Wow, that reference guide is written to confuse people.
Nobody I know in the industry would refer to 10/8 as anything other than
an "8-bit subnet", or 172.16/12 as a "12-bit subnet", or 192.168/16 as a
"16-bit subnet"....
In the real world of networking, if you asked for a "24-bit block", you would
be given a /24, that is, a subnet consisting of 256 addresses.
