The `tracert` command randomly takes about 50-90 seconds to finish, depending on *ISP,IIG and server jumping*. I've made a script which measure the time which took to run this command and use that number to calculate a *pseudo-random number*.
After initial testing, the script seems to be working fine and generates one pseudorandom number on a specific range of integers.
