Caches & Returns the latest CAIDA-processed RouteViews "Prefix-to-AS" File

CAIDA maintains current & historical IPv4/IPv6 Prefix-to-Autonomous System (AS) mappings that have been derived from RouteViews data. This function figures the most current file, caches it and returns a data frame.

routeviews_latest()

Value

a data frame (tibble) with "cidr" and "asn" columns.

Details

You can see available, historical files via list.files("~/.routeviews") and read/parse arbitrary prefix-to-AS CAIDA RouteViews files with parse_routeviews().

See the datasets repository for usage and citation information.

Note

A "~/.routeviews" directory will be created if it does not exist.
