AS CORE Visualization represents a macroscopic snapshot of the Internet for a two interval. The graph reflects IP addresses and IP links (immediately adjacent addresses in a traceroute-like path) of topology data gathered from 22 monitors probing destinations spread across globally routable network prefixes.

DNS CAIDA seeks to characterize the dynamics and performance of the Domain Name System (DNS), a critical infrastructural component of the Internet. We also collect data in support of long-term research of the DNS behavior and stability. To see more about CAIDA's DNS efforts, see the DNS Research page.

IPv4 BGP Geopolitical Analysis The worldwide distribution of Internet resources and address space is highly non-uniform. We present an analysis comparing five demographic measures against three measures of Internet resources, stratified by continent with substratification by country. We found that two continents and one country consume a much larger share of Internet resource allocation than predicted by their demographic measures of size. For more information see IPv4 BGP Geopolitical Analysis
