我不太懂如何排除dns错误或如何找到dns错误的来源，只能想出这个办法：
请大家在自己的机器上做一个操作：
如果是BSD系统请：
>dig sourceforge.net
或
>host sourceforge.net
「我不确定Linux上查域名用什么命令，请高手指出」
然后把结果发到邮件列表上来，并附上你的dns服务器地址『如果dns服务器地址是
一个cache nameserver请找出真正的dns服务器地址。我们找找看哪些地域不能访问。
如果有高手可以直接找到域名不能解析的原因请出来现身说法，非常感谢。
有人同意我的建议吗？

But there're many root servers, for example f.root-servers.net can be
reached, why slashdot.org can be resovled? Try these two commands:
leo:~# dig www.slashdot.org
; <<>> DiG 9.2.1 <<>> www.slashdot.org
;; global options: printcmd
;; connection timed out; no servers could be reached
leo:~#
leo:~#
leo:~#
leo:~#
leo:~#
leo:~# dig wwwwww.slashdot.org
; <<>> DiG 9.2.1 <<>> wwwwww.slashdot.org
