adopted /24 as the cutoff point. If you make the cutoff point smaller, what is the new point... /26? /32?
Anything longer than /24 is unlikely to propogate far on the internet. You can all check your filters to see. I just checked mine, and neither Level3 nor Time Warner has tried to send me anything longer than /24 in recent history. If they did, it'd show up as hits on a distribute-list deny rule.
I realize that - I was posing a rhetorical question to the previous poster :)
This is actually in the ARIN "rules". Multihoming is justification (regardless of utilization) for one of the multihomed network's providers to assign them a /24.
Been down that road a few times too, both as a provider and a customer. jms
