我是设置对几个大型Web主机的DNS服务器进行监控的过程.
我的目标是通过跟踪他们对ping的响应来比较他们的DNS服务器响应时间.

在此过程中,我发现Bluehost名称服务器不响应ping.
我试图通过运行Pingdom DNS Check on bluehost.com来获取更多信息,它产生了以下错误：@H_404_5@
Name server ns1.bluehost.com (74.220.195.31) does not answer queries over TCP.@H_404_5@
The name server Failed to answer queries sent over TCP. This is probably due to the name server not correctly set up or due to misconfgured filtering in a firewall. It is a rather common misconception that DNS does not need TCP unless they provide zone transfers – perhaps the name server administrator is not aware that TCP usually is a requirement. @H_404_5@
