Free DNS tools built for developers, sysadmins, and website owners across Canada and beyond.
DNSChecker.ca is a free, independent DNS toolset designed to make DNS management easier for everyone — from professional developers and system administrators to small business owners managing their own websites.
DNS is the foundation of the internet, yet it remains poorly understood by many website owners. We built DNSChecker.ca to bridge that gap — providing professional-grade DNS tools that are completely free, require no signup, and are accessible to anyone.
We believe that understanding and managing DNS should not require expensive software or specialist knowledge. Our tools are designed to be simple enough for beginners while powerful enough for professionals.
DNSChecker.ca is proudly Canadian. We operate under Canada's domain extension to serve the Canadian web community — developers, agencies, and businesses across BC, Ontario, Quebec, Alberta, and every province. That said, our tools work globally and are used by people in 100+ countries.
Our DNS propagation checker uses Google's public DNS-over-HTTPS API to perform real-time lookups from a globally distributed network of DNS resolvers. Results are fetched fresh on every query — we don't serve cached or outdated data.
Our IP geolocation tool uses the ipapi.co API, which provides accurate location data based on publicly available GeoIP databases.
We don't require an account, don't track what domains you look up, and don't sell data. See our Privacy Policy for full details.
