here is my problem... I’m managing my local Wi-Fi network and I wanted to reserve some IP addresses to important devices, such as the local printer in my house. It’s a simple task. I only needed to know my printer’s MAC address and reserve it to a specified IP address (192.168.1.50) within my routers configuration interface. The problem is that I checked my DCHP clients list and I noticed that many of the devices listed didn’t have the correct MAC address. In fact, they were slightly modified. For example: My printer’s MAC address (the real one printed on its back) is C4-34-6B-2D-5E-04. In my router’s webpage, my printer’s MAC address is 02-0F-B5-2D-5E-04. For some reason, my router changed the first 6 numbers, so my address reservation couldn’t work. The same thing happened to some of my other devices. Their MAC address in my routers interface client list is not the same specified by the manufacturer. The first 6 numbers were also changed to 02-0F-B5-XX-XX-XX. Here is what my client list looks like:
Notice that many of them have their MAC address’ first 6 numbers changed to 02-0F-B5… and the rest being correct. Also, something very strange, sometimes I get the same client getting two MAC addresses. One is slightly modified (6 first numbers) and the other one actually corresponds to the real MAC address. For example, look at clients ID 2 and 6. They have the same Client Name but different MAC Addresses. Would you know why this is happening? Sometimes, when I reboot the devices, the real MAC address is listed and so my address reservation works, but it’s kind of random. My router’s model is a TP-link TL-WR1043ND. Thanks everyone!
