Reverse IP lookup
Reverse IP lookup requests the hostname for an IP address. Inspect reverse DNS results and understand why this does not list every website on a server.
What is Reverse IP lookup?
Reverse IP lookup requests a hostname associated with an IP address through reverse DNS. It helps you examine the name returned for a network address when reviewing logs or checking a connection. This tool does not search for every website sharing the same hosting infrastructure.
How to use this tool
Enter a valid IP address and submit the lookup. Compare the returned hostname with the network or service you expected. If the tool initially shows your connection address, replace it when your investigation concerns a website's server or another known public address.
Understanding the results
The lookup uses the address's reverse DNS response. The network operator controls that mapping, and it can differ from the domain visitors use to reach a website. A missing name or an unchanged address can mean that no usable reverse name was returned. Shared servers, proxies, and CDNs also make it inappropriate to infer a complete site inventory from one reverse DNS name.
Frequently asked questions
Is this a shared hosting discovery tool?
No. It performs a reverse hostname lookup. It does not enumerate neighboring domains, customers, or all websites hosted on a shared address.
Should the reverse name match my domain?
Not always. Providers often publish an infrastructure hostname for an address. Whether a specific reverse name is required depends on the service you are configuring.
