Hemant,
Fair enough. I suppose that there are enough /55's or /56's that every
household can have one; however, it does make "right sizing" the initial
allocation to the ISP very important. We would not want to be allocating
non-contiguous /28's on a regular basis :-)

Jeffrey,
The answer to your question is a yes. Alternatively, the ISP may just dole out
a delegated prefix shorter than a /64 and the CPE Rtr has to live with it but
the ISP may use something like a /55 that gives sufficient number of links in
the home LAN. I will reply to any more discussion on this thread once I reach
Hiroshima.

OK. Then the CPE router has a unique /64 for all of its broadcast domains? Does
that mean that the customer needs to tell the ISP how many /64 prefixes they
need?
