How to use arp -a

What is ARP?
ARP stand for Address Resolution Protocol and it is use to resolve IP address to physical network card address which we called it MAC(Media Access Control) address.
This ARP protocol is operate below Network Layer as a part of OSI Network and OSI Data Link Layer.

Where to get MAC address detail?
Every Network cards have a unique 48 bits address written as six hexadecimal pairs like: 00-21-e7-b1-c0-d0. We still haven see any same MAC address being produce for all the network address devices cause MAC address MUST be unique. To get our network card mac-address is pretty simple in windows based OS.

1. Open up Command Prompt
2. type ipconfig /all
3. Ethernet adapter Local Area Connection:
   
   Connection-specific DNS Suffix . :
   Description . . . . . . . . . . . : Realtek RTL8139 Family PCI Fast Ethe
   rnet NIC
   Physical Address. . . . . . . . . : 00-21-e7-b1-c0-d0
   Dhcp Enabled. . . . . . . . . . . : No
   IP Address. . . . . . . . . . . . : 192.168.1.10
   Subnet Mask . . . . . . . . . . . : 255.255.255.0
   Default Gateway . . . . . . . . . : 192.168.1.1
   DNS Servers . . . . . . . . . . . : 202.188.0.133
   202.188.1.5
4. Physical Address is the PC network card MAC address

IP address & Mac address
if a packet location is on the same local area network then IP address will resolve into Mac-addressm otherwise, IP address will resolve into router Mac-address.

1. Open command prompt and ping to 1 of the IP address within same Local Area Network.
2. type in arp -a
3. Example result shown as below
4. C:\Documents and Settings\Administrator>arp -a
   
   Interface: 192.168.1.10 --- 0x2
   Internet Address Physical Address Type
   192.168.1.1 00-0b-2b-e7-b0-1e dynamic
   192.168.1.2 00-1b-2a-2c-bd-eD dynamic

Inorder to do this, the pc must be ping able and only you will be able to get some info about the Mac-address from the remote pc.
