Domain → IP
Resolve any domain to its IPv4 and IPv6 addresses.
About the Domain to IP Tool
The Domain to IP tool resolves any domain or hostname to its A (IPv4) and AAAA (IPv6) records. It's the most basic and most-used DNS lookup — the answer to 'what IP does this website live on?' Whether you're setting up firewall rules, allowlisting an origin server, verifying a CDN switch, debugging a WAF or investigating an outage, this is the tool you reach for first.
Because many high-traffic sites use CDNs, cloud load balancers or geo-DNS, a single domain often resolves to a different IP depending on where the query comes from. This tool queries from Cloudflare's edge network so the answer reflects a fast, well-connected vantage point — useful for confirming that a change has taken effect at the CDN level. For a full geographic view use the Propagation Checker instead.
Both IPv4 and IPv6 answers appear side by side, so it's easy to spot when a domain is IPv6-ready or when it's fallen back to IPv4-only. That matters for compliance in some markets and for reachability from IPv6-only networks such as mobile carriers.
