On the wire, there would *be* a /64.
This deployment is just "virtually carve the /64 into smaller chunks so that
customers/server admins asking for addresses for the virtual servers know
which range to use".
This is not violating any of the established principles ("one /64 on
each LAN!"), it's just easing the housekeeping.
(Furthermore, what sort of software would run on a virtual web server(!) that
cares how big the LAN prefix is? In this context, you don't run routing
daemons - and normal userland software has no business caring about prefix
size. Yes, SeND comes to mind, but that doesn't work with statically
assigned addresses anyway)
did you enable IPv6 on something today...?
