IP Address Tool is a free Chrome extension developed by JordanTBH Technologies. As the name suggests, it allows users to check their IP address, proxy IP, proxy host, and other additional information without opening an additional tab. The extension is currently available in English, English (GB), English (US), French, and Spanish, with plans to add more languages in future releases.

One of the key features of IP Address Tool is that it does not open any additional tabs, resulting in lower CPU usage. The IP address updates every 5 minutes and the extension provides alerts for when the IP address changes. Users can hover over the extension for even quicker viewing of their IP information.

The extension also offers a convenient "+1" button for users to show their appreciation and share it with others. Additionally, users can follow the developer's blog to stay updated on the latest news and updates before they are live on the Chrome web store.

Overall, IP Address Tool is a handy extension for quickly checking IP address and proxy information without the need for additional tabs.
