1) ARP for the MAC address associated with a given IP address (*). Call the result "m". 2) Now, once again ARP for the MAC address, calling the result "m'". Question: under what circumstances will m = m'? If your code lives in a world where those circumstances will always apply, then for your code, there is a relationship between IP address and MAC

Sorry for the cross-post :p OK, in Linux I can obtain the MAC address using socket(), ioctl() etc. and a few data structures. No problem. However, the resulting MAC is stored in a 14 byte char array (sockaddr.sa_data). However, a MAC address is 48-bits! The MAC (as in the char array) is obviously the printable form of: 00efc8346b72 or whatever. Fills the supplied buffer with the MAC address of the device.
