![]() There is no database tracking the geographic location of MAC addresses. Download Wireshark Now The worlds most popular network protocol analyzer Get started with Wireshark today and see why it is the standard across many commercial and non-profit enterprises. How do we find such host information using Wireshark We filter on two types of activity: DHCP or NBNS. 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. If you have access to full packet capture of your network traffic, a pcap retrieved on an internal IP address should reveal an associated MAC address and hostname. Instructions in this article apply to Wireshark 3.0.3 for Windows and Mac. Because it can drill down and read the contents of each packet, it's used to troubleshoot network problems and test software. 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. What to Know Wireshark is an open-source application that captures and displays data traveling back and forth on a network. 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):
