PRTG Manual: Define IP Ranges

In some setting fields, you can either enter a host name or single IP address, or you can define IP ranges. PRTG follows a common syntax for this. IP ranges are available, for example, for xFlow and Packet Sniffer sensors, and for probes settings.

Note: For the syntax available for PRTG's automatic network discovery, please see Auto-Discovery (IP Selection Method setting).
