    - lo - Is the local loopback address. The loopback address is used to establish an IP connection to the same machine or computer being used by the end-user. The loopback construct gives a computer or device capable of networking the capability to validate or establish the IP stack on the machine.
  - If your host machine has Internet Connectivity, but LosBuntu does not have an IP Address associated with eth0, then issue the following command as root.
    - dhclient -v
