Nitpick: it's a concatenation of 256 Class C nets, not a Class B
one. And there's no Class C network.
>From RFC 1918:
| 3. Private Address Space
|
| The Internet Assigned Numbers Authority (IANA) has reserved the
| following three blocks of the IP address space for private internets:
|
| 10.0.0.0 - 10.255.255.255 (10/8 prefix)
| 172.16.0.0 - 172.31.255.255 (172.16/12 prefix)
| 192.168.0.0 - 192.168.255.255 (192.168/16 prefix)
|
| We will refer to the first block as "24-bit block", the second as
| "20-bit block", and to the third as "16-bit" block. Note that (in
| pre-CIDR notation) the first block is nothing but a single class A
| network number, while the second block is a set of 16 contiguous
| class B network numbers, and third block is a set of 256 contiguous
| class C network numbers.
We all needed to know this, didn't we?
