VPN Use in Social Media -- Against Hacking

Hi, I hope someone can help me. I just recently saw a post on FB about a guy who had an argument (on the comsec) with an IT. The IT replied with his IP address as if a threat. My question is will someone still know my IP address when I’m using VPN if I have used the FB account outside VPN before?

I’m not sure how this IP address works or all these fancy computer stuffs, so if someone can also give me an idea about how one can possibly know my IP address or physical location. Thanks!

Seeing your IP address is like seeing the license plate on your car. Doesn’t give them the ability to know where you live. Only narrows it down to a very broad area.

Its very easy to get someone’s IP address but there’s not much you can do with that info.

All it does is say you’re in a very broad area.

As for attacks on that IP, that’s why we have firewalls.

And if someone decides to DDOS you, usually restarting your modem is enough to get a new IP from your ISP.

could they not exploit vulnerabilities in the persons router? I’d bet most people run old and outdated firmware on their routers with tons of vulnerabilities

Can a regular person get this info from an IP address or just LE?

Again, this is where firewalls are important.
Most people have every port closed making it very hard to actual get to anything useful for an attack. Are there ways through? Sure.

But are you worth someone’s time to figure out your hardware and formulate an attack against you personally?
Probably not when there are plenty of easier targets out there.

I would be more worried about hackers running automated scripts that just test their exploits on any router IP rather than being specifically targeted

doubt they give out info on a customer without an actual legal case, court order or police warrant or something, at least in EU, and definitely not to a random person willing to pay for it

Set up a web server and look at how much of that is already happening ufw and your routers firewall is enough to stop that.
They aren’t testing for vulnerabilities like that, they’re looking for exposed ports to get a foothold.
