Reverse IP Lookup
Use Reverse IP Lookup to look for a host name associated with an IP address. Review the result, understand its limits, and continue your network checks.
Reverse IP Lookup for an associated host name
Reverse IP Lookup starts with an IP address and attempts to return an associated domain or host name. It can help you add context to an address found while troubleshooting a server or reviewing a network record.
How to use Reverse IP Lookup
- Enter the address in the IP field.
- Select Submit to perform the lookup.
- Read the host name in the Result field, when one is returned.
- Use Copy to clipboard if you need to include the result in your troubleshooting notes.
What a reverse lookup tells you
A reverse lookup asks for a name associated with an address, while a forward DNS lookup starts with a name and looks for its records. These are different checks, so a reverse result may not match the domain you originally visited.
The returned name can describe network infrastructure instead of a customer-facing website. An address may also be shared by multiple services. Use this tool to investigate a host association, not to produce a complete inventory of every website on a server.
When no useful name is returned
Not every address has a helpful reverse DNS name. An empty result or an address returned unchanged does not establish that the address is invalid or that no website uses it. Confirm the input and compare it with other network evidence.
Reverse IP Lookup questions
Will it find every domain hosted on an IP?
No. This tool attempts to find an associated host name. It should not be treated as a complete shared-hosting domain search.
Does the name prove ownership?
No. A host association alone does not establish who owns a website, who uses a connection, or whether a service is trustworthy.
Can I verify the returned host?
Check its forward DNS records and compare the returned address with your original input. Additional verification may be needed for your particular network investigation.
Continue your network checks
Use DNS Lookup to inspect the returned host's records, IP Lookup for approximate address location details, and SSL Lookup to review a website host's certificate.
