I'd like to create manually a DHCP packet and send it as a broadcast. I already can do it from a PC by preparing a packet and sending it to my local DHCP server. However, this packet contains a MAC address of a device. The question is: what should this packet contain instead of MAC address in case of a mobile phone? IMEI? IMSI? As far as I know, phones don't have a MAC address for a GPRS connection (I don't mean WLAN).

Thanks in advance,
