Find Website IP Address

Find a Website's IP Address

Enter a domain and this tool looks up its A records through public DNS, then lists the IPv4 addresses the domain points to. Busy sites often return several addresses, and the list may change between lookups as the site spreads load across servers.

How Domains Map to IPs

1. DNS does the translation: your browser asks a resolver for the domain's A record (IPv4) or AAAA record (IPv6), then connects to the address it gets back.
2. Many sites share one IP: shared hosts and CDNs serve thousands of domains from the same address. The server reads the hostname the browser sends to decide which site to return.
3. CDNs hide the origin: a site behind Cloudflare, Fastly or CloudFront returns the CDN's edge addresses, not the address of the server that holds the site.
4. Results depend on location: some DNS providers return different addresses depending on where the query comes from, so you may see other IPs from your own network.

Other Ways to Look It Up

• dig (macOS, Linux): dig +short example.com A, and dig +short example.com AAAA for IPv6.
• nslookup (Windows, macOS, Linux): nslookup example.com
• ping: ping example.com prints the address it resolved first, even when the host blocks ping replies.

To see which network owns an address, paste it into the IP WHOIS lookup. To compare answers from resolvers around the world, use the DNS propagation checker.
