Once you connect your computer device to a router with default settings, it will automatically assign you a local IP address. Unlike public IP addresses that are traceable, it is not easy to get Local IP address as it is hidden from the external world and is used specifically in your private network.
Once your router connects (your modem, wifi network access point, etc..)to the internet through your ISP, it conveys internet activity to all the devices connected to the router. This forms the Network Address Translation (NAT) process. This is where the router converts your local private IP into a public IP when sending traffic over the internet. When you receive traffic, the Router will then reverse the Public IP to a private IP. This demonstrates that your Local IP is visible to you, your router and your network. It is your private ID. If anyone know your public IP, it is mean that your router IP, location, ISP is known. But they can not know which device exactly you are using behind your public IP. To know that,they need your local IP, or MAC address. So question is how do you get local IP address via browser? Answer: WerbRCT
The createOffer method creates the generation of a Session Description Protocol (SDP). This provides any information about media transmissions done over the WEBRTC and all other data attached to it including the local IP address.
