Reverse IP Lookup: How to Find the Domain Name for an IP Address
Do you have an IP address and want to know the associated domain name? Or vice versa, do you have a domain name and want to know its IP address? You can use a reverse IP lookup tool to find out this information.
In this article, we'll explain what a reverse IP lookup is and how you can use it to find the domain name for an IP address or vice versa.
What Is a Reverse IP Lookup?
A reverse IP lookup is a way to look up who owns an IP address or domain name. It's the opposite of a forward DNS lookup, which is the process of looking up an IP address from a domain name.
With a reverse IP lookup, you can take an IP address and find out all the domain names that are associated with it. This can be useful if you're trying to track down the owner of an IP address that's been sending you spam emails, for example.
You can also use a reverse IP lookup to find out what other websites are hosted on the same IP address as a given website. This can be useful for finding out if a given IP address is hosting multiple websites, which could be an indication of a hosting company or a virtual private server (VPS).
How to Do a Reverse IP Lookup
There are multiple ways to do a reverse IP lookup. You can use a website like WhoisXML API, for example, which has a reverse IP lookup tool that you can use for free.
As you can see, this returns the domain name dns.google for the IP address 8.8.8.8.
If you want to do a reverse IP lookup for a domain name, you can use the following command:
dig -x domain.com
This would return all the IP addresses that are associated with the domain name domain.com.
