We find that as much as 60% of the Web servers are co-hosted with 10, 000 or more other Web servers, indicating that the Internet contains many small co-hosted Web servers. Likewise, more than 95% of Web servers share their AS with 1000 or more other Web servers. We additionally find that heavily co-hosted Web servers contribute much less traffic than Web servers that are not co-hosted, confirming that popular servers are not co-located, while less popular servers co-locate more frequently. When considering block lists, we find the vast majority of blocked Web servers are hosted on IPs hosting 100 Web servers or more. This indicates there may be a great deal of collateral damage with IP blocking. Finally, when looking at authoritative DNS servers, we see a high degree of co-location on a very small number of DNS servers, which may result in the Web being fragile from a DNS perspective.
