// 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
// for the scala model only
libraryDependencies += "fr.davit" %% "taxonomy-model" % "<version>"
// for the binary protocol with scodec
libraryDependencies += "fr.davit" %% "taxonomy-scodec" % "<version>"Here is a quick example of a DNS lookup to the 9.9.9.9 DNS server for the davit.fr domain name
