i have to wonder - and this is an actual question, please answer if you have insight - how harmful can knowing someone's IP address be?
what harms can you actually do, especially if none of their ports are exposed? is a DDoS on someone's residential IP still an actual viable attack? and geo IP seems rather unreliable (sometimes it can get my city, but other times it pins me somewhere a decent distance away, and i've heard stories of it outright just saying tons of IPs are located at some random poor soul's home), is it actually more reliable on some people? or is it still a danger despite its unreliability?
i know i see some folks really wanting to obscure or hide their IP addresses from public view, and I do so as well at times, but, then. like. i see people with chops in computer security freely post their IP, and i know people who both hate cloudflare and host servers from their own home, and i have to wonder if there's any actual danger.
