This makes absolutely no sense to me.  If you know something I don't,
please explain it to me. :)

According to what I've learned (mostly from Scott Mann's _Linux TCP-IP
Network Administration_), that's totally wrong.  Your netmasks doesn't
correspond with what size you're saying the subnets are (/24).  /24
*means* a netmask of 255.255.255.0.  255.255.252.0 specifies a /22.

The result, in this case, is that there is a range of addresses which
will be unreachable because according to the netmask they are on the
local network, whereas in reality they are on another subnet.
