就算不是攻击，也该是什么木马、病毒引起的吧，反正对方是不承认。
这只是一小段，一秒钟差不多有400多个请求，而且不是少数人，我们的DNS
这样搞下去撑不住呵，有什么病毒和木马会引起客户端这个样子，哪位有经验，给提个醒，这样我们也好防范，或提醒用户去做什么针对的操作。谢谢

有些跑题了，我再说一下，这个ping.nnselect.com大家可以在网上搜一下，这个网页是不存在，在google中你会发现，许多大学什么之间架的proxy的流量排名中，ping.nnselect.com是排在很前面的。。。。所以我很费解。如果是个病毒，又这么广，应该能查到相关信息的。
另外大家可以看一下新浪首页的原码中有这一段

而且许多大网站的首页也有这个东东，我现在主要担心不是病毒，而是正常的什么行为触发的，那我这边封IP就理由不充分了
