Down flag with interface name disables the network interface

To know the routing table information of the system

Output Example:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 ...
    inet 127.0.0.1/8 scope host lo
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 ...
    inet 192.168.1.10/24 brd 192.168.1.255 scope global eth0
