It is defined that way, because this network is big enough to hold 253 hosts
and the 10.x.x.x/8 network is big enough to hold 65535 of those networks.

It is commonly used in cooperate networks for a site, and multiple sites are
referenced like this:

10.0.0.x <- main site, computing center
10.1.x.x <- remote networks
10.1.1.x <- site a in A
10.1.2.x <- site b in B
10.2.x.x <- RAS networks
10.2.1.x <- dialup accounts on ras server a
...

or something like that.

this is convinient, but beware network ten.
