What is the maximum number of secondary IP ranges that can be assigned per subnet?

The maximum number of secondary IP ranges that can be assigned to a subnet in Google Cloud is indeed 30. Secondary IP ranges allow you to create additional IP address spaces within a subnet which can be particularly useful for certain configurations, such as alias IPs, Kubernetes clusters, or Google Cloud's serverless products.

Having up to 30 secondary IP ranges enables enhanced flexibility when managing workloads that require multiple distinct IP addresses for different applications or services that operate on the same subnet. Each secondary IP range can be utilized for specific use cases like managing load balancers or providing IP address management for various services while ensuring they coexist without conflict.

In practical scenarios, this flexibility is essential for efficiently designing network architectures that can scale and accommodate diverse resource demands while maintaining streamlined network management. The ability to utilize multiple secondary IP ranges contributes significantly to the overall efficiency and organization of network resources in a cloud environment.
