Someone told me there is a way to get an IP address from a youtube post. Is this true?

Not sure exactly what they told you, but in my experience when someone has discovered a brilliant way to get a user’s IP address, it turns out what they’ve actually discovered is that you can – very easily! – get the IP of the server your computer/device is connected to. Which tells you absolutely nothing – other than the fact that you’re currently browsing YouTube, or Zodiackillersite, or whatever the case may be.

I’m sure you can get an individual user’s IP through some hackery or other, but even that isn’t very useful in terms of tracking down the person. If the idea is to ascertain whether said user is identical to another user (e.g. someone on this site), however, I suppose you might narrow that down to a fair degree – even though most regular, private Internet subscribers do not have static IPs (meaning that "dimwit666"’s IP may show up as A today and B tomorrow even though he’s not doing anything actively to make it so).

what norse said. i have nearly twenty years in IT. the only ip you’re getting by watching a youtube video is the ip address of the specific video serving server to which you’re connected. the upload process (where the uploader’s IP is involved) is an entirely separate process on an entirely separate set of machines. it’s possible to get some metadata from an image or video but i’m pretty sure youtube strips that information when a video is uploaded (they also convert uploaded videos to a format that uses an algorithm to minimize size while maximizing quality). metadata would be stuff like the camera used, date the image or video was taken, sometimes the geographical location where it was taken, etc.
