[ogf20pc] Network question

[Fotis Karayannis]

Hi Stephen,
  I can link you with my networking guys that did both the EGEE-3 
conference and the GGF16 in Athens. For those we got 4 class C addresses 
(a bit more than a thousand IPs). Indeed it takes some negotiation with 
the national registry, but it is a standard procedure.

Your hybrid solution is also ok (and maybe more secure) but indeed adds 
  to the complexity.
Let's take the rest off line,
All the best,
Fotis
