It's obviously a troll trying to stir paranoia amongst innocent viewers.
If you have dynamic IP address, you can just go unplug your modem and your ip should change.
(if it doesn't change, you have static ip)
If you have static IP, then it's going to be more of a hassle and you might have to call your isp to get a tech guy to come in and replace modem
or you can buy your own modem and call them to set it up.
