traceroute 疑问，有些地方看不懂，求指导

DO 的新加坡节点，本机 ISP 是山西电信

mtr 结果如下，发现到新加坡的 ping 有 437ms

第一个疑问是为什么有的后一跳的平均值比前一跳都小？

第二个是“ ix-xe-10-2-6-0.tcore2.LVW-Los-Angeles.as6453.net (64.86.252.157)”的 ip 查了归属是印度，好像也没绕美国，如何分析为啥 ping 这么高？大概查了下中国到新加坡 ping 应该也就 100-200ms 左右

谢谢各位 dalao

PS：有啥traceroute + ip location + visualization集成的好工具吗

某度查出来的ip归属竟然是印度
