This is the same cache which give 'IP resolution conflicts'. How can you find the MAC for a particular IP(machine) which is not the part of your subnet?įor the all the machines/IPs on your subnet the IP-MAC table is stored in ARP Cache, locally on your machine. They will always return MAC address as 00-00-00-00-00-00. The above technique wont work on Linux samba servers. But if network has lot of Linux machines then there is no good very common way to find MAC from other networks. Hence if there are lot of windows machines on your network you can find MAC address for them even when are not in their subnet. But I guess you have to be administrator for accessing router or DHCP server. Then the only options are seeing MAC address table in router, or if there is common network wide DHCP server then you can see MAC address in DHCP logs. If the machine in question is not a windows machine and there is no way to become part of other subnet. To do the same thing from Linux machine (with samba installed) use command nmblookup -R -S -A For example to find MAC address of a Windows PC on other network when you know its IP address you can use command nbtstat -A But there are some protocols that may help you in finding MAC address from anywhere in network.

When finished, type Exit then press enter to close the command window.It cannot be guaranteed that you can see MAC address of machines behind a router.

At the prompt in the open command Window: Type getmac /v: The MAC address, labeled 'Physical Address,' will be displayed in the form xx-xx-xx-xx-xx-xx:.

(Click Start, Run, Type CMD, then right-click CMD.exe on the menu, and click Run as Administrator) To locate the MAC address of a NIC in Windows, follow these steps: Issue 2: Locating the MAC Address of a NIC in Windows The instructions in this article explain how to do so.
