About DNS Change

Our Mission

DNS Change was built with a simple goal: give developers, system administrators, and website owners a fast, free, and reliable way to check DNS propagation across the globe.

What We Do

DNS Change is a real-time DNS propagation checker that queries over 30 independent DNS resolvers across six continents. We support A, AAAA, CNAME, MX, NS, TXT, SOA, and PTR records with response times and an interactive world map.

Why DNS Change Exists

DNS propagation has always been frustrating. We built DNS Change to be clean, modern, and fast — giving you answers in seconds with no account required and no rate limits.

Our DNS Infrastructure

Our resolver network includes Google Public DNS, Cloudflare, Quad9, OpenDNS, Comodo Secure DNS, and regional ISP resolvers for comprehensive geographic coverage.

Technology

Built with vanilla JavaScript, parallel DNS queries, and Leaflet.js maps. Designed for desktop, tablet, and mobile.

Privacy First

We don't store lookup history, require accounts, or fingerprint users. See our Privacy Policy.

Open and Free

Completely free. No premium tiers, no feature gates. Sustained through minimal advertising and community support.
