Re: Top 100 Nameservers (Serving the most Domains)
Hi, nice report! It's not entirely clear what your data source is; I guess it's the zone files for the domains currently under InterNIC's administration, yes? To prevent anyone from taking this report and relabel it as "The Internet's top 100 name servers (by domains served)" (even in their own minds...), I just want to point out that there exists other TLDs on the Internet than those maintained by the InterNIC, and I know for a fact that some name servers in other areas would be included in your list if you had analyzed the data. Regards, - Håvard

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.) -- Rusty Hodge <rusty@hodge.com>, San Francisco

I know this is nanog, but there's more to the Internet than .com, .net and .org. Any chance of next level domains under .(net|or|org|co|com|etc).<country> and .<country> (for those that dont use (or|org|co|com) distinctions) being included in the same count? You'll see a number of these servers weighing in at 3 to 5 times these figures... (ie, there are servers that make it into your Top 200 on .com, .net and .org alone, where those domains only make up a minority of the domains delegated/served) Interesting, nevertheless.
