"networking 101"?

- don't use IP addresses out of Class D or E space
- don't use netmasks that are not left-contiguous (no 0-bits mixed into
  1-bits)
- don't use /32 masks on anything that's not a loopback
- don't use IP addresses that would be the network or broadcast address
  in a given subnet

In essence, except for the non-contiguous netmask thing "don't do things
that are not permitted by the networking-101 text book".  And don't use
IPv4 either.
