Alternative (more granular) approach to a DNS library

Less is more.

Complete and usable DNS library. All Resource Records are supported, including the DNSSEC types. It follows a lean and mean philosophy. If there is stuff you should know as a DNS programmer there isn't a convenience function for it. Server side and client side programming is supported, i.e. you can build servers and resolvers with it.

We try to keep the "master" branch as sane as possible and at the bleeding edge of standards, avoiding breaking changes wherever reasonable. We support the last two versions of Go.

Goals

KISS;
Fast;
Small API. If it's easy to code in Go, don't make a function for it.

Features

UDP/TCP queries, IPv4 and IPv6
RFC 1035 zone file parsing ($INCLUDE, $ORIGIN, $TTL and $GENERATE (for all record types) are supported
Fast
Server side programming (mimicking the net/http package)
Client side programming
DNSSEC: signing, validating and key generation for DSA, RSA, ECDSA and Ed25519
EDNS0, NSID, Cookies
AXFR/IXFR
TSIG, SIG(0)
DNS over TLS (DoT): encrypted connection between client and server over TCP
DNS name compression

Have fun!

Building

This library uses Go modules and uses semantic versioning. Building is done with the go tool, so the following should work:

go get github.com/miekg/dns
go build github.com/miekg/dns

Examples

A short "how to use the API" is at the beginning of doc.go (this also will show when you call godoc github.com/miekg/dns).

Example programs can be found in the github.com/miekg/exdns repository.
