Missing feature on this?

[Jerry Yang]

Hi Team, Great job.

I need to 'split' an Vnet Address space into N subnets and each with their own number of IP addresses.

For example:
vNet is '10.0.0.0/16' and I need 5 subnets with number of Ips as 256, 256, 256, 16, 2096.

How to code this into a python program? if missing feature, please add.
