正则同时匹配 IPv4和IPV6
要同时匹配IPv4和IPv6，可以使用如下正则表达式：
IPv4:
^(?:(?:25[0-5]|2[0-4]\d|[01]?\d\d?)\.){3}(?:25[0-5]|2[0-4]\d|[01]?\d\d?)$
IPv6:
^(?:(?:(?:[a-fA-F\d]{1,4}):){6}|(?:(?=(?:[a-fA-F\d]{0,4}:){0,5}(?:[a-fA-F\d]{1,4}:|$))(?:(?:25[0-5]|2[0-4]\d|[01]?\d\d?)(?:\.(?:25[0-5]|2[0-4]\d|[01]?\d\d?)){3}|(?:[a-fA-F\d]{1,4}):(?:[a-fA-F\d]{1,4}:){0,4}(?:[a-fA-F\d]{1,4}:){0,2}(?:[a-fA-F\d]{1,4}:){0,2}(?:[a-fA-F\d]{1,4}:){0,2}(?:[a-fA-F\d]{1,4}:){0,2}(?:[a-fA-F\d]{1,4}:){0,2}(?:[a-fA-F\d]{1,4}:|$)))(?:(?:(?:\.[a-fA-F\d]{1,4}){7}|(?=(?:[a-fA-F\d]{0,4}:){0,6}[a-fA-F\d]{1,4}$)(?:[a-fA-F\d]{1,4}(?::[a-fA-F\d]{1,4}){1,6}|(?:(?:25[0-5]|2[0-4]\d|[01]?\d\d?)(?:\.(?:25[0-5]|2[0-4]\d|[01]?\d\d?)){3}))?)$
这两个正则表达式分别用于匹配IPv4和IPv6地址
