To me, that means they can assign it when, and to whom, they wish; but that for now it is not a real internet IP block.

My firewall DROPs all IANA Reserved networks. -- gypsy _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
