FUNCTION

       get($addr)
           As get_with_prefix(), except it returns only the list of AS numbers for the address, if any.

       get_with_prefix($addr)
           Takes  a  string  (or a Net::IP::XS object) with a single IP address, and does a lookup in either: a)
           Cymru-style DNS zone or b)  RIPE  whois  server,  depending  on  Zonemaster::Engine::Profile  setting
           "asn_db{style}".

           Returns  a  list  of a reference to a list of AS numbers, a Net::IP::XS object of the covering prefix
           for that AS, a string of the raw query, and a string of the return code for that query.
