IP Address Checker
Enter a domain to resolve its IPv4 and IPv6 addresses via real DNS resolution.
How this works
This tool performs a real DNS lookup for the domain you enter, using Node's own built-in DNS resolver — no third-party IP-lookup API, paid or free. It asks for A (IPv4) and AAAA (IPv6) records separately and shows exactly what DNS returns, with no invented fallback if a record type isn't found.
Frequently Asked Questions

- No — a successful DNS resolution confirms the domain resolves to an address, not that the site is currently reachable.
- Does it show both IPv4 and IPv6?
- Yes, both A and AAAA records are resolved and shown separately.
