Kinda surprised no one mentioned this—but email headers can sometimes show IPs. If you're emailing someone, their IP *might* be in the metadata. But this depends on the email service, and it's not foolproof.
Still, trying to figure out how to know someone's ip this way is borderline creepy unless you have a legit reason (like reporting spam).
As for your own IP, yeah, it's exposed every time you go online. But unless you're targeted, no one cares.
