6# Alternative (more granular) approach to a DNS library
7
8> Less is more.
9
10Complete and usable DNS library. All widely used Resource Records are supported, including the
11DNSSEC types. It follows a lean and mean philosophy. If there is stuff you should know as a DNS
12programmer there isn't a convenience function for it. Server side and client side programming is
13supported, i.e. you can build servers and resolvers with it.
14
15We try to keep the "master" branch as sane as possible and at the bleeding edge of standards,
16avoiding breaking changes wherever reasonable. We support the last two versions of Go.
17
18# Goals
19
20* KISS;
21* Fast;
22* Small API. If it's easy to code in Go, don't make a function for it.

74# Features
75
76* UDP/TCP queries, IPv4 and IPv6;
77* RFC 1035 zone file parsing ($INCLUDE, $ORIGIN, $TTL and $GENERATE (for all record types) are supported;
78* Fast:
79 * Reply speed around ~ 80K qps (faster hardware results in more qps);
80 * Parsing RRs ~ 100K RR/s, that's 5M records in about 50 seconds;
81* Server side programming (mimicking the net/http package);
82* Client side programming;
83* DNSSEC: signing, validating and key generation for DSA, RSA, ECDSA and Ed25519;
84* EDNS0, NSID, Cookies;
85* AXFR/IXFR;
86* TSIG, SIG(0);
87* DNS over TLS: optional encrypted connection between client and server;
88* DNS name compression;
89* Depends only on the standard library.

91Have fun!

95# Building
96
97Building is done with the `go` tool. If you have setup your GOPATH correctly, the following should
98work:
99
100 go get github.com/miekg/dns
101 go build github.com/miekg/dns
102
103## Examples
104
105A short "how to use the API" is at the beginning of doc.go (this also will show
106when you call `godoc github.com/miekg/dns`).
107
108Example programs can be found in the `github.com/miekg/exdns` repository.
