Information you enter into our tools
Subnet calculations are designed to run locally in your browser. IP addresses and CIDR values entered into the calculator are not sent to a calculation server by the tool itself.
Server and analytics data
Like most websites, our hosting provider may process standard technical logs such as IP address, browser type, requested URL, timestamps and security information. If analytics are enabled, we may collect aggregated usage information to understand which pages are useful and improve the site.
Advertising
We may use third-party advertising services, including Google AdSense. Advertising providers may use cookies or similar technologies to serve and measure ads, subject to their own policies and applicable consent requirements.
Cookies
The core subnet calculator does not require an account. Cookies may be used by analytics, security or advertising services if those services are enabled.
Third-party links
Pages may link to external websites. We are not responsible for the privacy practices or content of third-party sites.
