GCP Compute Subnetwork

A GCP Compute Subnetwork is a regional, isolated segment of a Virtual Private Cloud (VPC) network that defines an IPv4 and/or IPv6 CIDR range from which internal IP addresses are allocated to Compute Engine resources such as VM instances, internal load balancers and Google-managed services. Each subnetwork belongs to exactly one VPC network and controls routing, firewall application and Private Google Access for the resources it contains.
For further details see the official Google Cloud documentation: https://cloud.google.com/compute/docs/reference/rest/v1/subnetworks/get

gcp-compute-network​

Every subnetwork is a child resource of a single VPC network. Overmind links the gcp-compute-subnetwork to its parent gcp-compute-network so that you can trace which VPC a given subnet lives in and assess blast radius or shared-trust concerns.

ip​

The CIDR ranges defined on the subnetwork translate into individual IP addresses that can be assigned to workloads. Overmind exposes these as ip items, enabling you to drill down from the subnet to the precise addresses in use and detect overlapping or misconfigured ranges across cloud providers.
