client <-> (port 53) plugin (ephemeral port) <-> nameserver
(client id space) (plugin id space)
the nameserver may be running on a different port or a different
address or both.
the plugin uses it's own id space to talk to the nameserver.
You could even use firewall rules to intercept and forward on.
In this case you shouldn't need to change the query id.
