Free Bulk Domain to IP & Hosting Lookup
Find out where websites live: their IP addresses, the hosting company or CDN behind them, the network and country, and who runs their DNS and email. Check up to 50 domains or IP addresses at once.
Quick human check, then the tool unlocks:
What you get
- IP addresses (IPv4 and IPv6) the domain points to, and any alias (CNAME).
- Reverse DNS: the server name behind each IP, often revealing the host.
- Network and hosting company: the ASN, the organisation that owns the IP range, and its country. Well-known hosts and CDNs such as Cloudflare, AWS, Google, GoDaddy and Bluehost are named.
- DNS provider from the name servers, and email provider (Google Workspace, Microsoft 365 and others) from the mail servers.
If a site uses a CDN or protection service such as Cloudflare, you see the CDN, not the real server behind it. That is by design.
🔒 The domains you check are not saved or logged. IP addresses are looked up in Team Cymru's public network database.
