_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).
