Tracing route to www.163.com [202.108.36.172]
over a maximum of 30 hops:

1 * * * Request timed out.
2 * * * Request timed out.
3 * * * Request timed out.
4 * * * Request timed out.
5 * * * Request timed out.
后面的都一样
谁能解释一下怎么变成REQUEST TIMED OUT了啊？正常吗？

1.可能主机停机
2.可能主机对ping不相应

你自己的网络环境中是否有防火墙？如果有，这个应该是正确的
