IPv6IP字符串格式的正則表達(dá)式

1、表達(dá)式全文

/^([\da-fA-F]{1,4}:){6}((25[0-5]|2[0-4]\d|1?\d\d?)\.){3}(25[0-5]|2[0-4]\d|1?\d\d?)$|^([\da-fA-F]{0,4}:):([\da-fA-F]{1,4}:){0,4}((25[0-5]|2[0-4]\d|1?\d\d?)\.){3}(25[0-5]|2[0-4]\d|1?\d\d?)$|^([\da-fA-F]{1,4}:){2}:([\da-fA-F]{1,4}:){0,3}((25[0-5]|2[0-4]\d|1?\d\d?)\.){3}(25[0-5]|2[0-4]\d|1?\d\d?)$|^([\da-fA-F]{1,4}:){3}:([\da-fA-F]{1,4}:){0,2}((25[0-5]|2[0-4]\d|1?\d\d?)\.){3}(25[0-5]|2[0-4]\d|1?\d\d?)$|^([\da-fA-F]{1,4}:){4}:([\da-fA-F]{1,4}:){0,1}((25[0-5]|2[0-4]\d|1?\d\d?)\.){3}(25[0-5]|2[0-4]\d|1?\d\d?)$|^([\da-fA-F]{1,4}:){5}:((25[0-5]|2[0-4]\d|1?\d\d?)\.){3}(25[0-5]|2[0-4]\d|1?\d\d?)$|^([\da-fA-F]{1,4}:){7}[\da-fA-F]{1,4}$|^[\da-fA-F]{0,4}:((:[\da-fA-F]{1,4}){1,6}|:)$|^([\da-fA-F]{1,4}:){2}((:[\da-fA-F]{1,4}){1,5}|:)$|^([\da-fA-F]{1,4}:){3}((:[\da-fA-F]{1,4}){1,4}|:)$|^([\da-fA-F]{1,4}:){4}((:[\da-fA-F]{1,4}){1,3}|:)$|^([\da-fA-F]{1,4}:){5}((:[\da-fA-F]{1,4}){1,2}|:)$|^([\da-fA-F]{1,4}:){6}:([\da-fA-F]{1,4})?$|^([\da-fA-F]{1,4}:){6}:$/ 

2、分段解釋

2.1 IPv6 兼容IPv4規(guī)則

IPv6兼容IPv4的字符串格式是一種特殊的IPv6地址表示方法，用于在IPv6網(wǎng)絡(luò)中表示IPv4地址。這種表示方法使用了IPv4映射地址和6to4地址。
IPv4映射地址用于將IPv4地址嵌入到IPv6地址中。它使用冒號（:）分隔的四個十六進(jìn)制數(shù)字來表示，其中前三個數(shù)字表示網(wǎng)絡(luò)的IPv6前綴，而后一個數(shù)字表示IPv4地址的八位數(shù)。例如，0:0:0:0:0:FFFF:w.x.y.z 或 ::FFFF:w.x.y.z 表示一個IPv4地址 w.x.y.z。

2.1.1 IPv4的正則

IPv4地址位小于等于255的三個數(shù)字用小數(shù)點分割。例如，w.x.y.z 表示一個IPv4地址 w.x.y.z。

/^((25[0-5]|2[0-4]\d|1?\d\d?)\.){3}(25[0-5]|2[0-4]\d|1?\d\d?)$/ 

2.1.2 IPv6兼容IPv4全字符的正則

IPv6兼容IPv4的字符串格式，則是在IPv4串前加上以冒號隔開的6組4位16進(jìn)制字符，并在IPv4前加冒號隔開。例如，F(xiàn)FFF:FFFF:FFFF:FFFF:FFFF:FFFF:w.x.y.z 。

^([\da-fA-F]{1,4}:){6}((25[0-5]|2[0-4]\d|1?\d\d?)\.){3}(25[0-5]|2[0-4]\d|1?\d\d?)$

2.1.3 IPv6兼容IPv4字符帶省略寫法的正則

IPv6格式可以進(jìn)行縮寫，縮寫規(guī)則是兩個冒號之間如果都是0的話可以省略，出現(xiàn)一個雙冒號，但是雙冒號只能出現(xiàn)一個，例如，F(xiàn)FFF::FFFF:FFFF:FFFF:FFFF:ww.x.y.z 或 ::FFFF:w.x.y.z

^([\da-fA-F]{0,4}:):([\da-fA-F]{1,4}:){0,4}((25[0-5]|2[0-4]\d|1?\d\d?)\.){3}(25[0-5]|2[0-4]\d|1?\d\d?)$|
^([\da-fA-F]{1,4}:){2}:([\da-fA-F]{1,4}:){0,3}((25[0-5]|2[0-4]\d|1?\d\d?)\.){3}(25[0-5]|2[0-4]\d|1?\d\d?)$|
^([\da-fA-F]{1,4}:){3}:([\da-fA-F]{1,4}:){0,2}((25[0-5]|2[0-4]\d|1?\d\d?)\.){3}(25[0-5]|2[0-4]\d|1?\d\d?)$|
^([\da-fA-F]{1,4}:){4}:([\da-fA-F]{1,4}:){0,1}((25[0-5]|2[0-4]\d|1?\d\d?)\.){3}(25[0-5]|2[0-4]\d|1?\d\d?)$|
^([\da-fA-F]{1,4}:){5}:((25[0-5]|2[0-4]\d|1?\d\d?)\.){3}(25[0-5]|2[0-4]\d|1?\d\d?)$|

2.2 IPv6字符串格式

IPv6地址由8組由冒號分隔的4位十六進(jìn)制數(shù)字組成，每組數(shù)字范圍在0到ffff之間。例如，F(xiàn)FFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF。
IPv6格式可以進(jìn)行縮寫，縮寫規(guī)則是兩個冒號之間如果都是0的話可以省略，出現(xiàn)一個雙冒號，但是雙冒號只能出現(xiàn)一個，例如，F(xiàn)FFF::FFFF:FFFF:FFFF:FFFF:FFFF:FFFF 或 ::FFFF

2.2.1 IPv6全字符串的正則

IPv6地址由8組由冒號分隔的4位十六進(jìn)制數(shù)字組成，每組數(shù)字范圍在0到ffff之間。例如，F(xiàn)FFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF。

^([\da-fA-F]{1,4}:){7}[\da-fA-F]{1,4}$

2.1.2 IPv6字符帶省略寫法的正則

IPv6格式可以進(jìn)行縮寫，縮寫規(guī)則是兩個冒號之間如果都是0的話可以省略，出現(xiàn)一個雙冒號，但是雙冒號只能出現(xiàn)一個，例如，F(xiàn)FFF::FFFF:FFFF:FFFF:FFFF:FFFF:FFFF 或 ::FFFF文章來源地址http://www.zghlxwxcb.cn/news/detail-845560.html
