I have successfully set up a sensor to monitor our nameservers. (DNS) We use a load balancing appliance and hence our dns servers can be one of 2 addresses. I see you can set up the DNS sensor to email/SMS you if the DNS server IP address changes. This seems to be only one address. Can you specify to "alarm" if the DNS server isn't one of a number of IP numbers, or request an update to your system so this is possible? I can see this as being a very useful sensor for security purposes, especially with the DNS spoofing going on in the Internet.
Thanks in advance
Chris
