What things can I do with MAC address?

Wireless access points often use MAC addresses for access control. They only allow access for known devices (MAC address is unique and identifies devices) with the correct passphrase. DHCP servers use the MAC address to identify devices and give some devices fixed IP addresses.

What can be tracked using MAC address?

You cannot identify a specific device by its MAC address online. The MAC address doesn’t travel far enough to be useful for location information, and there’s no central database of which MAC address is assigned to what device.

Can you access a device using MAC address?

How can I access a device by MAC address? The easiest way to access a device, knowing the MAC address is to use the arp -a command to find the related IP address. With this address, you can access the device using Remote Desktop Management, a Telnet program, or some other connection facility.

Why do devices need the MAC address of other devices on the network?

MAC addresses are required to make a local Ethernet (or wifi) network function. They allow a network device to attract the attention of a single directly connected device, even though the physical connection is shared. This can be important when thousands of devices are connected together within a single organisation.

What I can do with someone’s IP address?

With someone’s IP address, you can learn a user’s general location, and disable some parts of their internet browsing experience. Every device connected to the internet has an IP address, which helps websites identify your computer.

Is it safe to share MAC address?

Probably not. The MAC address is a unique 12 character string assigned by the manufacturer. Unless your device has been granted access to some secure network based solely on its MAC address… giving it out should not be a problem.

What device does this MAC address belong to?

How do I find my MAC address? The easiest way to get your Mac address under Microsoft Windows is to open the command line or Powershell and enter the command: ipconfig /all. The now displayed Physical Address is the MAC address of your network device.

What can you do with a routers MAC address?

A DHCP server (like your router) uses a MAC address to assign an IP address to a network adapter. Without MAC, an adapter can’t get an IP address. Without an IP address, the device can’t connect at all. You can also use the MAC to reserve a particular IP address for an adapter within a local network.

Why do we need both MAC address and IP address?

So again, IP Addresses are logical and routeable addresses. And that’s why computers have both MAC Addresses and IP Addresses. MAC Addresses handle the physical connection from computer to computer while IP Addresses handle the logical routeable connection from both computer to computer AND network to network.
