Inspect an address, calculate a subnet, query public DNS or check WireGuard configuration syntax. Each tool explains its inputs, results and data boundary.

IP classification, CIDR calculations and WireGuard syntax checks run in the browser; DNS lookup queries a public resolver.
IP classification, CIDR calculations and WireGuard syntax checks run locally. DNS lookup queries a public resolver and does not test device DNS leaks.
