Your team needs to create a virtual network that spans multiple GCP projects. You also need fine-grained control over the routing and IP address range for the virtual network. Which GCP networking product will allow you to achieve this?

*Explanation:* Shared VPC is the correct choice for your scenario. It allows an organization to connect resources from multiple projects to a common VPC while providing fine-grained control over routing and IP address ranges. VPC Network Peering connects VPCs but doesn't span multiple projects. Cloud Interconnect extends on-premise networks to Google's network. Cloud VPN connects on-premise networks to Google Cloud. Cloud NAT is used for allowing private RFC 1918 traffic to access the internet and does not address your specific requirement.
