Another way to get the IP address of your machine with the arp command.

by

This command will lookup the network adapter that you are using and return the gateway IP address.

jason@eyjafjallajkull:~$ arp -n | grep : | awk '{print $1}'
10.10.0.1

This looks for the : character that is in the MAC address like this.

jason@Yog-Sothoth:~$ arp -n
Address                  HWtype  HWaddress           Flags Mask            Iface
192.168.1.1              ether   c8:14:51:5f:a9:47   C                     enp0s25

And then it returns the first entry which is the IP address. Yet another cool trick to return a IP address for your network hardware.

This command returns all IP addresses with accompanying broadcast addresses.

jason@Yog-Sothoth:~$ ip a | grep "brd"
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    link/ether 00:13:46:3a:02:83 brd ff:ff:ff:ff:ff:ff
    link/ether d0:50:99:0d:ab:0f brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.2/24 brd 192.168.1.255 scope global dynamic enp0s25
    link/ether 52:54:00:5b:ba:d8 brd ff:ff:ff:ff:ff:ff
    inet 192.168.122.1/24 brd 192.168.122.255 scope global virbr0
    link/ether 52:54:00:5b:ba:d8 brd ff:ff:ff:ff:ff:ff

Or this one. This lists all interfaces that are connected with IP addresses. This does include the loopback interface, as it does have an IP.

jason@Yog-Sothoth:~$ ifconfig | grep 'inet '
        inet 192.168.1.2  netmask 255.255.255.0  broadcast 192.168.1.255
        inet 127.0.0.1  netmask 255.0.0.0
        inet 192.168.122.1  netmask 255.255.255.0  broadcast 192.168.122.255
