Question

Renew IP Address from Command Line on Unraid?

Answer

Run the following command to renew your DHCP lease on Unraid:

ifconfig br0 down && ifconfig br0 up

Why this works

Unraid uses a bridge interface (br0) by default for networking. Bringing the interface down and back up forces the system to release the current DHCP lease and request a new one from your DHCP server.

Important notes

  • If you're connected via SSH, this will temporarily disconnect your session
  • The command must be run as root (which is the default on Unraid)
  • Standard Linux commands like dhclient may not work reliably on Unraid due to its bridge-based network configuration
