Question 1

How to build a simple DNS server with miekg/dns?

Accepted Answer

Start by defining a handler function similar to net/http, use the dns.Server struct to listen on UDP/TCP, and refer to the examples in the separate exdns repository for practical code snippets. The library mimics net/http patterns for server-side programming.

Question 2

Does miekg/dns support DNS over HTTPS (DoH)?

Accepted Answer

No, miekg/dns primarily supports DNS over TLS (DoT) as listed in the features, but not DoH out of the box. You would need to implement HTTP handling separately if DoH is required.

Question 3

Is miekg/dns better than Go's standard net package for DNS?

Accepted Answer

miekg/dns offers full low-level DNS protocol control, DNSSEC, and server capabilities, while Go's net package provides basic resolution. Choose miekg/dns for building DNS tools or servers; use net for simple client queries.

Question 4

How to handle DNSSEC validation with this library?

Accepted Answer

Use the built-in functions for signing and validating, such as dns.NewRR and dns.Verify, with support for algorithms like ECDSA and Ed25519. The README mentions DNSSEC features but detailed implementation requires consulting the godoc or examples.

Question 5

What are the performance benchmarks for miekg/dns?

Accepted Answer

The library is designed for speed with lean code, and version 2 is noted to be 2x faster. However, specific benchmarks aren't provided in the README; you may need to run tests or check community reports for detailed metrics.

Question 6

Is miekg/dns actively maintained?

Accepted Answer

Active development has shifted to version 2 on a different platform (codeberg.org), while this repo receives only specific fixes, as stated in the README. This could affect long-term updates and support.

Question 7

Can I use miekg/dns for building a recursive resolver?

Accepted Answer

Yes, but it requires manual implementation of recursion logic, caching, and error handling, as the library provides the building blocks but not a complete recursive resolver out of the box.
