Use the** Kubernetes Bridge Settings **page to set the IP block or the network CIDR ranges for your Kubernetes clusters and services. These settings affect only Kubernetes OVA and appliance-type deployments that use the Infoblox image.

The settings on the** Kubernetes Bridge Settings **page are also available on the device’s UI; for more information, see *[Troubleshooting Servers](https://infoblox-docs.atlassian.net/wiki/spaces/BloxOneInfrastructure/pages/184681229)*. If you want to reconnect a Kubernetes-based NIOS-X server that has already been disconnected AND you also want to change the Kubernetes CIDR settings, you must first reset the NIOS-X server before making the CIDR changes and reconnecting the NIOS-X server.

To configure a Kubernetes Bridge, specify the following:

- **Cluster CIDR**: Select one of the following to define the IP block for your Kubernetes cluster:
  - **Use default**:** 10.42.0.0/16**: Select this to use the displayed CIDR for your Kubernetes clusters.
  - **Use custom**: Select this and then enter a valid CIDR for your Kubernetes cluster. Ensure that you have set the netmask to a network no larger than /24 and that you have enough IP addresses for the pods in the cluster.
- **Service CIDR**: A service enables network access to a set of pods in Kubernetes. Select one of the following:
  - **Use default**:** 10.43.0.0/16**: Select this to use the displayed CIDR for your Kubernetes services.
  - **Use custom**: Select this and then enter a valid CIDR for your Kubernetes service. Ensure that you have set the netmask to a network no larger than /24 and that you have enough IP addresses for the services.

> 📝 Infoblox strongly recommends configuring CIDR for the Kubernetes Bridge separately from other IP address changes, such as static IP addresses or DHCP ranges. Performing these operations simultaneously can create issues in your system. If both CIDR configuration and IP address changes are required, ensure that you complete the CIDR configuration before the IP address changes, or vice versa, one operation at a time.
