Hi Michael,

Does that mean you actually used *less* BGP slots after getting your
ARIN addresses? So in your case, current ARIN policy was actually
counterproductive to its goal, causing you to announce *more* routes,

Hi David,

Interesting. How could we mitigate this risk in a potential policy?
You suggested requiring them to multihome for a year with PA space
first. What about something more direct like requiring some fair
minimum annual payment for their Internet services to weed out the
serious folks from the DSL posers? Let's brainstorm. Are there more
ways to mitigate this problem?
