SYNOPSIS

          my ( $asnref, $prefix, $raw, $ret_code ) = Zonemaster::Engine::ASNLookup->get_with_prefix( '8.8.4.4' );

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.
