上面是我在邮件列表的问的
然后如下回复
There are no options, it just works.

pdnsd可以实现

@piaoxueblog 嗯这个我知道
我还需要智能解析的功能（就是不通的域名选择不同的上游dns服务器），这个pdnsd貌似没有
pdnsd与dnsmasq结合起来到能实现 ，若dnsmasq自己就能通过tcp的话更好

你可以换个方式问：例如 I want to disable UDP completely

目测dnsmasq只是把TCP用作UDP的一个fallback

Or I want to always use TCP for some specific domains.. blahblah

unbound请求上游服务器会用tcp，也可以指定单个域名的上游服务器，这里有篇文章可供参考http://www.quakemachinex.com/blog/?p=186
