I am writing a program in C# which uses browser. I need to find out what the computer's IP address is, so I can display it to the user. The program must run on browser.

    by "the computer" do you mean the computer that's hosting the web server or the computer that's using the browser? – D Stanley May 10 '22 at 16:07

    If this is running with an embedded browser on the end user's computer, and not a web server, also know that the IP address isn't a simple scalar value, like the amount of RAM. A computer might have multiple interfaces, each with it's own address. A single interface might additionally have multiple addresses. Further, these addresses might then be NAT'd to yet different addresses for public internet connection, and a gateway can even use different NAT values based on what you are connecting to. Finally, yes, all of these situations are less common... but _not as much so as you might think_. – Joel Coehoorn May 10 '22 at 16:11

  • That's called Geolocation, and the thing is it's based on recorded data that is very often stale and inaccurate. Geolocation can and will frequently be wrong. – Joel Coehoorn May 11 '22 at 21:37
