CAIDA UCSD IPv4 Prefix-Probing Traceroute (2015-12-09 to 2020-01-01)

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).
