I will just make scripts like this:<br>
<br>
<br>
<br>
<br>
for ip in x.x.x.x x.x.x.x x.x.x.x ; do<br>
host $ip<br>
done<br>
<br>
<br>
Works fine.<br>

Should still work. Here's how I'd run it on one of my servers:<br>

If it's not working for you, try just "host ip_address". If that fails, too, you have some weird DNS stuff going on.<br>

What are you using for the list of host names? The code posted<br>
before works fine as long as you're giving it a list correctly.<br>

I want to review out networks<br>
periodically for current dns<br>
records, using the host dns lookup<br>
tool. I would like to use a bash<br>
script and have it look up 30-50<br>
IPs per run. Anyone have a simple<br>
script for this?<br>
