Hereby my take on a scripted version of creating a networkpool in VCF! Please look at the code before using because there are some assumptions in there that may mess up your ip subnets. This is made for a customer based on their needs and design so test before using at your customer! This one will make a VSAN and vMotion pool, so there is room for improvement getting NFS and iSCSI in if there is a need for it!

#This script will take some input and uses it to generate the JSON file to create a network pool in SDDC Manager
#It will also create the pool for you.
