我对 IPv6 世界很陌生。
我正在尝试fc00::a6:32:67:c9:23
从同一网络上的另一台主机 ping 地址,但到目前为止它不起作用(尽管我能够使用 Link-Local 单播地址 ping 设备)。
我的本地主机(ping 的来源)上的网络配置如下所示:
host1$ ip addr
2: wlp6s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
link/ether 10:4a:7d:cd:e6:73 brd ff:ff:ff:ff:ff:ff
inet 192.168.55.61/24 brd 192.168.55.255 scope global dynamic noprefixroute wlp6s0

5: enx000ec6a6aea4: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
link/ether 00:0e:c6:a6:ae:a4 brd ff:ff:ff:ff:ff:ff

valid_lft forever preferred_lft forever
inet6 fe80::2576:c20e:e91d:7677/64 scope link noprefixroute
valid_lft forever preferred_lft forever
本地路由表如下所示:
$ ip -6 route
::1 dev lo proto kernel metric 256 pref medium
2001:db8:100:1ff:ff:ff:ff:ff dev enx000ec6a6aea4 proto static metric 1024 pref medium
fc00::/64 dev enx000ec6a6aea4 proto kernel metric 256 pref medium
fe80::/64 dev wlp6s0 proto kernel metric 1024 pref medium
fe80::/64 dev enx000ec6a6aea4 proto kernel metric 1024 pref medium
default via 2001:db8:100:1ff:ff:ff:ff:ff dev enx000ec6a6aea4 proto static metric 1024 pref medium
目标主机上的界面如下所示:
host2$ ip a
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
link/ether dc:a6:32:67:c9:23 brd ff:ff:ff:ff:ff:ff
inet 192.168.55.187/24 brd 192.168.55.255 scope global dynamic noprefixroute eth0
valid_lft 599sec preferred_lft 524sec
inet6 fc00::a6:32:67:c9:23/64 scope global tentative noprefixroute
valid_lft forever preferred_lft forever
inet6 2001::a6:32:67:c9:23/64 scope global noprefixroute
valid_lft forever preferred_lft forever
inet6 fe80::a790:54e2:224b:f14/64 scope link
valid_lft forever preferred_lft forever
我想知道为什么目标主机上我的 -prefixed IP 地址tentative
旁边有一个?fc00
有人知道吗?这是我的ping问题的原因吗?
