Re: New Document available: RIPE-271

Here in HEAnet, we've been working with RIPE to perform the hostcount for .ie since before there was a RIPE or a HEAnet:) From this point of view, we have some comments on this new document.

Despite the title of document RIPE-271, the term 'hostcount' seems to be used purely to provide an extended historic baseline for the statistical work of RIPE NCC. The document is silent on proposals to improve the quality of the hostcount and, thereby, the integrity of the DNS. There is still a lot of useful information, for statisticians, planners, DNS hostmasters and the general public, which is made available from the analysis of the hostcount so it is a shame that the document concentrates only on TTM and RIS.

Although it cannot be inferred that this is the intent, if the principles of openness outlined for TTM were to be extended to the hostcount, it would undermine previous assurances given by RIPE that the raw hostcount information would not be generally available - In our experience, it is this assurance that has encouraged people to permit zone transfers to the IE collector who otherwise would not have so done. To remove it at this point would undermine the integrity of RIPE in the eyes of those working under that assumption at the moment and even fewer would be likely to facilitate the hostcount in the future.

Short content description

RIPE NCC Hostcount in the 21st Century
A New Direction for Measurements by the RIPE NCC

The RIPE NCC has collected data and published statistics
from its inception. In fact the hostcount has even started
before the RIPE NCC began operations. Other measurement and
data collection activities have been added later, most
notably Test Traffic Measurements (TTM) and the Routing
Information Service (RIS).

After more than 10 years it is time to re-visit this area
and adjust the direction based on input from the RIPE
community and the NCC membership. This memo proposes the
new direction and seeks to establish consensus among the
RIPE NCC membership.
