# 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.

# 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.
|
||
