<%NUMBERING1%>.<%NUMBERING2%>.<%NUMBERING3%> 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 supported syntax of the automatic network discovery functionality in PRTG, please see section Auto-Discovery (IP Selection Method setting).

Available Options

Option	Description	Syntax	Example(s)
Simple	Enter a fixed IP address.	a.b.c.d	10.0.10.9
Hostname	Enter a hostname. PRTG will resolve it to an IP address in your network.	hostname	device-xyz
Hostmask	Enter a hostmask. A hostmask defines the relevant bits of the IP address.	a.b.c.d/h or a.b.c.d/e.f.g.h	10.0.0.0/255
Range	Enter an IP address range. Replace each of a, b, c, d by either * (asterisk) for any value; corresponds to 0-255 —or— x-y for any range between 0 and 255.	a.b.c.d	10.0.0.1-20 or 10..0. or 10.0.0-50.*
