Which limit is considered a hard limit for the number of primary IP ranges per subnet?

In Google Cloud, the configuration of subnets is critical for organizing and managing network resources effectively. A hard limit refers to a restriction that cannot be exceeded, and in this case, the number of primary IP ranges that can be assigned to a single subnet in Google Cloud is set at one. This means that each subnet can have only one primary IP range, which dictates the IP addressing within that subnet.

This limit is important because it simplifies the management of IP addresses within a virtual private cloud (VPC) and ensures clarity in routing and network traffic management. Having a single primary IP range helps streamline configurations and reduces the risk of overlapping IP addresses or conflicting routes within a subnet.

The focus on maintaining a singular primary IP range aligns with best practices for subnet design, promoting better organization and performance within the cloud network. For those managing Google Cloud networks, understanding this hard limit is essential for effective architecture planning and implementation.
