Use CIDR notation to designate address exception behavior for an entire subnet.

Syntax:

<IP-address>/<bits-to-consider-as-network-part>

Example:

198.51.100.0/24

--where "/24" denotes the first 3 octets are the network part of this address (198.51.100).

--and, where all hosts beneath the network part will exhibit address exception behavior in WhatsUp Gold.

The previous value is a more compact version of:

198.51.100.0-198.51.100.255
