METHODS

       _extract_iana_ip_blocks()
               my @array = _extract_iana_ip_blocks( $ip_version );

           Internal  method  that  is  used  to extract IP blocks details from IANA files for a given IP version
           (i.e. 4 or 6).

           Takes an integer (IP version).

           Returns a list of hashes - the keys of which are  "ip"  (Net::IP::XS  object),  "name"  (string)  and
           "reference" (string).
