# Configure Device Network

You can set a device's IP addressing, gateway, DNS, and hostname from the cloud in the "Network" section of the Configuration tab, instead of editing config files on the device.

{% hint style="info" %}
Network configuration requires a device running firmware that reports network telemetry. On older firmware the "Network" section still appears, but detected interfaces and link status are not shown.
{% endhint %}

By default a device manages its own network (DHCP defaults or USB provisioning) and the cloud leaves it alone. To take over, open the "Network" section and click "Manage network from cloud". To hand control back, click "Stop managing from cloud".

## Configure a Port

Click "Add Port", or one of the detected-interface shortcuts next to it, to add a port. For each port:

* "Port": choose a detected interface or enter an interface name or MAC address. Ports are keyed by MAC address so configurations survive interface renames.
* Mode: "Static IP", "DHCP", or "Disabled".
* For "Static IP", set "Address (ip/prefix)" (ex: 192.168.1.50/24), "Gateway (one port only)", and "DNS servers".

A green dot next to an interface means a cable is connected, gray means no link.

Ports you do not configure stay on DHCP. Selecting "Static IP" replaces DHCP on that port, and "Disabled" takes the port down. Saving with no ports resets the device to DHCP on all ports.

Use "Hostname" to set the device hostname and "Fallback DNS servers (all ports)" to set DNS servers used across every port.

When you save, the device applies the configuration and automatically rolls back if the Roboflow API becomes unreachable afterward, so a bad change cannot strand the device.

## Extended Network Diagnostics

Enable the "Extended network diagnostics" toggle to have the device report deeper diagnostics in its healthcheck, including switch LLDP neighbors, DHCP leases, ARP table, and listening ports. Leave it off unless you are troubleshooting a network issue.
