How do you find mac address of a remote system and how can we say its the correct onewhat is user changes his mac id?

To get the mac address you will need to use Address Resolution Protocol (ARP). Pretty much this will show an IP address and then give you the MAC address of that computers network card. As for the user changing it. Obviously you cant prevent a user from spoofing a MAC address, but as far as I am aware you cant change it permenently. So I dont think there is very much to worry about there. Also, unless you are dealing with technically minded people, I would doubt that they would even know how to spoof a MAC never mind change it (if its possible that is - which, like I have already said I really dont think it is)

Can you have a dynamic Mac address?

In general, the MAC address is tied to a specific piece of hardware and does not change. It is possible, however, under certain circumstances to change the MAC address. MAC addresses are most often assigned by the manufacturer of a network interface card (NIC) and are stored in its hardware, the card's read-only memory, or some other firmware mechanism. If assigned by the manufacturer, a MAC address usually encodes the manufacturer's registered identification number and may be referred to as the burned-in address. It may also be known as an Ethernet hardware address (EHA), hardware address or physical address. Although intended to be a permanent and globally unique identification, it is possible to change the MAC address on most modern hardware. Changing MAC addresses is necessary in network virtualization. In this case, the MAC address of the actual NIC is hidden from the network and the network only sees the MAC assigned to the virtual NIC - which can be configured, with some finesse, to be dynamic. It can also be used in the process of exploiting security vulnerabilities. This is called MAC spoofing.


What is the difference between a hardware address and IPv4 address?

Hardware address is the MAC address. IPv4 is the IP address. The MAC address is assigned to each network device at the time it's manufactured and does not change. The IP address is manually assigned and can be changed.


Does a microwave oven have a Mac address?

We don't usually see microwave ovens with a MAC address as they just aren't network compatible. They are stand alone devices and don't need to be connected to anything (except power) to work. That means they don't need a MAC address.
