Is this a BUG REPORT or FEATURE REQUEST?:

Uncomment only one, leave it on its own line:

/kind bug

/kind feature

What happened:
manually docker restart sandbox container, then sandbox container doesn't have IP address, but using "kubectl get pod" find that the pod have IP address 100.100.0.3

[root@node-29:~]$ kubectl get pod --all-namespaces -o wide
NAMESPACE NAME READY STATUS RESTARTS AGE IP NODE
k8s-test pod-nginx-pod-0-1-7ccqx 1/1 Running 9 1d 100.100.0.3 10.200.138.226

[root@node-32:~]$ nsenter --net=/proc/50906/ns/net ip addr

What you expected to happen:

manually docker restart sandbox container, sanbox container should have IP address and pod have IP address

How to reproduce it (as minimally and precisely as possible):

manually docker restart sandbox container，then using "nsenter --net=/proc/<sanndbox_Pid>/ns/net ip addr" check sandbox IP address, using "kubectl get pod" check pod IP address
