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 Below the DNS hostcount for September 1992.
Remarks:
- CS has a low count this month due to network reachability problems. I have
tried two times more to count CS, but with the same result.
- IT also has this problem, a few hundred hosts less due to network
reachability problems.
- PT has the same problem, although on a smaller scale. Also tried two
times more, with the same result.
- DE really takes off now, they are the first to reach 50,000+.
- Overall another nice increase of just over 10,000 to reach 230,000 plus.
- This count was done a bit earlier in the month than usual, but I needed the
output for our 2nd Quarterly Report, and for the coming RIPE meeting ;-)
- Next month we will start doing some tests with distributed counting. Some
people have agreed to do the count for their own country within the country,
and make the results available to me. This should decrease the influence of
network and link outages, and increase the count even further.
- All output can again be found on ftp.ripe.net:/ripe/hostcount. Check the
README for details. Previous counts 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
