Yes. Efficient address utilization is a Good Thing.
I realize that technically they are valid addresses, but does anyone
assign a node or server which is a member of a /22 with a x.x.x.0
and x.x.x.255?
Great for router interfaces, loops, etc where you don't care that
broken or archaic systems cannot reach them, and where the humans
interacting with them should have no issues.
Until you assign a .255/32 to a router loopback interface and then find
that you can't get to it because some silly router between you and it
thinks '.255? that's a broadcast address.'
Been there...had to change the loopback IP.
