+-01-03
+Following some improvements in the kernel and the gradual move to driving network things via netlink; ifconfig has been largely replaced by the ip command.
+Running just ip yields the following:
+I understand this may look complicated to some people, but the jist of it is to understand that with ip, you interact with objects, and apply some kind of function to it. For example:
+    ip address show
+This is the main command that would be used in place of ifconfig. It will just display the IP addresses assigned to all interfaces. To be precise, it will show you the layer 3 details the interface: the IPv4 and IPv6 addresses, whether it is up, what are the different properties related to the addresses…
+Another command will give you details about the layer 2 properties of the interface: its MAC address (ethernet address), etc; even if it is shown by ip address:
+    ip link show
+Furthermore, you can set devices up or down (similar to ifconfig eth0 up or ifconfig eth0 down) simply by using:
+    ip link set DEVICE up or ip link set DEVICE down
