What We Detect
- Hosting Provider — the company running the server (AWS, Cloudflare, GoDaddy, Hetzner, etc.)
- IP Address — the resolved IPv4/IPv6 address of the domain
- Server Location — approximate country and city of the server
- Nameservers — authoritative DNS servers (often reveal host/registrar)
- CDN Detection — Cloudflare, Fastly, Akamai, CloudFront presence
- Tech Stack — CMS, framework, analytics, and server software hints

Research Tips
- If the IP belongs to Cloudflare, the real host is hidden — check nameservers for clues
- Nameservers like
ns1.cloudflare.comconfirm CDN use;dns.squarespace.comreveals the platform - Response headers (
Server:,X-Powered-By:) often reveal server software - Combine with DNS Lookup for a full infrastructure picture
- CDN/proxy IP ≠ actual server — large sites rarely expose real IPs

Discovering Web Hosting and Infrastructure Details
Understanding who hosts a website reveals valuable intelligence about its infrastructure, reliability, and technology stack. Our hosting detection tool resolves a domain's IP address, identifies the hosting provider, checks nameserver configuration, and detects CDN usage — all from a single domain lookup. This information is essential for competitive analysis, security research, sales intelligence, and evaluating potential technology partners. Whether you are researching a competitor's tech stack, verifying a client's infrastructure before migration, or investigating a suspicious domain, hosting intelligence provides the answers.
How Hosting Detection Works
Hosting detection works by resolving a domain's DNS records, performing reverse IP lookups, and matching the results against databases of known hosting providers and IP ranges. The server's IP is mapped to an ASN (Autonomous System Number) which identifies the network owner. Nameserver patterns reveal managed DNS providers (Cloudflare, Route 53, Namecheap). HTTP response headers often expose web servers (nginx, Apache, Caddy), CDNs (Cloudflare, Fastly, CloudFront), and application platforms (Vercel, Netlify, Heroku). Our tool aggregates all these signals into a clear summary.
Infrastructure Research and Due Diligence
Before migrating a website or onboarding a new client, understanding the existing hosting setup prevents surprises. Check DNS configuration with the DNS Lookup to see all record types. Verify IP details with the IP Address Lookup. Test API connectivity with the API Request Builder. Encode webhook URLs with the URL Encoder. Explore all tools on the homepage.
