I know there's a way with resource monitor, but this might make it easier, there's a way with /r/PsionSquared's lag tester as said here: "This doesn't show IPs (granted it'd take a line of code to do so), so it's still the same risk with or without."

What line of code would it be? I know nothing about coding or how to insert it and I thought this might be useful for people that play with bad apples
