Step 1 Open the Linux terminal and run the following command: ifconfig -a. So MAC address cannot be used to track a devices location. If you are running the application under a domain admin account, it may be possible to connect to every computer's WMI system (Windows only) and retrieve their MAC addresses. For the Linux system, follow the below steps to find IP and Mac addresses. MAC address is only used within its LAN, it is not forwarded through routers. The router may need to be specially configured to provide this information via SNMP. So it works for both local and non-local subnets. Once the Engineer toolset is launched, go to Network Discovery on the left-hand side. As the router sits between two subnets, it knows client MAC addresses on both sides. To start off, you will have to open up the Engineers Toolset Launch Pad. The downside here is that only the computers that support the NetBIOS protocol will respond with their MAC address. This method sends a special NetBIOS packet to the target computer, which works for both local and non-local subnets. The reason is that routers do not pass ARP messages from one subnet to another.

This method always works in the local subnet, but it does not work with non-local subnets. One of the best free ones is called IP Scanner which is free (on home networks for up to 6 devices) and presents all the information in a convenient list such. These are a Ping scan, an SNMP scan, a MAC address scan, and a DNS scan. The tool offers several scanning options. This is the basic requirement for any IP address tracking exercise. A few devices that support NetBIOS will respond with their MAC address, but not all of them.Īs there is no single, universal method for resolving MAC addresses from a different subnet, Network Scanner has four relevant settings under Options – Program Options – Additional: The Free OpUtils includes the IP Network Scanner, which checks on each IP address’s connection/usage status. You may still see some MAC addresses as the scanner attempts to use the NetBIOS protocol when ARP is not available.
This is also why MAC addresses from a different subnet are not displayed. The reason for that is the fact that a router residing between subnets cannot pass ARP traffic through. Scanning a different subnet is similar to scanning the local subnet, except the Address Resolution Protocol (ARP) used for resolving IP addresses to MAC addresses does not work across subnets. MAC Address Scanner is a small utility used to scan the network and determine the MAC addresses of the computers on it. An easy way to get a list of MAC to IP addresses on the local subnet is to ping every host on the subnet and then check you ARP cache, however pinging.
