This service offers a REST API allowing to perform DNS queries over HTTP from multiple locations worldwide.

It can be used to verify and troubleshoot DNS propagation, geo-aware DNS servers, and Anycast DNS deployments.

We currently have 29 available nodes in 10 countries, and are constantly adding more. If you are an Internet Service Provider or a Telecom Operator willing to give us access to your DNS resolvers, please contact us. Thank you.

The API powering this site (RRDA) is open source and can be downloaded here or on GitHub
