IP address lookup and network diagnostics

Start with your public IP

ABPing shows the address used to reach this site and the results of configured IP probes. You can also look up a public IP for location, network and ASN information from DB-IP Lite.

IP location is a database estimate. A network label or list match provides context about an address; it does not prove who is using it or whether a connection is safe.

Choose a check for the question you have

Use WebRTC to inspect browser connection candidates, or the basic DNS test to observe resolvers reported by four third-party sources. Target exit checks, HTTP connectivity checks and a manual speed test add other views of your connection.

The current IP and configured IP probes load when you open the home tool. Other checks start when you choose to run them. Third-party tests make requests to their providers, which can see the connection reaching them.

Compare before and after a network change

Save a baseline, change your connection, and run the relevant checks again. The comparison separates observed changes from failed, incomplete and not-yet-retested items.

The baseline stays in the current browser tab session; if browser storage is unavailable, it remains only in the current page. Reports can be downloaded locally. Review the visible addresses and hostnames before sharing a file.
