Survey Data Mining: Home | FAQ | Archive | Glossary |
Web server surveys have been around for a long time. One of the problems with running a survey is how to produce meaningful results given the number of choices with the collection and reporting methodologies. Some examples:
This particular report addresses this in part by counting unique IP addresses in an attempt at answering the question of how many installations of a particular server might exist. By using the IP address as a proxy for the physical hardware on which a server is running, we still need to be aware that it is not a perfect 1 to 1 mapping:
While not a perfect solution, we feel that counting web servers by IP will give a much closer view of the number of server installs for a given technology.
