太简单了?
我想到的只有DNS出错，还有别的可能吗?

发帖数: 1950 | 5 被BS了。这题也是我从别的版上copy过来的。我的理解是client ping一个server,但是
client端看到的ping的结果显示的是另一个server的地址。问可能原因有哪些及如何改
进。

发帖数: 1055 | 6 I can think of couple of scenarios that can cause this:
1) there is a one way NAT device between you and server which translated
ping packet's destination IP to a different IP, when sending echo reply back
, server simply reverses source/destination IP, when echo reply bypasses NAT
, client will receive a different IP from echo request is sent to --- same
argument applies to situation that if there is a device doing source NAT to
echo replies.
2)Just for the sake of argument only, if you are pin |
