Mac Address Tracking Software

Posted on  by admin

Finding the owner of a MAC address isn't so straightforward

Computer manufacturers and people who buy computers do not register their MAC address with any sort of central administration.
There isn't a way to find a stolen computer from the MAC address or to find the identity behind one of these addresses. Much like IP addresses, MAC addresses are assigned to network devices and are easy to determine with tools like Command Prompt. On the other hand, they're unlike IP addresses in that they can't be researched to find the owner.

Although MAC addresses are not filed away somewhere with identifiable information attached to them, there are ways to search for a MAC address to find more information about it.

What you find might help you further investigate and troubleshoot.

For example, use the website MAC_Find to look up a MAC address to find its vendor information.

MAC Address Searching

If it works, you're one step closer to learning more about the manufacturer, but it doesn't really help in a search for finding who owns the MAC address. On a local network, the arp command with the -a switch identifies the MAC address of a connected device.

MAC Addresses Blocking

It works if you know the IP address. You can also try arp -a by itself to get a list of IP/MAC combos. Search for the MAC address you have to tie it to the IP address, and then run the tracert command with the IP address to identify the device's hostname. While blocking a MAC address won't be helpful if your computer was stolen, it can definitely come in handy if someone is stealing your Wi-Fi. When you block a MAC address, what you're really doing is explicitly allowing only certain MAC addresses to connect to your network. You can block MAC addresses through what's called MAC address filtering. The moment you implement this on your router, anyone using devices that don't comply with your approved listing of MAC addresses, are immediately kicked off your Wi-Fi. Search a cell phone, laptop, or wireless router online using 2 MAC addresses and find its location on Google Maps. Please note, you need two MAC addresses in the same area to make this WiFi tracker work, otherwise it might not return any location.
