CAIDA Internet Data -- External Data Sources

CAIDA collects several different data types at geographically and topologically diverse locations, and makes this data available to the research community to the extent possible while preserving the privacy of individuals and organizations who donate data or network access.

To keep up to date on CAIDA datasets you can subscribe to data-announce@caida.org. For other questions about CAIDA data, please contact data-info@caida.org.

CAIDA is not the only group that provides researchers with access to internet data sets. Below we provide a non-exhaustive list of these external (non-CAIDA) data resources. An Overview of CAIDA data resources is available on the CAIDA Data - Overview of Datasets, Monitors, and Reports page.

External Data Sources

Packet Clearing House	Associated Data
The Packet Clearing House provides educational information, including data relevant to network research, to the public. PCH houses an exchange point list and a routing table archive similar to RouteViews.	PCH PCH Exchange Point List PCH Routing Tables
RIPE (Réseaux IP Européens)	Associated Data
As the European Internet Registry, RIPE maintains one of the WHOIS databases connecting IP address information with address owners. In addition to this operational responsibility, RIPE also collects time-synchronized active measurements (including delay and IP path) as a part of it's Test Traffic Measurement (TTM) project. RIPE is also developing an Internet Number Resource Database (INRDB) that indexes the RIPE NCC databases and other entities.

University of Brescia	Associated Data
The University of Brescia (UNIBS) stores traces collected by their Ground Truth (GT) software suite.	UNIBS Data Sharing
University of Oregon RouteViews	Associated Data
The University of Oregon RouteViews Project collects routing tables from a large number of peers and records them every two hours. RouteViews is useful both for research and operationally as it allows users to see what address prefixes are announced and how those announcements have propagated through the Internet.	RouteViews
The Waikato Internet Traffic Storage project	Associated Data
The Waikato Internet Traffic Storage (WITS) project contains all the Internet traces available at the WAND Group of the Univ. of Waikato in New Zealand. Some of these trace sets are now available to researchers. It includes passive traces from the former NLANR research group (e.g., the NLANR PMA Auckland Datasets, and AMP topology data).

Measurement and Analysis on the WIDE Internet (MAWI) Working Group	Associated Data
The MAWI Working Group has carried out network traffic measurement, analysis, evaluation, and verification from the beginning of the WIDE Project.	MAWI Working Group Traffic Archive
The IRCache project	Associated Data
One of the primary goals of the IRCache project to provide relatively large amounts of trace logfile data to researchers and other organizations. Among the data provided are sanitized HTTP logs.	Weblog traces
Internet Research Group at Eurecom	Associated Data
Has links to results of crawling the peers in the region 0x5b of the KAD peer-to-peer for almost half a year every 5 minutes; and the full KAD network for more than one year once a day.	Full KAD traces
UMass Trace Repository	Associated Data
Links to a variety of traces either collected at UMass or donated.	UMass Network Traces
