in reply to How many addresses between two IPs?

Good stuff, but as an experienced professional network engineer, I'd keep more than 22 addresses reserved. Lots of things need/work better with static addresses. Like shared printers, "special people" who need special holes in the firewall, manageable network equipment (how are you going to deploy 1000 ports without having several chassis?) etc.

We like to use /22's here, and typically reserve one entire class C from each range for static addresses. That is a bit of overkill, but I'd guess we have a minimum of 50 static/reserved addresses used in each of our /22 networks.

YMMV of course.
