The list your host has is usually in /etc/services. The full list of
assigned protocol #s is maintained by IANA. But both of those are really
laundry lists.
The best bet is to build your own based on the protocols you know are being
used on your network and windowing that down to what you care about. You
can use tcpdump to scan for you (a cheat is to do something like this:
tcpdump -c5000 "ip" | awk '{print $2 " " $4}' | sort | uniq
IM is tough - while AOL IM uses 5190 by default, it can actually use a wide
range of ports to get through firewalls, including FTP and HTTP ports.

Subject: [Ntop] protocol list
Hello,
Does anyone out there have a good starter protocol.list file to distinguish
more than the basic http, ftp, etc. ? I'm looking to have ntop give stats
on things like netradio, Instant messenger, etc.
Thanks in Advance
John Hally
