This is a very simple pinger that Already has more than 3k links but you can use your own and throw them in. (You will see the needed format in the .txt file).

This can run multithreaded and if you have a very fast internet connection and good computer you can run it at a high amount of threads and it will ping your link super fast. Else you will see a high amount of errors.

But if you have slower internet connection leave it to 1 thread.

I still strongly suggest leaving it to 1 thread if you want the program to be 100% effective.
