# Network configuration

**Setting a static IP address.**
Do this from the console, because the SSH session is lost when the address changes (reconnect after change of the IP is possible, but there is a risc of cut off yourself).
Replace the example addresses with your own.

```
set ietf-interfaces:interfaces/interface[name='br0']/ietf-ip:ipv4/czechlight-network:dhcp-client/czechlight-network:enabled false
set ietf-interfaces:interfaces/interface[name='br0']/ietf-ip:ipv4/ietf-ip:address[ip='NEW_IP']/ietf-ip:prefix-length 24
