This visualization represents macroscopic snapshots of IPv4 and IPv6 Internet topology samples captured in January 2015. For the IPv4 map, CAIDA collected data from 118 monitors located in 42 countries on 6 continents. For the IPv6 map, CAIDA collected data from 47 Ark monitors located in 25 countries on 6 continents.

We are now deploying small, inexpensive network measurement nodes, based on the Raspberry Pi, in the Ark measurement infrastructure. Although tiny, a Raspberry Pi is as capable as a desktop system of several generations ago and offers a flexible Linux-powered programmable platform for conducting networking research. These systems can be placed anywhere that is convenient for a hosting site, including on someone's desk, and the transition from deploying traditional rack-mounted servers to Raspberry Pi's will allow us to scale up the Ark infrastructure.

We present the BETA version of AS Rank, CAIDA's ranking of Autonomous Systems (AS) (which approximately map to Internet Service Providers). This ranking is derived from topological data collected by CAIDA's Archipelago Measurement Infrastructure and Border Gateway Protocol (BGP) routing data collected by the Route Views Project and RIPE NCC. ASes are ranked by their customer cone size, which is the number of their direct and indirect customers. Note: We do not have data to rank ASes (ISPs) by traffic, revenue, users, or any other non-topological metric.

We explore common properties of complex networks in order to find a general mechanism that would support a structural model of the network explaining the connection between network structure and function. Our proposed mechanism relies on the presence of a metric space hidden behind an observable network, referred to as the Hidden Metric Space (HMS).

A visualization of IPv4 address space. Using the results of a census taken by the LANDER project that probed every IPv4 address with an ICMP echo request (ping) packet, and mapping 1-dimensional IPv4 address space into a 2-dimensional image, the resultant census map can give some indication of how the Internet's IPv4 address space is being used.

The DNS workload animated maps show the number of queries and clients seen by one of the .CL nameservers in Chile and its hourly variation along two days of traces beginning on July 3rd 2007 at 21:00 (UTC). The animation provides a view of the world map and colors countries based on the load that each country originates.

This visualization shows the geographic distribution of DNS clients for anycast instances. We provide two world maps for each root, with individual anycast servers placed on the map at the "center of influence" of its observed clients. Wedges fanning out from each server indicate the direction, distance, and number of clients observed within the bounding angle of the wedge.
