domain – A DNS library for Rust

Current Documentation

A library for interacting with the Domain Name System. The crate contains an ever-growing set of building blocks for including DNS functionality in applications.

Currently, these blocks include:

  • basic data structures and functionality for creating and parsing DNS data and messages,
  • support for signing and verifying messages using the TSIG mechanism,
  • experimental support for reading data from DNS master files (also known as zone files),
  • experimental and as yet incomplete support for DNSSEC signing and validation,
  • a simple Tokio-based stub resolver.

What’s Next?

We have collected our plans for the next steps in development of these crates in the Development Roadmap.

For ideas that would benefit from some user feedback, we are creating issues with the discuss label.

If you have ideas, requests, or proposals, don’t hesitate to open issues.


If you have comments, proposed changes, or would like to contribute, please open an issue.
