-====== Ubuntu - Network - Get Network Details ======
-To get the details of your own systems, begin by finding your network interfaces. You can find the interfaces on your machines and the addresses associated with them by typing:
-<code bash>
-ip -4 addr show scope global
-</code>
-returns:
-<code bash>
-: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
-    inet 198.51.100.45/18 brd 45.55.191.255 scope global eth0
-       valid_lft forever preferred_lft forever
-: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
-    inet 192.168.1.5/16 brd 10.132.255.255 scope global eth1
-       valid_lft forever preferred_lft forever
-</code>
-The highlighted output above shows two interfaces (eth0 and eth1) and the addresses assigned to each.
-----
-To find out which of these interfaces is your public interface, type:
-<code bash>
-ip route show | grep default
-</code>
-returns:
-<code bash>
-default via 111.111.111.111 dev eth0
-</code>
-The interface shown (eth0 in this example) will be the interface connected to your default gateway.  This is almost certainly your public interface.
