奇怪的 IP 路由 - ping 不工作

我无法从我的服务器克隆 bitbucket.org 的存储库，也无法使用 ping 访问 bitbucket.org。到目前为止，使用当前配置，一切正常。

以下是我目前发现的情况：

尝试使用https://ping.eu/ping到 bitbucket.org 工作。

$ ping bitbucket.org 
PING bitbucket.org (18.205.93.0) 56(84) bytes of data.
=> timeout

$ ping google.com
=> works

$ ping apple.com
=> timeout

$ traceroute bitbucket.org
traceroute to bitbucket.org (18.205.93.1), 30 hops max, 60 byte packets

这是什么意思？远处的路由器有问题吗？到达 bitbucket.org 是否存在瓶颈？

平别名ICMP 回应请求有时会被管理员阻止。似乎就是这样。您正在编写使用ping.eu/ping它正在运行，但你可能“忘记”提到所引用的站点使用 IPv6 是成功的：

--- PING bitbucket.org(2406:da00:ff00::22c2:513) 56 data bytes --- 64 bytes from 2406:da00:ff00::22c2:513: icmp_seq=1 ttl=47 time=100 ms 64 bytes from 2406:da00:ff00::22c2:513: icmp_seq=2 ttl=47 time=100 ms 64 bytes from 2406:da00:ff00::22c2:513: icmp_seq=3 ttl=47 time=100 ms 64 bytes from 2406:da00:ff00::22c2:513: icmp_seq=4 ttl=47 time=100 ms

如果您强制使用同一站点 ping IPv4，也不会有响应...

您的请求以“ 开头我无法从 bitbucket.org 克隆存储库“我猜您正在使用 http / https 进行通信，并且这项服务似乎正在运行......
