Whereabouts

Whereabouts is a Kubernetes Container Network Interface (CNI) IP Address Management (IPAM) plugin designed to dynamically allocate and manage IP addresses for pods across multiple networks. It is commonly used in advanced Kubernetes networking scenarios, especially with Multus CNI, to ensure unique and conflict-free IP assignment.

The solution enables cluster-wide IP tracking using Kubernetes Custom Resource Definitions (CRDs), making it suitable for multi-node, multi-network environments. Whereabouts supports both IPv4 and IPv6 and is widely adopted in telecom, cloud-native, and NFV (Network Functions Virtualization) use cases.

Features of Whereabouts:

• CNI-based IP Address Management for Kubernetes pods.
• Dynamic and distributed IP allocation without conflicts.
• Seamless integration with Multus for secondary network interfaces.
• Uses Kubernetes CRDs to track and manage IP assignments.
• Supports IPv4 and IPv6 address ranges.
• Scalable and suitable for multi-node and multi-network clusters.

To check if Whereabouts is installed and accessible, use the following steps:

Check Whereabouts version:
$ /opt/cni/bin/whereabouts --version

Verify CNI binary location:
$ ls /opt/cni/bin | grep whereabouts
