Free Website Hosting Checker — Find Out Who Hosts Any Website

What Is a Website Hosting Checker?

A website hosting checker identifies the hosting provider behind any website. By analyzing DNS records, IP addresses, and server information, this tool reveals which company is hosting a site — whether it's AWS, Cloudflare, GoDaddy, Bluehost, DigitalOcean, or any other provider.

Our free tool lets you instantly discover the hosting company, server IP, and nameservers for any domain — useful for competitive research, migration planning, and troubleshooting.

Why Check Website Hosting?

Knowing who hosts a website is valuable for several reasons:

• Competitive Research — Discover what hosting stack your competitors use and how it affects their performance
• Migration Planning — Evaluate hosting alternatives by seeing what successful sites in your niche use
• Sales & Outreach — Web hosting and agency professionals can identify potential clients on specific platforms
• Troubleshooting — Identify hosting-related issues by knowing the provider's infrastructure
• Security Research — Trace the origin of suspicious websites or phishing domains

Frequently Asked Questions

How does the website hosting checker work?

The tool performs DNS lookups to find the domain's IP address and nameservers, then cross-references the IP against known hosting provider IP ranges and ASN databases. It also checks WHOIS data and reverse DNS to identify the hosting company.

Can I check who hosts a website using Cloudflare?

When a website uses Cloudflare as a CDN/proxy, the hosting checker will show Cloudflare's IP addresses. The actual origin hosting provider is hidden behind Cloudflare's network — this is by design for security. The nameservers will show as Cloudflare nameservers.

Is the hosting information always accurate?

The tool provides the most accurate information available from public DNS and IP records. However, websites using CDNs, reverse proxies, or multi-cloud setups may show the CDN provider rather than the origin host. For most websites, the results are highly accurate.

Why would I need to know who hosts a website?

Common reasons include competitive research (seeing what fast sites use), investigating suspicious domains, planning a hosting migration, evaluating hosting options, and sales prospecting for hosting or web development services.
