CAIDA Data - Overview of Datasets, Monitors, and Reports

CAIDA collects several different types of data 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.

This page provides a quick-access overview of available datasets (publicly available or otherwise restricted), with links to the dataset descriptions and access request forms when applicable.


The  colored header  in the overview table below indicates the field(s) the table is being sorted by. Click the header to change or toggle sorting order, and Shift+click headers to sort by multiple fields.

 Ongoing The data collection for this dataset is still active and has continuing, regularly scheduled collections.
 One-time snapshot The dataset comes from a single collection event that only occured once. Future events will have a different dataset name. See the Completed Datasets table for these datasets.
 Complete A formerly ongoing data collection that is finished, and will not be resumed. See the Completed Datasets table for these datasets.
Column Name Column Description
Name Dataset name
Status Current status of this dataset, indicating whether the dataset collection is ongoing or not. "One-time snapshot" implies complete. A link to resulting papers or analysis would be linked from the status, if available..
  • Ongoing - The data collection for this dataset is still active and has continuing, regularly scheduled collections.
  • One-time snapshot - The dataset comes from a single collection event that only occured once. Future events will have a different dataset name. See the Completed Datasets table for these datasets.
  • Complete - A formerly ongoing data collection that is finished, and will not be resumed. See the Completed Datasets table for these datasets.
Availability Public datasets are downloadable per the Acceptable Use Policy for the dataset. Restricted datasets require prior permission as well as adherence to the Acceptable Use Policy for that dataset. If a dataset requires a formal request for usage, the form will be linked.
Category Our taxonomy of the general category this dataset belongs in.
Source The source (e.g., network monitors, measurement infrastructure, etc) used to collect the dataset.
Start Date The date when the data collection started.

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.

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.
