The most exhaustive list of reliable DNS resolvers.

- resolvers.txt: A simple list of resolver IP addresses, which you can pass directly to your DNS enumeration tool.

- resolvers-extended.txt: All of the resolvers in resolvers.txt with additional information about each server, including the organization it belongs to, its country, and how many times it has been detected as valid. If a resolver is valid enough times, it may earn its place in the next file.

- resolvers-trusted.txt: A list of trusted resolvers from organizations like Cloudflare, Google, etc. We recommend you use this list to re-validate the results you get with the main resolvers.
