I'm still concerned that dialup and other such "end user" accounts will
be viewed as workstations to which single addresses will be assigned. I
know IPv6 is specified to require handing out blocks. I just wonder
whether that's how it'll happen.
>From ARIN's policy: "Addresses for dial-up lines should be assigned from
the SLA block. It is expected that longer prefixes should be used for
non-permanent, single-user connections." How will providers interpret
this? ARIN's policy says "The minimum assignment to end-user
organizations is a /48." But how does one define "end-user customer?" If
cable modem and DSL users (perhaps even dialups) do get this much space,
I think we'll all be very happy to be able to do without NAT. Until IPv6
service is offered for dialup and cable/DSL, we can just guess.
