Yeah, unnumbered vlan subinterfaces (learning happens on DHCP), and cisco
itself does not send 'arp who has' on the wire. Very useful if you have
lot of low-speed subscribers on same rather empty subnet, to avoid
filling their pipes with useless 'arp who has' queries when someone
scans whole subnet through.

Thanks,
