Decent Overview, Bit out of Date

If you've ever wondered why when you've typed 'ifconfig' recently you don't get all of your IP addresses for an interface up amongst other things that is because it has been largely unmaintained and deprecated by 'ip'. To do that you would do 'ip addr show'.

'ip' is a bit of a Swiss army knife of a network command and an up to date overview of that would have been better.
