At that time,ARIN’s Internet Routing Registry (IRR) followed a weak authorization model compared to available and in use today such as RPKI.

The consumer needs to enter into a ‘Bulk Whois Data’ agreement with ARIN, download a multiple-gigabytes XML file (which is only generated once a day), parse this XML, and then extract the OriginAS field.
