Thanks for getting in touch. Although we don't support wildcards, we do support reporting by Subnets via out 'In subnet' operator.
1. Go to Reports | Overview Report (or Activity Report) 2. Click the Filters button next to the Date Pickers (the Filters UI is already displayed when running Activity Reports) 3. Select the filter: Source Address 'In subnet' 192.168.1.0/24 (replace with actual subnet you want to filter on using CIDR notation). 4. Select your Date Range and click Run Report (or Schedule Report).
The final report will be created using only data in the subnet you defined. You can also exclude subnets using the 'Not in subnet' operator, and entering the subnet to exclude in CIDR notation.
