Hickory DNS is a modern, Rust-based DNS client, server, and resolver designed with a focus on safety, security, and performance.
It provides a comprehensive suite of tools for DNS operations, catering to developers and administrators seeking reliable DNS solutions. Below is an overview of its key components and functionalities.
Hickory DNS is structured into multiple crates, each offering specialized functionality:
The Hickory DNS server supports both IPv4 and IPv6 over UDP and TCP. While it is still under development, it offers features like zone file parsing, dynamic updates, and zone signing with DNSSEC.
The server also supports modern protocols like DNS-over-TLS (DoT) and DNS-over-HTTPS (DoH), ensuring secure communication.
The client library allows interaction with DNS servers for operations such as querying records, validating DNSSEC, and performing atomic updates. Unique features include:
create).append).The resolver is a native Rust implementation that supports common query patterns and system configurations on Unix and Windows platforms.
It can handle CNAME chains and SRV record lookups while supporting DoT/DoH for secure query resolution.
Hickory DNS emphasizes security by leveraging Rust’s safety guarantees. It implements numerous RFCs for secure operations, including DNSSEC (RFC 4035) and encrypted transport protocols like DoT (RFC 7858) and DoH.
Hickory DNS aims to deliver:
Hickory DNS is a robust solution for managing DNS infrastructure with cutting-edge security protocols and high configurability.
While still under development, its modular design makes it a promising tool for modern networking needs.
