How do I compute subnet ranges from a VPC (AWS) or Virtual Network (Azure) IP ranges?
Example:
If a virtual network or VPC has a IP range of 10.0.0.0/16, and if you would like to provision 256 IPs per subnet,
you have a potential to create 256 subnets.
i.e. Subnet1 10.0.0.1/24
Subnet2 10.0.0.2/24
Subnet3 10.0.0.3/24
Subnet4 10.0.0.4/24 and so on.....
This is as explained in the other post of ip range computation logic.
As the VPC range is 2^16 there can be 65536 IPs, which when split into groups of 256,
there can be 65536/256 = 256 groups i.e. 256 subnets.
Hope this helps!!
