Why does Cloudflare show as the host?
If a website uses Cloudflare's CDN, DNS resolves to Cloudflare's edge servers. The actual origin host is hidden behind the Cloudflare network.
What is a hosting provider vs a domain registrar?
A domain registrar is where you purchase and manage your domain name (e.g., Namecheap, GoDaddy). A hosting provider stores your website files on a server and makes them accessible online. They can be the same company or different ones.
What is WHOIS and how does WHOIS lookup work?
WHOIS is a public database of domain registration records maintained by ICANN. Our WHOIS lookup queries this database to show domain registration date, registrar, expiry date, and domain age.
How do I find the IP address of a website?
Use our IP address lookup — enter the domain to see IPv4 (A record) and IPv6 (AAAA record) addresses with geolocation and hosting provider identification.
What are nameservers and MX records?
Nameservers are DNS servers that store all DNS records for a domain — incorrect settings can take a website offline. MX records specify which mail server handles email for a domain. Our DNS lookup tool shows all record types.
How do I check if a website uses Cloudflare?
Enter the domain into our hosting checker. If nameservers end in .ns.cloudflare.com and the IP belongs to Cloudflare's range, the site uses Cloudflare CDN.
Can I check the hosting of any website worldwide?
