Sorry, I left out an important "What this report is" section.

It is the top 100 nameservers serving .com, .net and .org domains.

I'm not quite sure where to *get* that data, though.

I started analyzing the zone files to track down domains that claimed our
nameservers were authoratative for them, yet I had never heard of. Then I
got a whim to start counting them... I've actually had a lot of good
feedback on additions to the report and I plan to put it on the web with
weekly updates.

I've also played around with other statistics on the domains, like: is a
nameserver really responding for it? Is the domain just a MX entry? How
many www.domain.x are pointing at the same IP addresses?

(I'm also intrigued with the number of domains removed from week to week.)
