Always wondered if CU reveals account creation IP. Some of my socks with 0 edits were catched.
Well-known for ages. The answer is "yes", though the word you are looking for is "caught". Also, CU Wiki retains records on actual or suspected sockpuppets indefinitely, so if you're a sock, never re-use an IP. If someone else re-uses the IP and tickles a checkuser's interest, they are likely to be banned, regardless of guilt. I've now collected a list of at least 20 "sockpuppets" that I had nothing to do with. Wikipedia doesn't care, they want to be seen as fighting the enemies of the Wiki.
