Port 2848

I don't know if this is the proper forum for this question so if it's not
I'm sorry.

Appended is an excerpt of a log off of one of our firewalls. I think that
this guy is using AIM but I can't determine. The only thing I could come up
with for port 2847 is the AIMPP-Port Req (from all the port lists) and
nothing for 2848. 192.168.100.2 tries to connect to 206.204.212.226 on port
2847 then 2
minutes later to 206.204.52.98 on port 2848 then again to 206.204.212.226 13
minutes later and the pattern repeats. Do you think this has anything to do
with AIM or could it be some other software application that uses these
ports and the port listing for 2847 is not entirely correct?
