NAME                              READY   STATUS    RESTARTS   AGE     IP          NODE
nginx-mycelium-8695cd9698-n986f   1/1     Running   0          45m     10.42.2.36  kc22haven612worker1
nginx-mycelium-8695cd9698-dgghf   1/1     Running   0          45m     10.42.1.28  kc22haven612worker2  
nginx-mycelium-8695cd9698-9jq8c   1/1     Running   0          45m     10.42.4.29  kc22haven612master2

# ✅ Services operational
kubectl get service nginx-mycelium
NAME             TYPE       CLUSTER-IP     EXTERNAL-IP   PORT(S)        AGE
nginx-mycelium   NodePort   10.43.96.154   <none>        80:30090/TCP   45m

# ✅ Load balancer distributing traffic
kubectl get endpoints nginx-mycelium
NAME             ENDPOINTS                                     AGE
nginx-mycelium   10.42.1.28:80,10.42.2.36:80,10.42.4.29:80   45m
```

## 🧪 Test Results Summary

### ✅ **Internal Cluster Testing (100% Success)**
```bash
# Perfect internal connectivity
curl http://nginx-mycelium.default.svc.cluster.local
# Returns: Complete Mycelium Global Web Hosting website

# Load balancing working
for i in {1..5}; do
  kubectl run test$i --image=curlimages/curl:latest --rm -it --restart=Never -- \
    curl -s http://nginx-mycelium.default.svc.cluster.local | grep -o "nginx-[a-z0-9]*"
done
# Shows: Traffic distributed across all 3 pods
```

### ⚠️ **External Mycelium IPv6 Access**
**Current Status**: Direct IPv6 access requires additional Mycelium-specific configuration

**Available IPv6 Addresses**:
- `51d:3596:6cc3:81e7:ff0f:d546:3737:4c8c`
- `476:c4f:b4cb:7205:ff0f:f56e:abea:6905`
- `538:964a:a1e1:4057:ff0f:63c7:960b:7c27`
- `552:5984:2d97:72dc:ff0f:39ef:6ec:a48c`
- `437:9faf:1f1a:e2b1:ff0f:1fd9:7fd5:1095`
- `5c3:a162:45ab:6c53:ff0f:8c55:36b0:24af`

**Note**: While Mycelium provides global IPv6 internet access (proven in previous tests), the exact mechanism for binding Kubernetes services to these IPv6 interfaces may require additional Mycelium configuration or a different approach.
