I was with you right with you (assign /48 to every customer, no
exceptions) up until you came up with the big-isp exception (assign /56
to private residences).<br>
<br>
Why would Comcast (using your example) customers get "only" a /56?<br>
<br>
Is there something wrong with the math (are big-isp's going to run out
of /48's)?<br>
<br>
If it is ok for Comcast customers to get /56's, why isn't it ok for all
other private residences to get /56's (what are the /56 customers
giving up)?<br>
<br>
As usual, I am horribly confused.<br>

It is very typical. /48 to every customer, no exceptions. If a customer
wants less, assign them a /48 anyway and only tell them the first part
of the prefix. When they get wiser, tell them the /48 that you
"reserved" for them.
The non-typical case is an ISP with very large numbers of residential
customers (something like Comcast for instance) where it makes sense
to assign /56 to private residences and /48 to everyone else.
