MAC Addresses
The MAC (or Hardware) address is used by devices to communicate on the local network. Hardware addressing is a function of the Data-link layer of the OSI model. MAC address that is usually hard-coded on the network card, this means The MAC address cannot be altered; the MAC address is often stored in flash on the NIC, and thus can be changed with special utilities.MAC address is represented in two formats (either notation is acceptable):
00:43:AB:F2:32::13
0043:ABF2:3213
MAC address is a 48 bit hexadecimal coded address. first 24 bits tell the information about manufacturer and rest 24 bits represent the machine's information.
for example: 00:43:AB stores manufacturer's details and F2:32:13 stores system's detail.
Changing MAC Address:
IP Addressing is a function of the network layer of the OSI model. It helps in routing data packets hop by hop, node by node in the network. IP address is a 32 bit hexadecimal coded address. Few initial bits represent network id, and rest bit represent host address in the network.
for example: ip address 192.168.65.133
sub-net mask: 255.255.255.0
so, network address is 192.168.65.0
and host location in the network is 133th position.
To Avoid wastage of logical addresses in the network sub-netting is done. To understand sub-netting, you will have to learn IP Addressing. Please watch videos shared below to understand IP addressing in detail. I recommend you to watch these videos, if you are interested in designing and managing networks.
IP Addressing Scheme:
IP Sub-netting And Addressing:
To view all network addresses of your machine:
start--> run---> type "cmd" then enter-----> type command "ipconfig /all".

Changing MAC Address:
- open Network sharing center----> change adapter setting----> choose connection type (LAN or Wireless LAN)
- go to properties---> check connection controller (optional) ---> configure -----> Advance
- Now click on the Network Address, you will see that it is selected as "not present", select "value" and enter some value of MAC address.
- Your MAC address has been changed for a while. Once you turn off your machine the value will be set to default.
- to change value permanently, you will have to change value from "registry", it has been discouraged to change value from the registry if you don't have sound knowledge of registry, it may crash your system.
