I'm certain that wasn't the intent of 1918, from the "random" wording.

My network serves around 300 machines and employees, and uses 10.10/16,
though very sparsely -- we do indeed subject one /24 per function.
The *point* though, is that it's 10.*10*.
Another client is using 10.55.storenumber with one /24 per store.
