Is it possible for MacOS X (current version or in any previous one) to easily force DHCP client to send to DHCP server, at the beggining of the conversation - in DHCPDISCOVER packet - option "Vendor Class Identifier" (60) set to some value? I know that I can install i.e. ISC DHCP client through pkgsrc which supports VCI, but I'm looking for something native. Thank you in advance for information.
