[one-users] Network Address Pool allocating out of range addresses ?

[Gary Mazz]

Hi Ted,

Thanks for the tip ;)  The idea was to provision out of a pool and not 
require to administer ip addresses for each vm. Since the pool of VMs is 
small, it won't be a big issue.

I was looking at the code that generated the mask. It makes sense now 
that I see it. :)  For future reference, the IP address should be bounds 
checked across the constraints. In our configuration, we wanted the 
servers to be in the lower addresses in the mask and the upper addresses 
for the workload nodes.

cheers,
gary
