He didn't really give much of a reason for the /127s yet. I think it's coming up in a later session. I think it basically boiled down to whether or not the customer would actually use anything bigger. I'll write back when we get into that discussion.
It's the IPv6 equiv of an IPv4 /30 link network. Then a /64 or whatever can be aimed to that link address. This is exactly what Bellsouth does for business DSL: the link has a dynamic address and your netblock is then routed to it. (this is confusing and unworkable for a lot of cheap hardware.)
Just use a /64 for the customer link. That allows them to have a CGA if they need one. Mark -- Mark Andrews, ISC 1 Seymour St., Dundas Valley, NSW 2117, Australia PHONE: +61 2 9871 4742 INTERNET: marka@isc.org
