I am trying to make my board reachable online. So my idea was to change the the content of ’ > /etc/network/interfaces to the following: ```auto auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp ``` then restart the control service with `sudo systemctl restart networking` However when I run `hostname -I` I still get `192.168.2.99` How can I fix this issue? ---

By default eth0 is setup for DHCP if the board is connected to a DHCP server. You should not need to do anything. A static IP address is setup on eth0:0 which effectively an alias to eth0. You can ignore this if you want to use DHCP. If your board does not get an IP from the DHCP server (using default image) you should check the DHCP server, and the connection your board has to the network. Cathal ---
