A DNS library for Rust – Asynchronous Stub Resolver

This crate provides a modern stub resolver using Tokio.

Please note that this crate will be merged as a module into the domain crate very soon.

Features

Eventually, the stub resolver will provide the following functionality:

• asynchronous stub resolver based on Tokio 0.1

  • unencrypted connections via UDP and TCP,

  • encrypted connections via DNS-over-TLS,

  • encrypted connections via DNS-over-HTTP,

• rich set of queries:

  • querying for raw DNS records,

  • querying for IPv4 and IPv6 addresses,

    • priority according to ‘happy eyeballs,’

  • querying for host names associated with IPv4 and IPv6 addresses,

  • querying for mail servers,

    • pure MX records,

    • IPv4 and IPv6 addresses of the mail server,

    • TLSA, SPF, DKIM, DMARC records,

  • querying for servers via SRV records,

    • pure SRV records,

    • IPv4 and IPv6 addresses of the servers,

    • TLSA records of the servers,
