Question 1: unicast oui MAC address in the first byte of the eighth bit types to address, for host MAC address, this bit is fixed for 0.
This address type to point to? Fixed 0 mean that this is a unicast frame, only destinition MAC receiving process?
Question 2: broadcast frames MAC address for the purpose of hexadecimal FF: FF: FF: FF: FF: FF,
Not all of the source host sends a message to all of the Shared destination? Destination MAC address should all be Shared host MAC address, how could you run a FFFFFFFF? The novice trivial pursuit, give advice or comments!

Question 2:
Principle is the broadcasting of local area network (LAN), any a machine frame, the network of all the machines will be received,
Unicast is the principle of the machine after receiving the message, the inside of the destination address and their comparison, the same, different is discarded,
Ff: ff ff ff: ff: ff is a special address, destination address value for this machine received frames, to accept all the frames

Thank you and look after the IP addressing understand, ask which position do you think about the big network is promising? Network security? Is there anything else?

I don't know much about it, looking for a job half the strength, half the opportunity, learn more no harm anyway
