[Nathan Whitehorn <nathanw@xxxxxxxxxxxx>]

IPv6 requires that every device have at least two addresses: a link-local 
address (fe80::) and a global address (e.g. 2001::). There is even an 
additional domain beyond that for organizational internal routing, and 
machines adhering to the anonymous IPv6 address spec will typically have 
two global addresses at a time during an address transition.

Aliasing is also fantastically useful for IPv4 when hosts move or you want 
an internal/external addressing scheme like IPv6 uses. Maybe only a few 
people will use it, but it's good to have.
