So you're saying that with 10.200.200.0/22, that 10.200.201.0,
10.200.202.0 and 10.200.203.0 are invalid host addresses? Setting up
DHCP scopes for this space must be painful.

Not to mention use of /32 addressing for loopbacks. I could almost
forgive not handling /31 given that RFC3021 was onlyu published in
12/2000.
