1.没有IPV6的可以工单免费申请/64.
2.在 https://manage.hosthatch.com 后台管理NETWORK处找到IPV6添加子网subnet
3.SSH运行以下命令：

nano /etc/network/interfaces
auto eth0
iface eth0 inet static
   address 你的IPV4地址
   gateway 你的IPV4网关
   netmask 255.255.255.0
   dns-nameservers 1.1.1.1 8.8.8.8
   up ip addr add 您的IPV6地址/64 dev eth0
   up ip -6 route add 你的IPV6网关 dev eth0
   up ip -6 route add default via 你的IPV6网关

4.完成后可以PING一下GOOGLE的ipv6。

ping6 ipv6.google.com

显示如下：
