My only comments about this site are steeped in awe over both the spectacular organization and the staggering amount of data it makes accessible.  This is clearly a site intended as an information source and, likely, also a facilitator of community for those working to understand the structure of—and data transmission via—the internet. While some of the labeling is so standard as to be comprehensible by the absolute layman (myself), I expect the abundance of acronyms and field-specific language used to present the collected data (and its interpretation, in papers and other formats on the site) do well to keep the novice at a distance. As for the actual content, I’m not sure I understand some of the maps like the IPv4 & IPv6 Topology Map – is this meant as a snapshot of internet traffic as routed through only a certain number of monitors, or is it meant to represent all internet traffic?
