Re: 關於小弟學校 routing 的小問題

$ traceroute venus.au.edu.tw
traceroute to venus.au.edu.tw (192.192.120.3), 30 hops max, 40 byte packets
 1  tyc-gateway.tyc.edu.tw (192.192.227.14)  0.512 ms  0.371 ms  0.363 ms
 2  192.83.175.112 (192.83.175.112)  1.166 ms  1.125 ms  1.11 ms
 3  192.192.12.172 (192.192.12.172)  1.994 ms  2.009 ms  2.017 ms

 6  venus.au.edu.tw (192.192.120.3)  3.129 ms  2.566 ms  2.7 ms

好像也只是 192.192.12.172 router 常要靠 HINET router re-direction 更正
traceroute 而已, 倒不影響速度.
