These data result from CAIDA's traceroute-based measurements running on the Archipelago (Ark) measurement infrastructure (also see CAIDA's Macroscopic Topology Project). We use BGPStream to gather announced BGP prefixes from RIPE and RouteViews BGP data. Each day, we derive a new set of announced prefixes using a sliding window of 7 days of BGP data (7 days of data ending on the day on which a daily BGP prefix set is generated). For each announced prefix, we generate a single target address, ensuring there is never more than one target address in any prefix despite the presence of overlapping prefixes (that is, more specific prefixes).

Data availability

• Data older than one year is available as a public dataset. You can obtain access using this form.
• The most recent one year of data is available for use by academic researchers and US government agencies. This data is also available for corporate entities (including corporate researchers) who participate in CAIDA's membership program. Please, complete and submit the online form to request access to the most recent data. It usually takes about two to three business days to process your request. Upon approval you will receive an email with instructions on how to download the data you requested. If you have any questions or problems using this form, please contact data-info@caida.org.
