My thoughts on this is that unless ISPs start to announce what "one 
customer" is, this is pretty hard. It's a problem in IPv4, but even more 
so in IPv6.

Wouldn't it help a lot if there was a way to publish that "in this /42, 
there is one customer per /56, and in this other /42, there is one 
customer per /48"?

How can that be done via DNS (if that is still a favourable mechanism to 
distribute information like this)? Whois is not a good way...
