I agree with Thor here - what are you trying to accomplish here? Why don't just check your IP address/network mask (if you're located on the same L2 network as your target), and then start ARPing (not 'arping', mind you) for all the other addresses on the same range? Match source MAC to your desired MAC, and will find out the IP address assigned to that MAC. Caveat: there could be more than one L3 network running on the same L2 network - and you would need to repeat the process for every L3 network you want to find the remote IP address for. Technical note: there *is* actually an RFC to do what you want to do - RFC-2390, 'Inverse Address Resolution Protocol'. While it is not dependant on the underlying L2 technology in use, AFAIK it has only been implemented on ATM and Frame Relay networks - so, out of luck here. Personal note: it seems you got some answers suggesting for you to get an book on OSI and layers, and how the whole thing works. Don't take it as an affront, but as a general suggestion that might help you down the road. One such 'free' book that I wholeheartedly recommend is "TCP/IP Tutorial and Technical Overview", a RedBook from IBM, which you can download for free from http://www.redbooks.ibm.com/abstracts/gg243376.html?Open - I keep a copy all the time on my notebook, and has helped me to look up some concepts while away from the office and without access to my Comer or Stevens copy :) Thanks, Dario

ARP resolution of the MAC to the actual IP will only work if you are on the same subnet as the host--otherwise you'll get the default gateway's MAC when resolving the IP address. Given that, if the host *is* on the same subnet, and you want to reach it, it doesn't really matter what IP address is bound to the adapter-- you can just add a static ARP entry on the local system to assign the MAC to whatever "in-network" IP you want, whether it's the "real" IP or not... t -------------------------------------------------------------- ---------------- Audit your website security with Acunetix Web Vulnerability Scanner: Hackers are concentrating their efforts on attacking applications on your website.
