I won't disagree with your statement about CIDR, but 255.0.0.0 is the
natural mask
for the 10. network. Lot's of people lose sight of the fact that you can use
any
_correct_ mask within a network no problem. I once gave a customer an IP
conversion to 10.200.50.xxx since everyone in the world seems to use the
192.168
and 172.16 networks for privates, and the assigned range is perfectly valid
using a
class C mask, worked fine.
For networks not using CIDR or VLSM, just use the correct mask, and you can
avoid
lot's of connectivity issues provided that you're not using the same IP
block as someone
else, etc.
