hostcount for February 1995

Dear all,
Here is the hostcount for February 1995.
The hosts in the following domains are now counted locally:
at be cy cz de fr gr ie il it pt sk uk
I made two hostcounts for February: one was calculated in the
usual way and the other was calculated incorporating the local counts
for the domains above. I made some comparisons between the two sets of
data and have published only the latter.
When the hosts are counted centrally a significant number of zones are
missed and not included in the total numbers.
It seems clear therefor that the results are more reliable if they are
produced locally for each domain.
A few countries have made big increases again, to a total
increase since last month of over 91,000 (or 8.3%) to almost 1,200,000
machines in the DNS in Europe.
There is one thing to note about the de domain:
It shows an enormous increase since last month.
The person responsible for the hostcount in Germany did some research on
that and found a zone with the following kind of A RR's:
host.x.y.z.1. a x.y.z.1
host.x.y.z.2. a x.y.z.2
host.x.y.z.3. a x.y.z.3
host.x.y.z.4. a x.y.z.4
host.x.y.z.5. a x.y.z.5
host.x.y.z.6. a x.y.z.6
host.x.y.z.7. a x.y.z.7
host.x.y.z.8. a x.y.z.8
[...]
65,000 A RR's.
In the actual hostcount are only 25,000 A RR's included because the
host command contains a limit for hosts per zone:
*** maximum of 25000 hostnames reached
This implies that you can add another 40,000 hosts to the figures for the
de domain.
This incident shows what the hostcount actually represents:
Technically, it is a count of A records in all zones
that could be retrieved. Heuristically, it gives an approximate
overview of the current machine population.
This should remind us to be careful with the objectivity of the hostcount
and the purposes we use it for.
The hostcount can also be found under ftp.ripe.net/ripe/hostcount
If you have any comments or questions please do not hesitate to contact me.
Best regards,
Mirjam
