Cisco 871 Log file

[mrhooper11]

I recently noticed the following errors in my log file:

DNS Limited Broadcast Query... I have attached a screen shot of the log file.

On my DNS log i am constantly getting createfetch commands. The log file swelled to 2.5 GB in a short time.

Any ideas what might be going on?

Thanks

You can find signature definition here.

This signature fires when multiple UDP packets are 
sent to the limited broadcast address of 255.255.255.255 and a 
destination port of 53.

Cisco IOS routers with "ip domain lookup" enabled may cause this alert to fire.

Thank you for pointing me in the right direction. That search signatures is a great resource.
