Type a hostname or paste a link to see the IP addresses it points to.
How it works
Every website or server name (like example.com) points to one or more IP addresses through DNS. This tool asks DNS for them: IPv4 (A records) and IPv6 (AAAA records).
Big sites often return several addresses, and they can change over time. The TTL shows how long an answer may be cached.
Handy when an app asks for a server, proxy or SNI host as an IP address instead of a name.
We only look the name up in DNS; nothing connects to the site. The hostname and the IPs it points to are remembered (never who looked it up) so IP to Hostname can show which websites use an IP, which means anyone can see it there: don't look up private names. IPs on your own connection and dynamic-DNS names are never remembered.
