Tempo can be configured to communicate between the components using Internet Protocol Version 6, or IPv6.
Note: In order to support this support this configuration, the underlying infrastructure must support this address family. This configuration may be used in a single-stack IPv6 environment, or in a dual-stack environment where both IPv6 and IPv4 are present. In a dual-stack scenario, only one address family may be configured at a time, and all components must be configured for that address family.
This sample listen configuration will allow the gRPC and HTTP servers to listen on IPv6, and configure the various memberlist components to enable IPv6.

Kubernetes service configuration
Each service fronting the workloads will need to be configured with with
spec.ipFamilyPolicy set. See this

You can check the listening service from within a pod.
