Just to make you aware: Tying the size of networks to a "class" for knowing its size has been abandoned for decades. Forget the term "class x network". :-)
Ah, thank you. So the information at the bottom of the page I was
looking at is somewhere between obsolete and misleading, and I did not
know enough to pick out the "good" parts.
Calculators, such as the one Jack linked to, are much easier and more useful.
Interestingly, I have not found a calculator that accepts two IP
addresses (or ranges, as Jim started with) and returns the tightest
CIDR or subnet mask that covers both of them. Would be a fun little
programming exercise.
