If you are a mid-level ISP, you may have a choke point to your customer
but are vulnerable from your upstream provider. A better designed worm
could impact even major backbones.


If you are an access provider, specially in the consumer space, you can do many things
to help the "Greater Internet" by keeping your own back yard in good shape.
In the transit business, you are expected to deliver the bits regardless of the content
so there the only viable option is to drop packets where the source or destination
addresses don�t make sense.
