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
