RIPE DNS Hostcount

This document is obsoleted
Hi folks,

better late than never here is the July host count. I did not take as
much time as Marten usually does to re-count unreachable nameservers, so
the count may be a little low. A list of domains for which no servers
responded is attached below.

Generally one can say that growth continues as expected. There are
still a lot of networks referenced which are not in the RIPE database.
Please spread the word about the database in your vicinity.

I have also heared quite some implicit and explicit critisism of the
counting and the numbers published. They have been called "wild
guesses" and "unrealistic estimates". Just to make it perfectly clear:
We count all hosts registered in the DNS. There is no guessing
involved. Files which list all hostnames counted can be found in
directory ftp.ripe.net:~ftp/ripe/hostcount which is accessible via the
usual RIPE document store access methods. Since usually some nameservers
cannot be reached at the time of the count the numbers are actually
a lower bound of the real number of hosts registered.

Another critisism has been that the count uses network bandwidth which
could be used for more useful things. The answer to that is that we
count during the weekend when in most regions of the net there is
sufficient bandwith for all applications.

For DNS administrators it might be a good idea to look at the error
files in the hostcount directory mentioned above. It might give you
some suggestions for improving your DNS setup.

Regards

Daniel
