Bro, if you're not trying to do anything illegal, why bother? Most "how to know someone's ip" methods are either useless or risky.
But yeah, your IP is visible to websites you visit, and some apps (like torrent clients) can leak it. If you're worried, check your IP with sites like whatismyip.com and see if it changes with a VPN.
As for finding others' IPs... unless you're a network admin, forget about it.
