Try this
For Each nic As System.Net.NetworkInformation.NetworkInterface In System.Net.NetworkInformation.NetworkInterface.GetAllNetworkInterfaces()
If nic.OperationalStatus = Net.NetworkInformation.OperationalStatus.Up Then
MessageBox.Show(String.Format("The MAC address of {0} is{1}{2}", nic.Description, Environment.NewLine, nic.GetPhysicalAddress()))
End If
Next

It depends on the machine. However, the MAC address is usually found in the network interface properties.
The source Mac Address, from which machine it is being transmitted.
Yes, it's possible to spoof a MAC address.
The "MAC" address of your computer is built into the Ethernet board.
This is a unique machine ID, also known as 'Mac Address' in terms of networking.
ARP Spoofing
Use ip\mac scanner: http://trogonsoftware/trogon-mac-scanner.html
No, they can't have the same mac address, because mac address is an id for a machine therefore the ip addresses are registered to the DHCP table accordingly to the mac address. So if you spoof the mac address lets say having two machines with the same mac address what will happen is that only one machine at time would be allowed once it disconnect then the other can connect. Why spoofing a mac address? I guess one of the reasons is to defeat a network administrator when they secure their network by filtering the mac addresses so by spoofing the mac address you will be able to access the internet.
''ipconfig/all''
ARP
When sending information over a local area network, to a specific computer, the MAC address of the destination must be known. ARP - the address resolution protocol - takes care of that. With it, you can ask for the MAC address that corresponds to a specific IP address.
An ARP request may be initiated anytime a client needs to know the IP address of a machine from its MAC address.
