You have a few VNets, somebody keeps a spreadsheet with the CIDRs, and before creating a new network you check that the range is not already used. It works. Then the cloud estate grows. You have tens or hundreds of subscriptions, multiple regions, separate production and non-production environments, connectivity hubs, private endpoints, on-premises networks and different teams deploying infrastructure independently. At that point, the problem is no longer which CIDR should I use?
