While we are on this topic, is there a limit on the number of nodes per IP address? I have two nodes running on one IP (different ports), tried adding a third one, but it can't seem to be able to register:

There is a limit of two relays per IP. From the directory specificationhttps://gitweb.torproject.org/torspec.git/blob/HEAD:/dir-spec.txt (line 1773): "Authorities SHOULD 'disable' any relays in excess of 2 on any single IP." This limit was implemented in 2007 as a countermeasure to Sybil attackshttps://gitweb.torproject.org/torspec.git/blob/HEAD:/proposals/109-no-sharing-ips.txt .
