Comcast.net has 31,923 addresses listed at the moment.
Do they have 30,000 zombies, or 30,000 customers that post to popular mailing
lists? Quite possibly at least partly the latter, as 24.22.118.199 ranks a 3.0
and isn't (as far as I know) a spam zombie, but a frequent poster to the
linux-kernel list. Meanwhile, of those 31,923, only 1,969 have a monthly
magnitude of 4.7 or more, the 4.8 cutoff is at 1,567, and the last 4.9 is at
1,012. And that 4.9 is (roughly) twice as much as I generate...
They have approximately 40,000 zombies (as mesured over all of their
ASNs, from 01-JAN to yesterday).
