CAIDA Topology Datasets (14)
Internet topology is visualization of the arrangement and interconnectedness of devices within the autonomous systems (ASes) of the Internet at a large scale. Internet topology maps are an important tool for those who seek to describe, analyze, or model various aspects of the Internet‛s structure, behavior, and evolution.

ASes and Orgs 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..

PeeringDB, an online database of peering policies, traffic volumes and geographic presence of participating networks. PeeringDB, a non-profit member-based organization, has been established to support practical needs of network operators. However, it is also a valuable source of information for researchers. The first version of PeeringDB resided in a MySQL database, which was not scalable and lacked security features and data validation mechanisms. It presented potential risks of exposing contact information to spammers, and contained typos. Starting at the end of March 2016, PeeringDB switched to a new data schema and API.

CAIDA DNS Datasets (3)
DNS (Domain Name System) is the system which translates human-readable web addresses to computer-readable IP addresses, enabling the proper routing of internet traffic. DNS names are useful for obtaining additional information about routers and hosts making up the Internet topology.

External (non-CAIDA) Data
Other organizations across the globe, both academic and non-academic, provide access to internet-related data that also are of interest to the research community. Links to several of the more interesting datasets are given in a non-exhaustive list of external (non-CAIDA) data.
External (non-CAIDA) Publications using CAIDA Data
We maintain a list of publications from research using CAIDA data. The purpose of this list is to provide insight into past uses of CAIDA data. We rely on researchers who download our data to comply with the Acceptable Use Policies of CAIDA datasets in reporting published papers and presentations to us. See this list of Non-CAIDA Publications using CAIDA Data.
Report a Publication using CAIDA data
Users of CAIDA data agree to an AUA to notify CAIDA when they make a publication using CAIDA data. Report a publication using CAIDA data by completing the form or emailing data-info@caida.org.
