Overview

hickory-net provides network protocol implementations for DNS message transport. This is a support library used by the other higher-level Hickory DNS crates.

For higher-level interfaces, refer to the hickory-server and hickory-resolver library crates instead.

Cryptography provider

Features requiring cryptography require selecting a specific cryptography provider. See the project README for more information.

Protocol support

The following DNS protocols are optionally supported:

• DNS over TLS (DoT)
• DNS over HTTP/2 (DoH)
• DNS over QUIC (DoQ)
• DNS over HTTP/3 (DoH3)

In order to use these optional protocols you must enable a cargo feature corresponding to your desired cryptography provider:

• DoT: tls-aws-lc-rs or tls-ring.
• DoH: https-aws-lc-rs or https-ring
• DoQ: quic-aws-lc-rs or quic-ring
• DoH3: h3-aws-lc-rs or h3-ring

DNSSEC

In order to use DNSSEC you must enable a cargo feature corresponding to your desired cryptography provider:

• dnssec-aws-lc-rs
• dnssec-ring

Other crate features

• tokio - support for the Tokio async runtime.
• serde - enable serde serialization support.
• mdns (experimental) - enable experimental mDNS support.
