IPv6 Address
|
|
Expression |
(^\d{20}$)|(^((:[a-fA-F0-9]{1,4}){6}|::)ffff:(25[0-5]|2[0-4][0-9]|1[0-9][0-9]|[0-9]{1,2})(\.(25[0-5]|2[0-4][0-9]|1[0-9][0-9]|[0-9]{1,2})){3}$)|(^((:[a-fA-F0-9]{1,4}){6}|::)ffff(:[a-fA-F0-9]{1,4}){2}$)|(^([a-fA-F0-9]{1,4}) (:[a-fA-F0-9]{1,4}){7}$)|(^:(:[a-fA-F0-9]{1,4}(::)?){1,6}$)|(^((::)?[a-fA-F0-9]{1,4}:){1,6}:$)|(^::$)
|
|
Description |
This matches all valid forms of an IPv6 address. Including the compatibility form used to map IPv4 addresses. As well as the base-85 encoded integer form.
It takes care of value range checking on the ipv4 part (components cannot exceed 0-255).
This has been tested quite thoroughly, but considering the complexity and possibilities in the formation of an IPv6 address, matching errors are not guaranteed to be absent.
