It's the IPv6 equiv of an IPv4 /30 link network.  Then a /64 or whatever  
can be aimed to that link address.  This is exactly what Bellsouth does  
for business DSL: the link has a dynamic address and your netblock is then  
routed to it. (this is confusing and unworkable for a lot of cheap  
hardware.)
