+
+# Configure IPv6
+
+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.
+
+## Protocol configuration
+
+This sample listen configuration will allow the gRPC and HTTP servers to listen on IPv6, and configure the various memberlist components to enable IPv6.
+
+```yaml
+memberlist:
+  bind_addr:
+    - '::'
+  bind_port: 7946
+
+compactor:
+  ring:
+    kvstore:
+      store: memberlist
+    enable_inet6: true
+
+metrics_generator:
+  ring:
+    enable_inet6: true
+
+ingester:
+  lifecycler:
+    address: '::'
+    enable_inet6: true
+
+server:
+  grpc_listen_address: '[::0]'
+  grpc_listen_port: 9095
+  http_listen_address: '[::0]'
+  http_listen_port: 3200
+```
+
+## Kubernetes service configuration
+
+Each service fronting the workloads will need to be configured with with `spec.ipFamilies` and `spec.ipFamilyPolicy` set. See this `compactor` example.
+
+```yaml
+apiVersion: v1
+kind: Service
+metadata:
+  labels:
+    name: compactor
+  name: compactor
+  namespace: trace
+spec:
+  clusterIP: fccb::31a7
+  clusterIPs:
+    - fccb::31a7
+  internalTrafficPolicy: Cluster
+  ipFamilies:
+    - IPv6
+  ipFamilyPolicy: SingleStack
+  ports:
+    - name: compactor-http-metrics
+      port: 3200
+      protocol: TCP
+      targetPort: 3200
+  selector:
+    app: compactor
+    name: compactor
+  sessionAffinity: None
+  type: ClusterIP
+```
+
+You can check the listening service from within a pod.
+
+```sh
+❯ k exec -it compactor-55c778b8d9-2kch2 -- sh
+/ # apk add iproute2
+OK: 12 MiB in 27 packages
