Network groups

The Network Groups section of the Dashboard is used to search for and manage the network groups that StifleR supports.

A network group in StifleR contains one or more networks. For example, this might represent a group of well-connected subnets.

Network groups list

The Network groups list will display all of the network groups. To view the networks assigned to the location, select the arrow next to the Name.

This will display the Networks associated with the location. You can drill down further to display the assigned Networks or select the Edit icon to modify the Network.

If interested in editing a network group, see the Templates page for more information about available settings.

Supernetting

Supernetting allows StifleR to define and manage networks at a higher level by using aggregated network ranges instead of individual subnets. Rather than specifying each subnet separately, administrators can define a single supernet using CIDR or subnet mask notation, and StifleR will automatically apply that definition to all networks that fall within the specified range.

With supernetting, network definitions can be entered using a combined IP address and mask (for example, 10.10.0.0/16 or 192.168.0.0/255.255.0.0), simplifying configuration and reducing administrative overhead. Any subnet that exists within the defined supernet is automatically matched and handled according to the network group configuration.

This capability is particularly useful when skipping networks or grouping large address spaces. For example, defining a supernet such as 192.168.0.0/16 ensures that all 192.168.x.x networks are covered without requiring each subnet to be listed individually. When a client reports in from a subnet within the supernet range, StifleR dynamically generates the corresponding subnet under the network group and applies the appropriate rules.

Supernetting works consistently across both VPN and non-VPN scenarios, enabling flexible and scalable network grouping while maintaining accurate network detection and control.
