Reverse IP Lookup
The Reverse IP Lookup tool finds all the domains and subdomains that resolve (or have resolved) to a given IP address.
How to use it?
Enter an IPv4 or IPv6 address in the search bar and run the query. You can try a sample query.
The results list all domains pointing to that IP, including the DNS record type (A or AAAA) and timestamps.
What can I use it for?
The tool answers the question "what else lives on this IP?". It's mostly used to see which other sites share a server, or, during a security assessment, to find extra targets sitting on the same infrastructure as your main one. On a single IP it also doubles as a virtual-host enumeration.
You can also use the hosts search with the resolution field to achieve similar results with more filtering options, e.g. resolution:"104.16.*".
How many credits does it cost?
Each search you run spends 1 credit (see Credits). Results are paginated (30 per page).
