Network tools

Check your IP address and VPN, and look up any domain or network.

Everyday network checks in one place

See your public address, internet provider and connection details with What Is My IP, find your lowest-ping gaming region with the Game Server Ping Test, and make sure your VPN isn't exposing your real address with the VPN Leak Test.

For websites and networks, the DNS Lookup shows a domain's records, the WHOIS Lookup shows who registered it and when it expires, and the Subnet Calculator works out IPv4 and IPv6 address ranges. Nothing you check is stored.
