A lot -- possibly even a majority -- of the cards I saw operating in ad-hoc mode were using mac address prefixes that aren't assigned to any manufacturer by the IEEE [1]. Many started with the octet "C0". I even saw a card in ad-hoc mode with a MAC address of FF:FF:FF::FF:FF:FF. /a [1] According to http://standards.ieee.org/regauth/oui/oui.txt which is updated daily.
