Hi! I barely know anything about how the internet works so please bear with me.

I've seen scam ads that say "Your computer may be broadcasting your IP address to attackers! Click here to correct this!". I don't click them, but it's made me wonder if there is any element of truth to that.

What can someone do if they know your IP address? Is it a bad thing for someone to know your IP address?

As I said, I'm a complete newb so I hope those questions even make sense!
