Ping 出现: TTL expired in transit. 今天发现电信送的一条固定IP地址出现问题,查确认属于是他们私自更改了我们的IP地址.电话通知电信大客经理...在下午接通知,已经改好! 我觉得还是自已测试一下,不能太相信别人的话,因此我通知他们稍等下.
1、我先PING了一下IP地址,结果发现:
C:/Documents and Settings/xm_dengwh>ping 218.xxx.xxx.xxx (这里是我们的IP地址)
Pinging 218.xx.xx.xx with 32 bytes of data: ,~FyC_%*

需要注意的是: 我的IP地址:218.xxx.xxx.xxx和218.85.151.173不同.
不是正常的TTL返回时间,从提示来看应该是TTL耗尽了,为什么TTL会耗尽呢?难道是路由器配置错误,形成环路了使数据包不停的在两个路由器之间传送,使TTL耗尽?为了证实我的猜想,我觉定使用tracert看一下所经过的路由器情况. C:/Documents and Settings/xm_dengwh>tracert 218.85.xx.xx
