Right, but since each border router off of the public Internet can't advertise anything smaller than /24 (would *your* router accept an advertisement for 3.0.0.0/27?), each seperate office needs at least a /24. Yeah, NAT can take care of the internal addressing, but you're still stuck with the fact that you "only" can have 256 seperate border routers. I was never arguing that GE needs and/or deserves the full 3.0.0.0, as I have little or no experience with their network needs. (I do note, however, that I can't find *any* of 3.0.0.0/8 in Mae-East via Digex right now). I believe it was Lee Ving who said "Let's have a war/We need the space".
