Acceptable prefix sizes for Windows Vista/7

[Frank Bulk]

I was testing a residential broadband router's implementation of IPv6 and
found that it wasn't using the first /64 in the delegated prefix, but the
whole /56.  And my Windows 7 machine wasn't getting an IP address.  Switched
the LAN interface of the router to stateful DHCPv6 and I could get an IP.

 

Does Windows possibly have a requirement that the advertised prefix only be
a /64 in order for SLAAC to work?
