Find your private IP address
Your private IP address (also known as internal IP, intranet IP, or local IP) is the IP address that identifies your device on your local network (LAN). This address is not used on the Internet and, as a rule, is not transmitted outside of your LAN.
However, even if this IP address should remain private, there are some techniques allowing remote webpages to find your private IP address. For example, this webpage uses WebRTC to open a peer-to-peer connection and extract your private IP address. This does not work in all browsers, as some do not support WebRTC, and some care about the users’ safety. In any case, you should be happy if your private IP cannot be detected.
