About isrange.com

isrange.com provides practical browser tools across IP and network information, text and document utilities, date and time, calculations, conversions, and developer workflows. Tools are designed to give a direct result and explain important assumptions where they matter.

Many tools run entirely in the browser. Public IP connection details are different: they require network requests to determine or enrich address information. See our Privacy Policy for details.

Calculators and reference pages are educational tools, not professional advice. Financial estimates simplify individual circumstances, and BMI is a screening measure rather than a diagnosis. Check official sources and a qualified professional when a decision has material health, tax, or financial consequences.

For 2026 federal income-tax estimates, we use the IRS's published inflation adjustments and employment-tax guidance. BMI content follows the CDC's explanation of BMI's use and limits. Tax-rate and geolocation data can change or vary by locality, provider, or network configuration.

We do not require accounts. The site uses a local theme preference, advertising technology where shown, and limited first-party performance metrics without persistent identifiers. Performance collection respects Do Not Track and Global Privacy Control signals.

Read the Privacy Policy for current details about IP providers, advertising, and anonymous performance measurement.
