IPv6 is not enabled by default when creating a new Vultr instance.
Now, let’s see how our Support Engineers enable IPv6 on Vultr instances. IPv6 can be enabled on an existing Vultr instance or a new Vultr instance. Let’s see both cases in detail.

检查系统是否拥有的IPv6地址
打开终端控制台（windows）
ipconfig
输出

Windows系统的格式为ping -6 IPv6的IP%端口，此处的IP和端口使用%隔开的
nginx
1.找到nginx的安装路径
where is nginx
输出
nginx: /usr/sbin/nginx /usr/lib/nginx
/etc/nginx
/usr/share/nginx
/usr/share/man/man8/nginx.8.gz
用./nginx -V 查看已安装的模块，查看是否支持IPV6的模块已安装
nginx -V
输出
如果有--with-ipv6，则表示已安装此模块，否则需要重新编译安装。
3.查看nginx是否监听IPV6地址
sudo netstat -tulpan | grep nginx
输出：
~# sudo netstat -tulpan | grep nginx
