How to find all static IP addresses in use

[mabuhay 0]

How can I find all static IP addresses in use on Windows NT server? We have several printers and PCs with static addresses, but they are not in the "Reservations" list, and do not show up in the "Active Leases" because they don't use DHCP. I want to be sure I don't assign the same static IP address to some new wireless units we just got, but, other than trial and error through pinging addresses, I'm not sure how to do it.

Thanks for any help.

Code:

ipconfig /all

Let´s say, you got 1000 computers, then you would youse ipconfig on all 1000. Good luck. when you are so stupid, then don´t say anything

Where did he say anything about 1000 PCs? He just wanted to know...

I couldn't agree more, therefore I will ask you once not to bash other users. A simple batch deployment could ask each machine to pipe the output to a file and then upload those files to a given target if needed.

Easily missed, especially as the first sentence was a little misleading, but there you go

I read a section in the book "Hacking Exposed 2nd".

They mentioned something about "Ping Sweep" which is a part of tools for finger-printing.

 

Whatever your intention is, the pingsweep is a very good tool to see which IP address(es) is (are) alive (being used).

 

Another way is to write a script, based on your subnet masking -- and tries to ping *every* IP address in your calculated subnet.

 

Another method is -- if you happened 2 be the sys-admin of the DHCP server... )

I would have to dig up this Excel spreadsheet that I have that does it. If I find it again, I'll send it to you.
