Instructions

Command Line

Let's start by using the terminal to display your internal IP address. Open up terminal and execute:
$ ip a
1: lo:  mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: enp0s3:  mtu 1500 qdisc fq_codel state UP group default qlen 1000
    link/ether 08:00:27:2f:a4:ad brd ff:ff:ff:ff:ff:ff
    inet 10.1.1.4/8 brd 10.255.255.255 scope global dynamic enp0s3
       valid_lft 84760sec preferred_lft 84760sec
    inet6 fe80::db46:468e:e4cf:be5/64 scope link 
       valid_lft forever preferred_lft forever


Locate your interface eg. enp0s3 and search for the IP address. Reading the above ip command output our IP address is 10.1.1.4. Additional information included is MAC address 08:00:27:2f:a4:ad and network mask 10.255.255.255.
