This tool is ridiculously simple. It shows you the public IP address of the device you are using.
There are a million of these IP address display tools on google when searching “what is my IP”, even google itself will tell you your IP address above the search results.
What I don’t understand is why these all have to be on a web page surrounded by crap, advertisements, or pretty much anything.
This tool gives you absolutely nothing except your IP address and is secured with HTTPS. I like to use it in scripts so I don’t have to parse a bunch of shit just to get the IP, or sending the link to a customer if I need to know their public IP.
