netsh int ipv6 set prefixpolicy ::1/128 50 0
echo. ::1/128是本地网关localhost的解析地址，通常获得默认常规“0”优先。
netsh int ipv6 set prefixpolicy ::/0 40 1
echo. ::/0是本地localhost默认的IPV6解析地址，通常获得第40 1 级优先。
netsh int ipv6 set prefixpolicy 2002::/16 30 1
echo. 2002::/16是IPv6到IPV4的接口，通常获得30 1类优先。
netsh int ipv6 set prefixpolicy ::/96 20 3
echo. ::/96 是IPv4的兼容性接口，通常获得20 3级优先。
netsh int ipv6 set prefixpolicy ::ffff:0:0/96 10 4
echo. ::ffff:0:0/96 是IPv4的兼容性接口长地址，通常获得10 4级优先。
netsh int ipv6 set prefixpolicy 2001::/32 5 1
echo. 2001::/32 是IPv6的teredo隧道解析，通常获得5 1级优先。这里我们把它设置为第1位（1）级优先。
