Reverse DNS Lookup tool in windows. Windows is the most used OS in the world. It comes with some built-in tools which many of the users don’t know about. In windows you can perform reverse DNS lookup of any IPv4 address using pre-installed tools.
- Open up the CMD (Command Prompt)
- Type the following command.
ping -a IP_address_here
In the output of these commands you will see the results of the reverse DNS lookup.
What is Reverse DNS Lookup Tool
Reverse DNS lookup is the opposite of the DNS lookup. It works the opposite way of the DNS lookup. DNS lookup gets the IP address of the target domain.
On the other hand reverse DNS lookup gets the domain name from the target IP address.
If you perform the DNS lookup on google.com, you will get the IP address (18.104.22.168). But if you perform reverse DNS lookup on 22.214.171.124 you will get the domain name connected to this IP address. You may not get the domain addresses for every IP address because not every IP is connected to the domain name.
IPv4 Reverse DNS Lookup
In IPv4 address special domain name is used like this in-addr.arpa. This domain name used to concatenate with the IPv4 address. If you query rDNS of this IP address(126.96.36.199), you will see something like this in the output: 188.8.131.52.in-addr.arpa which means its an IPv4 address.
Instead of the IP address this concatenated string will be looked up to find the domain name pointing to this IP address. It is to be noted that without concatenating the special domain name with IP address, we can’t find the domain name pointing to the target IP address.
IPv6 Reverse DNS Lookup
In IPv6 address special domain name is used like this ip6.arpa. This domain name used to concatenate with the IPv6 address. If you query rDNS of any IPv6 addres, you will see something like this in the output: c.b.184.108.40.206.2.X.220.127.116.11.18.104.22.168.0.0.0.0.0.0.0.0.8.b.d.0.6.0.1.0.ip6.arpa which means its an IPv6 address.
The other method of querying the domain from this concatenated string is very similar to the IPv4 reverse lookup.
