IP & Hosting Lookup

What can you learn from an IP address?

Every website runs on a server with an IP address. Looking it up shows where the site is hosted, which company owns that network, and whether a domain really points to the server you expect. It is a quick check after moving hosting, when setting up DNS records, or when investigating a suspicious website.

• Confirm a migration: check that the domain now resolves to your new server's IP.
• Identify the host: the network owner and reverse DNS usually reveal the provider.
• Troubleshoot DNS: compare with the A records on the DNS lookup page.

Frequently asked questions

How do I find the IP address of a website?

Enter the domain name in the tool above. It resolves the domain to its IPv4 and IPv6 addresses, the same way a browser does.

How can I tell who hosts a website?

Look at the network owner and the reverse DNS name of the IP address. They usually show the hosting company or data centre that runs the server.

Why does a website have several IP addresses?

Large sites use several servers or a CDN for speed and reliability, so the same domain can resolve to more than one IP.

What is reverse DNS?

Reverse DNS (a PTR record) maps an IP address back to a hostname. Hosting providers often set it to the server name.
