Internal IP addresses

It's been a long time since I've used command line. Is there a command to see all internal ip addresses on a network? If I'm wrong about that, can you suggest an alternative?

I'd like to prevent having to go to each computer using ipconfig individually.

Thanks!

 

Do you have a list of the computer names?

If not, then use:

net view /domain:your_domain_name > computers.txt

This will create a file of all the computers on your domain. (if you have a domain).

Then you can write a simple batch file with the "for" statement to call the file computers.txt with the ping command, to get all the ip's.

If you need help, either I or someone else here can write this out for ye.

 

So, the bat file could be something like this:

@echo off
net view /domain:your_domain_name > c:\computers.txt
for /F "eol=; tokens=1" %%i in (computers.txt) do ping %%i >> c:\ping_results.txt
del c:\computers.txt
notepad c:\ping_results.txt
exit

You could even parse the results, with more "for" statements or other commands.

The "for" command is very powerful, and not used all that often. I love the command.

 

Thanks for taking the time to do that for me. I will try to test it out tomorrow or Monday at work.

THANKS!

 

Didn't take that much time, since I was already familiar with it.

Please note, you may need to change it a bit, pending on what windows OS you have at work.

The "for" and the "net" command didn't look that different, from what I was use to, but I tested something close, with my home vista rc1 box, that I'm using right now.

If it doesn't work, please post any errors here.

 

To speed it up a bit, use this line instead:

for /F "eol=; tokens=1" %%i in (computers.txt) do ping -n 1 %%i >> c:\ping_results.txt

Note #143: Pending on how many clients you have, this may take a LOOONG time to run.

Also, if it is a large file, notepad may not be able to handle it, so wordpad or winword may be a better choice.

 

It ran the .bat file, but I'm doing something wrong. Let me give you a little more info. Peer to peer network of six computers, no server. All running Windows XP. Linksys router, Netgear switch. Thanks!

Here's what the ping_results file said:

Okay, sounds like ya may want to manually edit out the \\ makrs in the text file that it creates. sorry.

Maybe this will work:

for /F "eol=; tokens=1 delims=\\" %%i in (computers.txt) do ping %%i >> c:\ping_results.txt

What are the results of the computers.txt file?

 

Better yet, what is the result of this:

net view /domain:your_domain_name
