List of Server Names Query for IP

I have a list of approxiamately 300 servers names in an excel spreadsheet that I copied to a test file (one servername per line). I need to run a command or utility that will give me the IP of each server. NSlookup doesnt apear to have a file import function and many of the port scanners only take list of ip to resolve to name. Any ideas?

thanks

If *nix:

#!/bin/bash

touch <output filename>

cat <input filename> | while read line
do
set $line
host $line >> <output filename>
done

Hi Jesper thanks for the reply. I am not a scripter. How do I package the commands you listed? thanks

Jan Bacher

Do you have a linux/solaris/hpux/tru64 operating system? I am not familiar with windows batch commands.

Your other option would be to upload the domain names, I'll run it and upload the results.

No we are all windows and the servers are not public so youwouldnt be able to run the script for me... thanks for the help though

What about something along the lines of (for a batch file):

for /f "%a" in (filename.txt) do nslookup "%a"

Hey Jesper how would you make this statement into a batch? If i save it in a text file and change the exension to .bat and run in a cmd prompt i get an error at the "for" statement
