Ummm... You entered the wrong IP. I did a port scan and it is dead. Definitely not Tor.
No, it isn't the wrong IP, unless you gave us the wrong IP. The IP address you posted is in the list. As to why your port scan comes up empty-handed, it could be filtering incoming connections, or just be too bogged down to handle your connection attempt.
Right -- that is a list of some Tor exit nodes among which the offending IP is listed. That IP in the URL (194.63.142.59) was just part of the search result link from Google but that wasn't the important part.
