<%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. These are available, for example, for xFlow and Packet Sniffer sensors and for probe connection settings. PRTG follows a common syntax for IP ranges.

For the supported syntax of the automatic network discovery functionality in PRTG, see section Auto-Discovery (IP Selection Method).

Available Options

Option	Description	Syntax	Examples
Simple	Enter a fixed IP address.	a.b.c.d	10.0.10.9
Hostname	Enter a hostname. PRTG resolves 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. Valid hostmasks are /0 - /32 for IPv4 and /0 - /128 for IPv6.	a.b.c.d/h or a.b.c.d/e.f.g.h	10.0.0.0/24
Range	Enter an IP address range. Replace each of a, b, c, d with 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.*
