Technically, no. That's a side effect of what DNSSEC does provide.

This will matter only if the folks not using Comcast realize they've been victimized by an attack that Comcast protected against. I figure the vast majority of folks haven't the slightest idea how they've been victimized. It might be useful for Comcast to widely publicize any attacks that DNSSEC actively prevents -- both to show how well Comcast's infrastructure is protecting customers as well as encourage other ISPs to take the same steps.

I agree. Very good job. I just hope the number of arrows Comcast suffers for being leaders doesn't kill the effort...
