Your public IP address

Show my public IP address

The address above is the public IP through which your connection reaches ipcheck.tools. With a VPN, proxy or company network, it may belong to that service's internet connection. It identifies a connection or intermediary, rather than reliably identifying one person.

Why are my public and local IP addresses different?

Your computer might use 192.168.1.20 on Wi-Fi. With IPv4, a router often translates this local address into a public address. Your provider may apply another translation. An IPv6 device can have several addresses. A public IPv4 address, a global IPv6 address and the local router address therefore serve different purposes.

The IPv4 and IPv6 displays also check those connection paths through external IP requests. A missing result or an error does not by itself prove that internet access is unavailable: browser filters, a VPN or an unreachable lookup service can affect detection. Separate connections may take different paths.

What do the provider, ASN and location tell me?

Provider, ASN and location information comes from IP databases. A city may represent a network node or provider location, rather than a precise home address. This is separate from browser location permission. To investigate another public address, use the IP lookup; for its AS number, use the ASN lookup.

Which check should I use next?

• Find your IP on Windows, macOS and Linux: distinguish a local address from your public internet connection.
• TCP ping check: test a connection to a public target port from Düsseldorf.
• Online traceroute: view responding hops between our server and your target.
• DNS leak test and WebRTC check: interpret additional observations from your browser.

A successful server check confirms the path from the measurement server to the target. To diagnose a problem on your Wi-Fi, also test directly on your device.
