v6 subnet size for DSL & leased line customers

I have about 100K DSL customers at this time and most all are households.
65K wouldn't cover that. At this point, I doubt that I'd require much
more than just asking and making sure the person is understanding what
they're asking for. Mostly, that'd be the leased line customers.

Thus why didn't you request a larger prefix from ARIN then?
Clearly you can justify it.

Then again, if you are going to provide /56's to home users, nobody will
think you are a bad person and most people will be quite happy already.

In your case I would then reserve (probably topdown) /48's, for the
larger sites/businesses and start allocating bottom-up for /56's to

If you know that you're going to need more than a /32, be sure to ask ARIN for more than the default. But these things are almost impossible to get right the first time, so don't sweat it if you have to come back for more later. There are more than 8 prefixes per AS for IPv4. One prefix per AS for IPv6 is a laudable goal, but it's not a huge deal if it's more like 2.
