Quickly Find Used IP Addresses

Posted on January 8, 2009 by Daniel Petri in Networking with

Instead of manually pinging all IP addresses on your LAN you can use this nice command:

Open Command Prompt and type:

The “-n 1” is for only 1 ping packet to be sent to each computer.

Change 192.168.0 to match you own Network ID.

This will ping all IP addresses on the network segment and create a text file called IPADDRESSES.TXT in C:\, where it will list only the IP addresses that gave a reply.


You can also add a -a to the PING command to resolve all the responding IP addresses to HOST names, but doing so will cause the script to take a considerable time to finish:

You can, of course, modify this script and make it suit your own desire.

I’d love to hear about any other ideas you may have .
