+# Static IP for minikube containers KIC Drivers (docker/podman)
+
+design by @medyagh
+
+## Prototype [PR 9294](https://github.com/kubernetes/minikube/pull/9294):
+
+Each minikube cluster will get it is own network, instead of using docker’s owned default network which is unmodifiable by the user.
+
+on “minikube start”, minikube will try to create a docker network at a default subnet
+If a user happens to have an existing network in that exact subnet, minikube will try X times, by incrementing the sunbet by 10 each time.
+
+once the network is created, it will calculate container IP inside the network by this formula:
+
+```
+gateway IP = first ip of the subnet
+container IP = gateway IP + 1 + container index
+```
+
+container_index is calculated from this formula:
+
+default is 1 for single node (and for multinde is the order the machine created based on it is name, for example the index for minikube-m02 will be 2)
+
+
+
+### Alternative design :
+
+once network is found or created, minikube can look up list of all the container IPs in the network, and try to 
+
+
+### Considerations:
+
+if can’t create network, should fall back to docker’s default bridge IP
+The existing running clusters should not break by using newer version of minikube
+
+
+### Advantages:
+
+since we own the created network we can assign and calculate the IP.
+By avoiding using the default docker bridge we can isolate minikube network problems to not be affected by user’s other containers.
+User will have the same minikube IP across computer restart and hibernations, which will save user time on the next start. (each time IP changes there will be a tax of 22 seconds of setting up the cluster by kubeadm)
