Abstract

By the end of 2008, China has 298 millions of Internet users served by 214 ISPs. But little is known to researchers about the details of these ISPs. In this paper, we try to understand web hosting utility of Chinese ISPs. After a brief introduction to ISPs in China, we use a simple and general method to uncover the web hosting information of ISPs including websites and web pages they host. We present a metric to evaluate the web hosting utility based on a new model which relies on public available data. Finally, a ranking of Chinese ISPs is given according to their web hosting utility. We analyze this ranking from the point of view such as IP allocation and geographical features. We believe that results of this work are not only helpful for researchers to understand networks in China, but also beneficial to interdomain capacity planning in China.
