CustomerGauge allows you to "wildcard" the IP address range. For instance: 


You can use "216.82.0.0/16" for bellow IP address:

216.82.251.234

216.82.251.229

216.82.243.84

216.82.243.88

216.82.243.87

216.82.241.35

216.82.251.232


"216.82.0.0/16" will support "216.82.0.0" to "216.82.255.255".


The wildcard will allow you to reduce the number of entries in IP security lists and not have to update the list for minor changes in the IP address, e.g. 117.120.16.138 to 117.120.16.139. 


This also works for Digital Signage.
