Re: Hulu thinks all my IP addresses are "business class", how to reach them?

[Blake Hudson <blake () ispn net>]

This is absolutely an issue with Xbox Live/Sony PSN or RBLs used by mail 
servers for reputation purposes. For better or worse these systems 
equate one IPv4 address == one user (and possibly one IPv6 /64 == one 
user). My opinion is that this may be a reasonable or "good enough" 
assumption as long as you put a time limit on the assumption (so dynamic 
addresses can be reassigned) and have a rough idea of what a user means 
(a household, subscriber circuit, or similar). But it obviously goes out 
the window if you have 10 or 20 unrelated subscribers (possibly in 
different towns) sharing a single IP address in a 1:many NAT. This may 
be one of the not-so-obvious support costs that comes up when one 
decides to run a CGN.
