Which syntax can I use to define IP ranges in the PRTG probe and flow sensor settings?



In the probe settings, in the Allow IPs/Deny IPs fields, I would like to add an IP range instead of single IP addresses. How can I do this?

In PRTG's probe settings as well as for NetFlow and packet sniffer definitions, you can use a special syntax to define IPs by hostname, hostmask, or ranges.

Defining IP Addresses—Available Options

1SimpleEnter a fixed IP address.a.b.c.d10.0.10.9
2HostnameEnter a hostname. PRTG will resolve it to an IP address in your network.hostnamedevice-xyz
3HostmaskEnter 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.h10.0.0.0/255
4RangeEnter an IP address range.a.b.c.d
(see note below) or 10.*.0.* or 10.0.0-50.*

Note: When using ranges, replace each of a, b, c, d by:
* (asterisk) = any value; corresponds to 0-255, or
x-y = any range between 0 and 255

Note: This syntax is not available for PRTG's auto-discovery function!
