First, right-click on the Start menu and select the Command Prompt option 2. However, you will need to manually type in information and be able to sift through the results. It also requires the least number of steps. There is no database tracking the geographic location of MAC addresses. Finding your MAC address using the Command Prompt feature is the easiest way to locate the required information. Given that information, you can either try searching the machine room to see if there's an XyZZY Networks box with the IP address 192.9.200.66 labeled on the front (or search whatever the manufacturer and IP address are), or can ask the network staff where that router is. Try searching the IEEE database of MAC registration blocks for the XX:YY:ZZ part - but replace the colons with dashes for some reason, the search engine won't do that for you. In addition, the XX:YY:ZZ part might help you determine who made the router. Which says that the MAC address for the IP address is XX:YY:ZZ:UU:VV:WW if the MAC address you have for the router is XX:YY:ZZ:UU:VV:WW, you now know one of the IP addresses of the router, in addition to the MAC address you already knew.

That will print the machine's ARP table, which may have an entry of the form XXX () at XX:YY:ZZ:UU:VV:WW. If you have a machine on the same LAN segment as the router, using the router to communicate with other machines, and it's running some flavor of UN*X or Windows and you have access to its command line, try running the command arp -a. How would I use MAC address to locate routerĪssuming you mean the MAC address of the router (the MAC address of any other machine won't help): As you can see, the sh arp or sh ip arp commands also give you the MAC addresses, so essentially the sh mac add is only to get the port in which the device is connected.
