How to know the IP addresses of other computers on same network..?

Method #1

 

The easiest way is to access the administrator page of you router. It will have information regarding all the devices connected to your network, including their ip addresses.

 

Method #2

If you know the name of the computer you can ping that system and the ping request will return you the ip address of that system.

 

Method #3

In this method we will again use the ping command. First of all, we will be needing our ip address and subnet mask, which can be easily found out by using the "ipconfig" and "ipconfig /all" commands (without " "). 

After knowing your ip and subnet align them. let's assume your ip is 192.168.1.56 and your subnet is 255.255.255.0. Align them,

192.168.1.56

255.255.255.0

Next, replace the 0 in subnet with 255 at the same relative position in your ip.

192.168.1.56 -- 192.168.1.255

Now, ping this new ip address, and all the sysytems capable of responding to ping requests will respond with their ip addresses.

There are other methods available like using tools like wireshark, namp, etc.

Stay tuned for tutorials on these tools.
