Every website lives on a server with an IP address. Finding it tells you where the site is hosted, which is handy before moving a site, researching a competitor, or confirming that a DNS change worked.
Step 1: Look up the IP address
Open the IP and hosting lookup, enter the domain and run it. You will see one or more IPv4 and IPv6 addresses.
Step 2: Read the owner information
- Network owner / organisation: the company that owns the IP range. It is often the hosting provider or data centre.
- Reverse DNS: a hostname such as server123.provider.com that the owner has set for the IP.
- Country: the registration country of the range (it can differ from where the server physically sits).
When the result is a CDN
Many websites use a content delivery network. In that case the IP belongs to the CDN, not to the real hosting provider. The owner will usually be a well-known CDN company. The origin server is hidden on purpose.
Other ways to find the host
- Check the nameservers with the nameserver checker. Hosts often use their own.
- Look at the MX records for the email provider.
- Check the footer or the website's legal pages.
Why people look up hosting
- To confirm a website migration has finished.
- To report abuse or a phishing site to the right provider.
- To compare hosting choices that competitors use.
- To troubleshoot a domain that points to the wrong server.
Does the IP reveal the physical location?
Only roughly, and not reliably. IP registration data shows where the owner is registered, not exactly where the machine is. Treat country as a hint.
A worked example
You look up a competitor's site and see IP 198.51.100.20, reverse DNS srv20.exampledc.net and an owner name of a data centre company. That suggests the site is on a server in that data centre, probably on a VPS or dedicated plan. If instead the owner is a CDN, you know the real host is hidden, and you can look at the nameservers and email provider for clues.
Using the information after a migration
When you move a website, compare the lookup result with the IP in your new hosting welcome email. If they match, DNS has switched. If not, either the change has not propagated yet or the A record is still wrong. See DNS propagation.
Limits to remember
- Shared servers host many sites on one IP, so the IP alone does not prove who runs a particular site.
- IPv4 and IPv6 can belong to different providers.
- Reverse DNS is optional and may be generic.
FAQ
Can two websites share one IP?
Yes. On shared hosting hundreds of sites can share an IP address.
Is it legal to look up an IP address?
Yes. The information is public by design.
