Several years ago I remember seeing a mathematical justification for it, and I remember thinking at the time it made a lot of sense, but now I can't find it.
Hi Jerry, If there's special ASIC-friendly math here, beyond what was later generalized with CIDR, it's not obvious. 10.0: 0000 1010 0000 0000 172.16: 1010 1100 0001 0000 172.31: 1010 1100 0001 1111 192.168: 1100 0000 1010 1000 AFAIK, it was simply one range each from classes A, B and C.
