Why does the DNS provider differ from the hosting provider?

Many websites use a separate DNS service from their hosting. For example, a site might host on AWS EC2 but use Cloudflare for DNS and CDN. The tool detects each layer independently: DNS provider from NS records, hosting/CDN from CNAME records, and email from MX records.

Hosting Checker

About Hosting Checker

Identifies the hosting provider, CDN, DNS service, and email provider for any domain by analyzing its DNS records. Queries A, NS, CNAME, and MX records via Cloudflare DNS over HTTPS and matches nameserver and CNAME patterns against a database of 40+ hosting providers, CDNs, and email services. Results reveal the full infrastructure stack behind a website.

Unknown / Self-hosted
Parallel DNS queries for A, NS, CNAME, and MX records via Cloudflare DoH
Pattern matching against 25+ nameserver providers, 14 CDN/platform patterns, and 9 email providers
CNAME analysis detects platforms like Shopify, Squarespace, GitHub Pages, Netlify, Vercel
MX record analysis identifies email providers: Google Workspace, Microsoft 365, Zoho, Proofpoint
Falls back to 'Unknown / Self-hosted' with raw nameserver data when no pattern matches
No API key required — uses only public DNS infrastructure
