Tom F 487e4636d5 ZoneParser: error on parsing an IPv6 address in an A record (#923)
* ZoneParser: error on parsing an IPv6 address in an A record

And vice versa for IPv4 with AAAA.

The implementation of isIPv6 is inspired by e341bae08d/src/net/ip.go (L678-L681) .

* Fix benchmarks that try to use ::1 as A record.

* Test A/AAAA parsing via NewRR rather than zone parser.

* Document why we distinguish IPv4 vs IPv6 via existence of ":".

Build Status Code Coverage Go Report Card

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.

Users

A not-so-up-to-date-list-that-may-be-actually-current:

Send pull request if you want to be listed here.

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

Building is done with the go tool. If you have setup your GOPATH correctly, 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.
