What is the Subnet Calc tool?
The NetScanner Subnet Calc tool is a free, browser-based diagnostic utility designed for developers and IT professionals. It allows you to securely inspect configurations, verify deployments, and troubleshoot issues in real-time. Unlike older tools, this check runs instantly and fetches live data.
How to use it
Simply enter your target domain name, IP address, or input string into the scanner above and hit Run Analysis. The tool will automatically parse your input, execute the necessary network requests from our secure proxy, and return the formatted results.
Understanding the Results
Our Subnet Calc tool not only provides raw data but also highlights expert recommendations. Look for yellow warning banners—these indicate potential security vulnerabilities or misconfigurations that you should address.
Limitations
Results are cached for a few seconds to prevent abuse. If you recently updated your DNS records or server configuration, please allow time for global DNS propagation before running the check again.
