Network & IP Tools - IPAddress.to von IPAddress.to

This tool uses IPAddress.to and allows you to check your own IP and also the IP and network details of the site that you're visiting.

You're also able to right-click on domains and IPs and do a lookup on those as well.

For your privacy, it only loads when you open the extension so it doesn't require permission for all sites, but it does make external requests to IPAddress.to.
