POE::Component::Client::DNS is a wrapper for non-blocking Net::DNS. It lets other tasks to run while something is waiting for a nameserver to respond, and it lets several DNS queries run in parallel. . DNS client components are not proper objects. Instead of being created, as most objects are, they are "spawned" as separate sessions. To avoid confusion (and hopefully not cause other confusion), they must be spawned with a spawn method, not created anew with a new one.
