Speaking as a national network with millions of dollars invested (AAI), I tried for three months to get a Class B assigned. The total number of hosts didn't justify it, even though it was nationwide with many geographic sites that we wanted to subnet, and even though we are doing research in ATM SVC signalling, ATM multicast, NHRP, etc. So we got a CIDR block of Class C's, and as expected, many of our systems are turning out not to handle the required subnet masks without hacks. While this has all been a pain I wished to avoid, we do really need to get this CIDR stuff to work everywhere, and we really are running out of address space. So while I agree that address space struggles with the InterNIC aren't pleasant (or quick), I think they are doing what needs to be done to conserve a scarce, dwindling resource. - Phil
