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. ---------------------------------------------------------------------- Jon Lewis | I route Senior Network Engineer | therefore you are Atlantic Net | _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________
