So here are the questions for actual IPv6 services providers to residential customers: 1) What prefix size is provided? 2) Is that prefix static or dynamic? 3) In case is dynamic, there is a chance for static? 4) Any extra cost for having it static, or having a bigger prefix (i.e., /48 instead of /56)? 5) If the customer has already a static IPv4 with a monthly charge, is still IPv6 static prefix being charged on top of that?
A related question that is not on the list above: 6) Can the customer delegate reverse DNS for the assigned IPv6 prefix? 6a) If the prefix is static, can they use an NS delegation? 6b) If the prefix is dynamic, can they consistently DNAME it to a customer-hosted zone that contains PTRs for 'some-subnet-size'? Of course, most residential customers probably don't care. But I mention it as both a DNS and IPv6 geek. It's something to consider. Colin
