Website IP Lookup
Find the IP addresses, hosting company and CDN of any website.
How to find the IP address of a website
- Enter a domain name such as
example.com. A full web address works too. - Press Find IP.
- The tool shows every IPv4 and IPv6 address of the site, where each one is located, which network it belongs to, and which hosting company or CDN serves the site.
We ask public DNS for the site's A and AAAA records, follow any CNAME chain, and then look up each address. The same steps by hand are described in how to find the IP address of a website.
Why a website has several IP addresses
Large sites spread their traffic over many servers. DNS returns several addresses, and your browser picks one. Sites that use a CDN (content delivery network) such as Cloudflare, Fastly or Akamai show addresses of the CDN: the CDN answers visitors from a data center near them and passes requests on to the real server, whose address stays hidden.
So the location shown for a site behind a CDN is the nearest CDN data center, not the place where the site is hosted. The tool tells you when it detects a CDN.
What the results show
| Field | What it means |
|---|---|
| IP address | An address the domain points to. Click it for the full IP lookup. |
| Location | Where that address is located, as far as geolocation data knows. |
| Network | The network (ASN) that announces the address. Click it to see the network page. |
| CNAME | Another name the domain points to first, often a hint of the hosting service. |
| Name servers | The servers that hold the DNS records of the domain. |
| Hosting / CDN | The company we recognized from the network or CNAME. |
Frequently asked questions
Can I open a website by its IP address?
Sometimes. Many servers host several sites on one address and need the domain name to know which site to show, so typing the IP address often shows an error page or a different site.
Why does the IP address change?
Sites behind a CDN or a load balancer return different addresses depending on where you are and when you ask. DNS records can also be changed by the owner at any time.
How do I find the real server behind Cloudflare?
You cannot, and that is on purpose: hiding the origin server protects it from attacks. Only the site owner knows the real address.
To see all DNS records of a domain, use the DNS lookup. To check that a change has spread around the world, use the DNS propagation checker.
