If someone has my IP address, what can they actually do? Should I be worried? or How much trouble can

"if someone has my ip address what can they do? should i be worried?"

hey guys, so i was gaming last night and some dude got mad and said he had my ip. now i’m lowkey freaking out lol.

like, what can they *actually* do with it? i know they can’t like hack me instantly or whatever, but can they mess with my internet? ddos me? find my location??

i’ve heard mixed things—some say it’s nbd, others make it sound scary af. just wanna know if i should reset my router or chill.

pls help a paranoid noob out 😅

(also, if someone has my ip address what can they do *worst-case*? just so i know.)

thanks!
