DNS Site Operator
December 1st, 2002
This report details the names and locations of all DNS servers
on the internet, as well as the number of domains that are serviced
by these servers. In this fashion, we can discover
- the number of sites hosted by ISPs
- the number of sites hosted by hosting companies that use an ISP's
facilities, but run their own name servers
- the number of sites hosted by specialty DNS service providers
- the organizations that choose to operate their own DNS servers
rather than to use those of their ISP/hosting provider.
The survey works by determining each month the authoritative name
server for each host (and more accurately, each domain) in our
survey. We then count the number of domains hosted on each
DNS server.

Curious about the size of a the domain set handled by a particular
ISP's name servers? Try searching for the ISP's name server. For example,
to find Exodus' name servers, try exodus.

Survey Limitations |
 |
Our survey, while having an impressive 9,143,959
sites and 5,322,729 domains in the
data set, does not include all web sites and domains. We only include those
that we consider active, which, by our definition, means
we found the site via a link from somewhere else. Sites not linked
by anyone are by definition not included in the survey.
We also actively drop sites out of the survey that fail to respond
3 consecutive months to our HTTP queries. So, while a DNS server
might still respond with information for a domain, if there is no
active web site that we can reach for the domain in question,
then the domain is not included in this survey at all, even if it
still has other functioning services (such as email).
