在cmd中ping localhost解析出来的是IPV6的::1,原因是windows有个优先解析列表,当ipv6的优先级高于ipv4时,就会出现这种情况
然后修改优先级:
现在需要设置使::/96、::ffff:0:0/96的优先级高于::/0和::1/128,在命令行中依次设置优先级:
netsh int ipv6 set prefix ::/96 50 0
netsh int ipv6 set prefix ::ffff:0:0/96 40 1
netsh int ipv6 set prefix 2002::/16 35 2
netsh int ipv6 set prefix 2001::/32 30 3
netsh int ipv6 set prefix ::1/128 10 4
netsh int ipv6 set prefix ::/0 5 5
netsh int ipv6 set prefix fc00::/7 3 13
netsh int ipv6 set prefix fec0::/10 1 11
netsh int ipv6 set prefix 3ffe::/16 1 12
再查看优先级:
