#' Digital Ocean ranges
#'
#' Digitial Ocean (cowardly) doesn't publish their ranges, so we have to approximate with
#' known Digital Ocean ASNs.
#'
#' It is unlikely that this list will change in your analysis session, so it is
#' recommended that you cache the results. Future versions will automatically cache
#' the results both in-session and on-disk for a period of time.
#'
#' @note ASN list current as of June 2018
#' @return character vector of IPv4 ranges
#' @export
#' @examples
#' ranges <- digitalocean_ranges()

#' normalize_ipv4(ranges)
