Tony, TH> With this type of policy, the operations community is dictating which TH> applications can be run from specific ranges of IP addresses. Does an ISP have a *right* to specify what applications may be run by their customers? Well, certainly an ISP has a right to make specifications concerning consumption of the ISP's resources, and restrictions of applications might be seen as falling under this. That said, yes, this is about as dumb as an ISP's rules can get. Certainly as cynical and possibly as manipulative. The question is what the IETF can or should do about bad ISP customer policies, when those policies do not cause operations problems for the rest of the Internet? d/ ps. When AOL, MSN and Yahoo announced that they were going to lead an initiative for spam control, it *did* occur to me that the policies that might be tolerable for their mass-market customers would be entirely inappropriate and damaging to the rest of the Internet's user base. -- Dave Crocker <mailto:dcrocker@brandenburg.com> Brandenburg InternetWorking <http://www.brandenburg.com> Sunnyvale, CA USA <tel:+1.408.246.8253>, <fax:+1.866.358.5301>
