Need help guy know my connection, service provider, and County I live in.

If he has your IP, then he can potentially trace you. It truly depends on how much this person knows, how much free time they have, and if you pissed them off enough.

I wouldn’t worry too much about it though. Monitor your home network, make sure your firewall/router firmware is up to date, and that you don’t have the default passwords set on it.
