## Getting taxonomy

```sbt
// DNS with fs2
libraryDependencies += "fr.davit" %% "taxonomy-fs2" % "<version>"
```

If you want to only part of the project with another IO implementation for instance,
you can import the following sub modules

```sbt
// for the scala model only
libraryDependencies += "fr.davit" %% "taxonomy-model"  % "<version>"
// for the binary protocol with scodec
libraryDependencies += "fr.davit" %% "taxonomy-scodec" % "<version>"
```

## Dns

Here is a quick example of a DNS lookup to the `9.9.9.9` DNS server for the `davit.fr` domain name

```scala
import java.net.{Inet4Address, InetAddress, InetSocketAddress}

import cats.effect.*
import cats.effect.unsafe.implicits.*
import fr.davit.taxonomy.model.record.*
import fr.davit.taxonomy.model.*
import fr.davit.taxonomy.scodec.DnsCodec
import fs2.io.net.Network
import munit.CatsEffectSuite
import scodec.Codec

import scala.concurrent.duration.*

given Codec[DnsMessage] = DnsCodec.dnsMessage

val quad9DnsServer = new InetSocketAddress("9.9.9.9", 53)

val question        = DnsQuestion("davit.fr", DnsRecordType.A, unicastResponse = false, DnsRecordClass.Internet)
val query           = DnsMessage.query(id = 1, questions = Seq(question))
val socketResource  = Network[IO].openDatagramSocket()
val response        = socketResource.use(s => Dns.resolve(s, DnsPacket(quad9DnsServer, query))).unsafeRunSync()
```
