Usage of CAIDA Public Online Datasets

CAIDA provides public online access to several datasets. Users interested in downloading these data are asked to fill out an optional user-info form, where among other items they provide an email address. The number of submitted user-info forms are used to count the number of users of public CAIDA data. The TLDs in the email addresses are used to obtain the geographic distribution of users of CAIDA public datasets.

Geographical Distribution of Users of Public Data

We use the TLD extracted from the email addresses provided by users that download public data to get an overview of the type of user (e.g., educational, commercial, government, etc.) and, from country-level TLDs, their geographic distribution.

The table shows the total number of users for each TLD encountered.

The graph shows the TLDs and countries most often encountered over the years.
