Web Hosting Checker
Want to find out who is hosting a website? Use this free web hosting checker to instantly detect hosting provider, CDN, and infrastructure details.
About This Tool
The Web Hosting Checker tool helps you find out who is hosting any website using advanced infrastructure analysis. It identifies the server IP address, infrastructure organization, ASN (Autonomous System Number), server location, and possible CDN usage.
Unlike basic hosting checkers that rely only on nameservers, this tool performs ASN-based infrastructure lookup and reverse DNS analysis to improve detection accuracy — even when the hosting brand operates under a parent company.
This tool allows you to:
- Identify the hosting provider behind a domain
- Detect infrastructure organization (e.g., Unified Layer, AWS, etc.)
- View ASN (Autonomous System Number)
- Check server location and reverse DNS
- Detect CDN masking such as Cloudflare
- Understand hosting ownership structure
Hosting analysis is performed using real-time DNS and infrastructure lookups. No domains are stored, logged, or shared.
Frequently Asked Questions
How can I find out who is hosting a website?
Enter the domain name into this tool. It analyzes IP address, ASN, and infrastructure data to identify the hosting provider.</p>
Is hosting detection always accurate?
While ASN-based detection improves accuracy, some websites use CDN masking or reseller infrastructure which may hide the original host.</p>
What is ASN in hosting?
ASN (Autonomous System Number) identifies the network responsible for managing an IP address range. It helps detect infrastructure ownership.
Can a website hide its hosting provider?
Yes. Websites using services like Cloudflare may mask their origin server. In such cases, only the CDN layer may be detected.</p>
