Desktop? Can use the Networks GUI in the tray.

Ubuntu uses NetworkManager in 2025.

Refresh IP using NetworkManager:

  • nmcli connection show
    • Copy UUID.
  • nmcli connection down <UUID>
  • nmcli connection up <UUID>

Refresh IP using ip:

  • ip link
  • ip link set dev <DEVICE> down
  • ip link set dev <DEVICE> up

Info

  • ip a
  • nmcli

Find devices on LAN

  • ip neighbor
  • arp -a

Using ip is the standard cross-distro way, but nmcli might be a smoother experience on Ubuntu current year.
