What is My IP Address is a lite add-on that let you view your public IP address in toolbar popup UI.
Simply open the UI and select a desired server from the list. Two types of servers are available in the list, HTTP or STUN. STUN servers use WebRTC technology to find your IP address. HTTP servers use fetch API to obtain the IP address.
In general, all third-part servers should show a similar IP address. But, in some situations, they might show different IP addresses. All changes in the popup UI are auto-saved to the memory.
