I am trying to add the ports used by carp(4) and pfsync(4) to this

Wikipedia article:

http://en.wikipedia.org/wiki/Well-known_ports

(The list includes "unofficial" ports.)
On http://www.openbsd.org/cgi-bin/man.cgi?query=pfsync

it says: "The protocol is IP protocol 240". I'm not sure if I

understand correctly. Does that mean that the port is 240? Does pfsync

use the TCP or UDP port (or both)?
I understand from http://www.openbsd.org/lyrics.html#35

that carp uses "IP protocol 112". Does that mean CARP's port is 112?

Does CARP use a TCP or UDP port, or both?
Many thanks in advance,
