IPV6 ping，pinged地址与wireshark捕获的地址不同。

Question

我正在尝试平一个ECU，PC和ECU都有静态的IPV6地址。问题是目标地址与Wireshark捕获的地址不同。

子网: 64

ping命令

$ ping -6 fd53:7cb8:383:eb03:0:0:0:100

Pinging fd53:7cb8:383:eb03::100 with 32 bytes of data:
Destination host unreachable.
Destination host unreachable.
Destination host unreachable.
Destination host unreachable.

您看到的是邻居发现协议，它在IPv6中取代了ARP。您可以看到数据是ICMP，目标地址是请求的节点地址。你可以在这个来自思科的页面上读到更多关于它的信息。
