Finding IP address to MAC and vice versa on same network (subnet) or different subnet which is reachable by ping

Hi all,

After long time I got a chance to write the blog.

 

This time it is related to networking.

 

Finding out which all the system up on the network

Syntax

cmd> nmap –sP < regex IP >

Example

cmd> nmap –sP 192.168.1.*

 

Finding MAC address of a device which is connected in same network

Syntax

cmd> ping <broadcast address>

cmd> arp –a [ <IP address> ]

 

Example

cmd> ping 192.168.1.255

cmd> arp –a –> Gives all the IP address and MAC address in the same subnet network

cmd> arp –a 192.168.1.25 –> Give the MAC of the specified IP address

 

arp –a : Lists all the IP addresses which are recently got into network with its MAC addresses

 

Finding MAC address of a device which is connected in same network but different subnet

Syntax

nbtstat –A <IP address>

Example

nbtstat –A 192.168.2.45

Create a command shortcut icon in windows to run a command like pinging Google website

Hi,

One of my friend asked me about how we can check whether ping/network is active or not?

He suggested that, if we have a shortcut command icon on desktop to create ping command then it would be easy for any naïve user to check whether ping/network is active or not?

 

Objective:

Creating Ping command shortcut with google.com

 

Procedure:

1. Right click on the desktop
2. Select “New” from the pop-up menu
3. Choose “Shortcut” option
4. Enter “cmd.exe /K ping google.com” as type of location of the item
5. Click on “Next” button
6. Enter “Ping Google” as name for the shortcut
