第一步，通过命令 ip addr 列出网络接口的名称

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
    link/ether 00:00:5e:00:53:3a brd ff:ff:ff:ff:ff:ff
3: eth1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
    link/ether 00:00:5e:00:53:3b brd ff:ff:ff:ff:ff:ff

第二步：配置上面我们看到的eth0这个接口为ipv6地址：

vi /etc/network/interfaces ，添加：

 iface eth0 inet6 static
        address 2001:db8:100:15a::1
        netmask 64
        dns-nameservers 2001:41d0:3:163::1
        post-up sleep 5; /sbin/ip -family inet6 route add 2001:db8:100:1ff:ff:ff:ff:ff dev eth0
        post-up sleep 5; /sbin/ip -family inet6 route add default via 2001:db8:100:1ff:ff:ff:ff:ff
        pre-down /sbin/ip -family inet6 route del default via 2001:db8:100:1ff:ff:ff:ff:ff
        pre-down /sbin/ip -family inet6 route del 2001:db8:100:1ff:ff:ff:ff:ff dev eth0

第三步：启用网络接口eth0，并且重启网络服务。

ip link set eth0 up
systemctl restart networking

这样基本可以出去了，ping一个ipv6 的地址：
ping6 2606:2800:220:1:248:1893:25c8:1946

IPv6网址建好后，如果自己本机是IPv4的网络，想要测试纯IPv6网址的内容，可以通过 https://ipv6proxy.cn 来进行测试。
