Hello all,
while trying to resolve some troubles in our internal subnet configuration, I 
was wondering how *exactly* the VenueServer assigns/manages addresses for the 
venues. What I know, from official documentation and from Thomas D. Uram 
messages inside this m/list, is that the management of the IP for the venues 
can be either static or dynamic, meaning that I can assign a fixed IP to each 
venue (one for video, one for audio, and it will have always the same) or let 
the venueserver assign the IPs inside a variable range, giving them to 
audio/video of a venue when the first user asks to enter it, while releasing 
them when the last person into the venue leaves it.
What I'm not able to understand is:

1) is the IP assigned to audio/video for each room a *real* IP (a multicast IP 
publicly visible over the internet i mean) or is there some kind of 
alias/routing sistem underlying somewhere?
2) In the first case, how can the venue server understand a particular IP is 
"free" or "used" by someone else (i.e. another venueserver or another service)?
3) In the second case, how is the routing done? How can the venueserver address 
the two applications Vic and Rat (with some kind of DNS i guess) to the right 
IP?
4) Again in the second case, how can the VenueServer assign/manage addresses in 
ranges like 224.xxx.xxx.xxx when the allowed IPs inside a LAN are restricted to 
a range that goes from 192.168.2.10 to 192.168.2.150?

I'm not sure if I could explain clearly what I'm looking for, but this matter, 
as far as now, is very critical to me, I'm ready to give any further 
clarification and open to every suggestion and information.
Thanx as always,
Faber B.
