感谢楼主的脚本，仅对自用的需求优化了一下，有同样需求的可自取：
1、去除重启机器，仅重启网络
2、pin测试加入自动停止
3、增加设置ipv6优先，并且自动测试是否生效，如果 IPv6 被优先使用，则输出 "IPv6 is preferred."，否则输出 "IPv4 is preferred
Debian_IPv6() {
iName=$(ip add | grep "^2: " | awk -F'[ :]' '{print $3}')
dhclient -6 $iName #临时开启IPv6
echo $iName #人工查看网卡是否正确
sed -i "$ a iface $iName inet6 dhcp" /etc/network/interfaces
ifup $iName #重新启用网络接口，应用新的IPv6配置
sleep 10s #等待10秒，确保IPv6已启用
ip -6 route add default dev $iName #添加IPv6路由，优先使用IPv6连接
ping -c 5 ipv6.google.com #ping 5次，自动停止ping
pkill ping #停止正在执行的ping进程
if [[ $(curl -sS -6 ifconfig.co) =~ ":" ]]; then
echo "IPv6 is preferred."
else
echo "IPv4 is preferred."
fi
}
Ubuntu_IPv6() {
yamlName=$(find /etc/netplan/ -iname "*.yaml")
iName=$(ip add | grep "^2: " | awk -F'[ :]' '{print $3}')
dhclient -6 $iName
MAC=$(ip add | grep "link/ether.*brd" | awk -F' ' '{print $2}')
IPv6=$(ip add | grep "inet6.*global" | awk -F' ' '{print $2}')
if [[ ${#IPv6} -lt 5 ]]; then echo "Can't IPv6"; exit 1; fi
cp $yamlName /root/
cat <<0099 >$yamlName
