hickory-server 0.26.2

hickory-server is a library for integrating safe and secure DNS servers into an async Tokio application. It supports a variety of protocol features (DNSSEC, TSIG, SIG(0), DoT, DoQ, DoH). Servers can be operated in an authoritative role, or as a forwarding resolver, stub resolver, or a recursive resolver (experimental).
