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
| Option | Description | Syntax | Example(s) | |
|---|---|---|---|---|
| 1 | Simple | Enter a fixed IP address. | a.b.c.d | 10.0.10.9 |
| 2 | Hostname | Enter a hostname. PRTG will resolve it to an IP address in your network. | hostname | device-xyz |
| 3 | 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 |
| 4 | Range | Enter an IP address range. | a.b.c.d (see note below) | 10.0.0.1-20 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!
