Domain Hosting Checker

Find out which hosting provider and network a domain uses

What is a Domain Hosting Checker?

A domain hosting checker reveals which hosting provider or network a website is running on by resolving its IP address and looking up the network owner.

How to use it

Enter a domain and click Check. The tool resolves the A record, then looks up the ISP and organization of the IP.

  • The result shows the IP address and its network owner.
  • ASN identifies the hosting provider or CDN.

Tips

Knowing a competitor's hosting provider can help you compare performance options.

Frequently Asked Questions

How is hosting detected?+
The domain's A record is resolved to an IP address, then the network owner of that IP is looked up — that reveals the hosting provider.
What if the domain uses a CDN?+
