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?

The filename is whatever.bat.  You run it by typing 'whatever'.

You need to have the input file in the same directory or specify the full path name to the file.

Modify 'MyFilename.txt' and 'Results.txt' to what you would like.

This should work according to all of the batch scripting that I've read:

@echo off
for /F %a in MyFilename.txt do nslookup %a >> Results.txt

If *nix:


touch <output filename>

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

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
