My ISP gives me an IP in /126 subnet for my public interface, and routes my /64 through that (and if I wanted, I could get a /56 instead – not that I have any need for it).

In reply to nandhp.

sure I like having 100’s of addresses like anyone else (they still haven’t really fixed https in the client! it’s 2011!!!!) but for a router? All they need to do is barf out some OSPF/BGP table, and pass the flow……

According to RFC2373, "A single interface may also be assigned multiple IPv6 addresses of any type (unicast, anycast, and multicast) or scope." So even on a point-to-point link, you might have several addresses for each host. Of course, you might ask why you would want to do such a thing, but lots of people use virtual hosts on their web server; presumably some people might like to apply it to other protocols, like FTP or IRC.
