.222.111.222” (use the IP address you would like to check).
Host command
The same as in Linux, you can type ““host 111.222.111.222” (use the IP address you would like to check).
Reverse DNS lookup via a web browser
You can do a Reverse DNS lookup through any browser on any OS or device. So here you have a few options.
WhatIsMyIP
You can use WhatIsMyIP to check an IP address online and see to which domain it belongs. Also, it has a short description of what a Reverse DNS lookup is. When you put an IP address, it will directly show you the domain name.
MXtoolbox
MXtoolbox has a bit better result. It will show you more information about the PTR record and from which name server the information came. You can use the page for probing other DNS records.
DNSChecker
DNSChecher is very similar to WhatIsMyIP in the way it displays the result – just the domain name. Again you will see a nice description of Reverse DNS and PTR records.
Conclusion
Now you know how to do a Reverse DNS lookup, no matter what device you are using right now. So go on and try it out. Find the best method for you.
