如何用ssh连接ipv6地址？

我的本地网络很简单。

sudo ifconfig
enp3s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.31.52  netmask 255.255.255.0  broadcast 192.168.31.255
        inet6 fe80::e23f:49ff:fe57:4bd1  prefixlen 64  scopeid 0x20<link>

我想要我的vps拥有ip6地址。

简短回答：

您必须定义公共 IPV6。

长答案：

我假设你的 ISP 给你一个 IP，假设你有2001:0db8:0001:0001::0/64公共 IP（实际上是公共 IPV6 网络）。

现在，尝试

sudo ip -6 addr add 2001:0db8:0001:0001::0022/128 dev enp3s0

在本地主机上。 （替换值和网络接口）

请注意，您将无法从“内部”测试它。 （当我有两个互联网提供商时，我无法保存）。您可以使用互联网上的在线测试 ipv6 工具。

您可以使用以下命令验证您的 ipv6 连接

ping -I enp3s0 ipv6.google.com
