UDP上的stream量太多，怀疑绑定未命中configuration

一个服务器在UDP端口上产生超过600GB的每月stream量（而http小于1GB），所以我运行了tcpdump命令，看到很多（超过10 /秒左右）的快速dns相关命令/stream量，如下所示：

• 我不认识域像avo.net.domain / postgirl / postlady，只是“leaseweb.net”，leaseweb是我的托pipe服务提供商。
• 服务器IP是82.192.75.xxx（如上所示）。

我承载了超​​过200个域名，但我怀疑有些外部用户/服务器正在查询或攻击导致所有UDP通信的DNS服务。

我想我错过了configurationnamed.conf通过设置错误的查询或recursion值。 服务器的目的是在这台服务器上托pipe大约200个域名，它不是一个专用的DNS，也不会连接到其他外部服务器或服务。

我应该改变这个named.conf？ 我应该用“localhosts”还是“localnets”代替“any”？ 谢谢。

• 在centos 6.3 64位的DNS和名称服务器没有被ping出来
• 路线53 – IP：PORT
• SSL集成所需的域更改
• bind9的DNS代理
• 如何通过命令行向用户授予Route 53托pipe域的权限？
