Does Subnet Calculator run locally?
Most checks run in your browser. When a test needs DNS or public IP data, the page explains that limitation before showing the result.

Which IP pages should I open next?
Start with 192.168.1.1, 192.168.0.1, 192.168.1.254, or the gateway reported by your operating system.
