Rick et al, I work at an ISP, and I know staff at several other ISPs, we are all trying to do this right. If a /56 makes sense and is supported by the IPv6 technology and we won't have issues supplying these to customers (technically speaking), then we will most likely do this or something similar. The issue is more of a nuanced issue. There seems to be a variance between "It's OK to just give out a /64" to "You better be thinking about giving out a /48". I can live in those boundaries and am most likely fine with either. I'm leaning toward a /56 for regular subscribers and a /48 only for business or large scale customers, and undecided on dial-up. How does this sound? This wasn't suppose to digress to this level of vitriol. - Brian

asingle /64. The number of addresses is not the point. The idea of getting rid of the horribleness that is CIDR is the point.You underestimate the power of the marketing department and the bean counters. I assure you, residential ISPs are looking for schemes to give out as little address space as possible.The current revision of IPv6 introduces a way to nail down theboundarybetween network and host. This is fantastic, from an implementation point of view. It simplifies the design of silicon for forwarding engines, etc.And it's 150% Wrong Thinking(tm). IPv6 is classless - PERIOD. The instant some idiot wires /64 into silicon, we're right back to not being able to use x.x.x.0 and x.x.x.255. Addresses are 128-bits; you cannot make any assumptions about what people may or may not be doing with those bits. If I don't use SLAAC, then I'm not bound by it's lame rules.You don't do that. Or at least, you shouldn't do that. :-) We
have
afairly reliable DNS system these days...And where did DNS get the name/number assignments? In my case, it's either been typed in by ME or automatically updated by DHCP. --Ricky
