TTL 变化，可能路径在不断变吧。现在的因特网，不像二三十年前那么简单。另外，路径变的时候 TTL 也可能不发生 “动态变化”。

可能是最奇怪的tracert 结果了，不知道什么原因，成都ADSL，特别提示，我用了无线局域网，ADSL是无线路由器上直接拨号的。

xdsnet

后来发现好的和我类似的情况，tracert 结果了，大家分析一下原因啊。

我多次 traceroute 过去，没发现从哪个路由开始变化，可能他们内部搞啥了。而且，从铁通ping过去的时候，ttl没跳。还有，从英国traceroute过去，包路由到美国再转到中国，都跑了20多个路由了，ttl还是240多，比我从铁通过去的ttl还多一些。。。

路径变的时候 TTL 也可能不发生 “动态变化”。

我曾 traceroute 到美国，第一次经过包括目标地址在内一共 25 跳，然后再试一遍，就成 23 跳了。后来仔细看了一下才明白，前一次数据包在大陆出口的地方打了一个旋，两次经过同一个地址，然后才出去。
