网络配置文件 /etc/network/interfaces的典型IPv6配置

# The primary network interface
auto eth0
iface eth0 inet static
address 15.12.178.81
netmask 255.255.255.0
gateway 15.12.178.1

iface eth0 inet6 static
	accept_ra 0
	address 2a04:ac0d:101:84e::
	netmask 64
	gateway 2a04:ac0d:0101:0000:0000:0000:0000:0001
post-up /sbin/ip -r route add 2a04:ac0d:0101:0000:0000:0000:0000:0001 dev eth0
post-up /sbin/ip -r route add default via 2a04:ac0d:0101:0000:0000:0000:0000:0001

# OVZ Debian 9
iface venet0 inet6 static
	address ::2
	netmask 128
	up ip -6 r a default dev venet0
	up ip addr add 210b:5100:60:370f:d3::5cb4/80 dev venet0

参数示意

1、 eth0为网卡 名称

2、 static静态地址

3、address为IP地址

4、netmask掩码

5、gateway网关

6、ip命令增加路由
