I have a few questions, but all under the same umbrella topic:
If I find out a MAC address of a machine on a LAN, and I spoof my MAC to match that particular machine and join their LAN, how will things in the network behave?
I read something that lead me to believe IPv6 has MAC addresses "encoded" in them. Am I wrong in this interpretation? Would it be very bad if someone knew my IPv6 address - could this give them my MAC address also?
Can I get a legal programmable NIC that lets me change its MAC?
Do phones have an equivalent to MAC addresses? I heard it was UUID, but I wasn't sure.
