Right now this only looks at the nameserver setting. It is initally made for asynchronous AD DC lookup routines, where we don't need the "search", "domain" and other settings. When we convert general "net", "smbclient" and others to use this, we might either add "domain" handling to this code or look at something like c-ares which already does it.
