How to determine MAC address given an IP address?

[M A V]

I have IP address of the computer in a network. How can I determine it's MAC address ? :confused:

Go to run and type "cmd" (without the quotes) once in the command prompt type "ipconfig /all"....the will give your IP MAC DNS.....etc

I know how to get it manually of course. :)

But since this fourm is named "Visual C++ Programming" i am asking: "How to do this in Visual C++ ?"

If you try to determine the Mac Address of a local Computer you can use
GetAdaptersInfo from the IP Helper API.
The IP_ADAPTER_INFO structure contains the member
Address which contains the MAC Address as Bytes.
For remote computers which have already contacted your PC you can try to read
out the ARP cache with GetIpNetTable. This list contains a structure member named bPhysAddr which contains the MAC address.

Hope this helps a bit.
