Question

Mac address and Ip address

Can someone help me out?

Is destination mac address for a dhcp Discover packet, broadcast?
and if so is it the same for a destination IP address?
Would destination mac address for dhcp request be unicast and the same for Ip?

Answer
A mac address

won't change but using DHCP the IP address does. Mac adress inindentify with the hardware and IP address in a networks adress. This is why when you purchase your own modem the ISP will connect using the mac address of the device.
