MAC Address or Media Access Control Address

MAC address is an unique identifier assigned to every network interface card or network adapters in any network.It is assigned by the manufacture.This is a 12 digit Hexa decimal number.The MAC address is actually the physical address of the network adapter.The unique nature of this ID makes it very helpful in computer forensics.We will discuss about this in detail in other posts.

So now we know what is a MAC address... But how can we find out the MAC address of our network adapter...?

start > run > cmd > type ipconfig/all

This will reveal the MAC address of your network adapter.

When ever a host connects to a network it is assigned with an IP.If we know the IP of the host in the network we can find its MAC address by analyzing the ARP table.We will discuss about the ARP table in another post.

To view the ARP table, type arp -a in the command prompt


TIPS :
For MAC address spoofing,Data traffic spoofing,Sniffing etc. MAC address of the default gateway is very useful.
