What webserver uses akka akka-http and how can I get the version of it?

I'm using akka and akka-http 2.4.2 and I'm trying ti understand the internal components of them.

What does akka and akka-http use to start a rest web-service?
It uses an embebedd webservice? (like Jetty?)
How do I get the version of it?

The code I run to start my rest web-service is:

implicit val actorSystem = ActorSystem("system")
implicit val actorMaterializer = ActorMaterializer()

val route: Route = {
      blablabla ...
}

val bind = Http().bindAndHandle(route, "0.0.0.0", 8080)

Thanks.
