That is not the new question -- i was trying to obtain the block equal to 8k class Cs a year ago -- unsuccessfully. How about treating Sprint's allocations as allocations for 10 providers in different geographical areas? --vadim Sean, Currently Sprint receives the largest sized CIDR block the InterNIC is permitted to allocate. If you have a requirement for an even larger block than please submit the justification and I will be glad to pass it onto the IANA for approval. Kim Hubbard InterNIC Registry

Unfortunately, the allocations we've been getting haven't been very big, and so we end up having to introduce things as long as 17 bits to the world, where we might have only had to announce /16s and /15s with a larger delegation from a registry.

Block Name Total Free Used Free Blocks Cs Cs 1 2 4 8 16 32 64 128 256 512 1024 -------------------------------------------------------------------------- East 2863 233 91% 1 1 1 1 1 West 2176 51 97% 1 1 1 1 South 2176 47 97% 1 1 1 1 1 North 1920 218 88% 1 1 1 1 1 NorthEast 1408 211 85% 1 1 1 1 1 SouthWest 768 173 77% 1 1 1 1 1 NYSERNet 512 129 74% 1 1 ICM-Atlantic 128 122 4% 1 1 1 1 1 -------------------------------------------------------------------------- TOTAL 11951 1184 90% 6 5 2 5 4 5 4 5

So, beacause we are clever and do a mix of provider-based and geography-based allocation (but it is a mix of both, with an emphasis on the provider part), we end up with blocks that are starving, but a single huge allocation that isn't full enough to have a new large allocation done by the registry.
