The Bluetooth scanner can scan nearby Bluetooth devices and display their approximate distance, which can help you find lost Bluetooth headphones, Bluetooth mice, Bluetooth keyboards, and controllers. The app can scan and recognize the Mac address of local network devices, and by comparing with the cloud database, it can query the name and manufacturer information of the device. Many more devices, including smart TVs, game consoles, and smartphones have their own MAC addresses that you can find. You’ll see the MAC address listed under the Hardware tab. In System Preferences, click the Network icon, select the interface you want to use, then click Advanced.

The tools to check your MAC (and IP) addresses are different from system to system, note they only show your computers local addresses, not what can be seen on the Internet.One-click scan of inter-networked devices in the local network, can be used to find cameras, recorders, computers, etc. It’s also easy to find the MAC address on a Mac computer. However, if you are using IPv6 it might be possible that your IP Address can be generated using parts of your computers MAC address. This switcheroo happens on all routing points, so your ISP will take your packet, get the IP packet out and put it into another MAC packet and so on. When connecting to the internet your router will not use your computers, but its own MAC address to forward the packet.

Then there will be a protocol using for translating your friend’s IP address into MAC address and sending back to your computer. To change your network IP address in Windows. If you want to change the IP address of your internet connection, you should contact your service provider, as theyre the ones who exert control over this. The point at which your computers MAC definitely gets lost is when it passes your router, the router only transmits the IP packet to 'the Internet'. Your computer now needs to get the MAC address of your friend’s computer to recognize it’s the correct destination to send data. Note: This procedure changes the IP address of a computer on a wired or wireless network. I wont go too deep in here, bottom line is, it's only used for communication in your local network, be it cabled or wireless.

The MAC-address is part of the Link-Layer in the OSI Network Model.
