MAC Address or media access control address is a unique ID assigned to network interface cards (NICs). It is also known as a physical or hardware address. It identifies the hardware manufacturer and is used for network communication between devices in a network segment.MAC Address or media access control address is a unique ID assigned to
What information can be determined from a devices MAC address?
If assigned by the manufacturer, a MAC address usually encodes the manufacturer’s registered identification number. It may also be known as an Ethernet hardware address (EHA), hardware address, adapter address, or physical address.
What can a MAC address be used for?
A media access control address (MAC address) is a unique identifier assigned to a network interface controller (NIC) for use as a network address in communications within a network segment. This use is common in most IEEE 802 networking technologies, including Ethernet, Wi-Fi, and Bluetooth.
Can you be tracked by your MAC address?
Across the Internet, no. MAC addresses don’t cross network boundaries. Your phone has a mac address (both its wifi interface and 4g/5g), just like any computer does; and just like any other device, you don’t trace a MAC because that is not how the protocol works.
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 can hackers do with an IP address?
There are thousands of ports for every IP address, and a hacker who has your IP can try all of those ports to brute-force a connection, taking over your phone for example and stealing your information. If a criminal does get access to your device, they could also install malware on it, which could expose your IP.
Is a MAC address sensitive information?
The address is (and needs to be) visible to everyone on the network segment, but because of how network routing works, is not normally visible to anyone else. Unless you take steps to change it regularly, your MAC address uniquely identifies your device.
Are MAC addresses unique?
Each MAC address is unique to the network card installed on a device, but the number of device-identifying bits is limited, which means manufacturers do reuse them. Each manufacturer has about 1.68 million available addresses, so when it burns a device with a MAC address ending in FF-FF-FF, it starts again at 00-00-00.
Can Google see my MAC address?

Is MAC address a physical address?
The physical address is used to identify a device in computer networks. Since MAC addresses are assigned directly by the hardware manufacturer, they are also referred to as hardware addresses. With Microsoft Windows, the MAC address is referred to as the physical address.
Are MAC addresses permanent?
Every network adapter must have a MAC. A MAC is unique and permanent. It’s embedded in each networking adapter by the manufacturer.
What is the difference between a MAC address and an IP address which address can you assign to a computer?

Is WIFI address the same as MAC address?
To improve privacy, your device uses a different MAC address with each Wi-Fi network. To communicate with a Wi-Fi network, a device must identify itself to the network using a unique network address called a Media Access Control (MAC) address.
Is it legal to change your MAC address?

How often does IP address change?
Every 14 days
Every 14 days there is a DHCP lease renewal that takes place that acts kind of like a handshake between the ISP and a household modem. If the connection is still valid the ISP will move on and not disrupt service via provisioning a new IP address.
