IP Addresses can be classified into five classes A, B, C, D and E. Each class consists of a contiguous subset of the overall IPv4 address range. Class. Supports 16 million hosts on each of 127 networks. Supports 65,000 hosts on each of 16,000 networks. Supports 254 hosts on each of 2 million networks.
Note Class A. This was before CIDR. So, the Class A, B and C private address netblocks needed to come out of the correct IP ranges. I know that 172.16.0.0/12 was picked because it offered the most continuous block of Class B (/16) addresses in the IP space that was in a reserved block. know the concept of public IP, private IP ranges and its purpose. But a guy asked me couple of days back why particular range is choosen as private over other. I think its a Randon pick as they wanted to give private range for users(companies) from each class of network.
