I found one on my network and it was a Q-See Video DVR. I am not sure how it is conveying a mac address past the standard 12Digits in DHCP?
The network card's serial number, usually known as the MAC address.
A device identifier usually refers to a MAC address.
Yes you can track any device by using what is called a a MAC address. Every device on this planet has a mac address that can be tracked.
You can't. The MAC address is a permanant part of the device.
BRIDGE
MAC addresses and IP addresses are two different representations of how to send data to a device by network protocol. A MAC address is the unique identity of a device, used in a network to distinguish one device from another. An IP address is a unique address that shows how traffic should be routed to reach the device.
The destination MAC is before the source one for easier scanning, mostly because it is the destination device that is important as that is the device we are trying to reach.
A host on a network is generally a device with a unique mac address (hardware address, set at the factory) It can be a PC with a network device, a network switch, a printer etc etc hosts can have an IP address mapped to their mac address's
Yes. A mac address is assigned to a device at the factory and cannot be altered. In most cases, it is the IP address that is temporary and often changes.
A Switch looks at the MAC address its a layer 2 device (OSI Model).
yes. thougth the nic is a layer 1 device its mac address is used in datalink layer
That is called the MAC address.
