How to Create Devices and Targets

How It Works

A DNSBL task polls major domain name service (DNS) Blacklist (DNSBL) databases for an IP or a hostname you specify. If the IP or hostname is found in one of the DNSBL databases, an error will be flagged.

Creating a Target


Enter the server address to be monitored. This could be the URL or the IP address.

Time Validation Threshold (in seconds)

Enter the number of seconds the system should wait for a response from the target resource before returning an error. If this is left blank the default timeout is 120 seconds.
