Temporary IP Address Assignment

For temporary network configurations, you can use standard commands such as ip, ifconfig and route, which are also found on most other GNU/Linux operating systems. These commands allow you to configure settings which take effect immediately, however they are not persistent and will be lost after a reboot.
To temporarily configure an IP address, you can use the ifconfig command in the following manner. Just modify the IP address and subnet mask to match your network requirements.

sudo ifconfig eth0 10.0.0.100 netmask 255.255.255.0

To configure a default gateway, you can use the route command in the following manner. Modify the default gateway address to match your network requirements.

sudo route add default gw 10.0.0.1 eth0
