All variants of trailing zeroes are not supported.
e.g. 1::, 1:1:: etc, pp.

Doesn't work for :

etc.
or

This works strictly for IPv6 addresses.
I added a direct test for ipv4 preceding this.
To get this to work with Java, you need to escape the backslash '\' as '\\' So in the regex: {0,2})\.){3} becomes: {0,2})\\.){3}
Also, I added: 0-9A-Fa-f to the [0-9A-F] ranges so I didn't have to convert to uppercase first.

Do any of these work with the Pattern class in Java which deals with regualr expressions. I can't seem to get any working.

Damn... ignore those.
Based on the assumptions in my first comment, the following works for IPv6 addresses (excluding mixed environment):
(([1-9a-fA-F][\da-fA-F]{1,3}|[\da-fA-F][1-9a-fA-F][\da-fA-F]{0,2}|[\da-fA-F]{0,2}[1-9a-fA-F][\da-fA-F]|[\da-fA-F]{0,3}[1-9a-fA-F]):(([\da-fA-F]{1,4}:){6}|([\da-fA-F]{1,4}:){4}:|(([\da-fA-F]{1,4}:){3}:([\da-fA-F]{1,4}:)?)|([\da-fA-F]{1,4}:){2}:([\da-fA-F]{1,4}:){0,2}|([\da-fA-F]{1,4}:):([\da-fA-F]{1,4}:){0,3}|:([\da-fA-F]{1,4}:){0,4})([1-9a-fA-F][\da-fA-F]{1,3}|[\da-fA-F][1-9a-fA-F][\da-fA-F]{0,2}|[\da-fA-F]{0,2}[1-9a-fA-F][\da-fA-F]|[\da-fA-F]{0,3}[1-9a-fA-F]))
and the following works for mixed environment only:
((((0{1,4}:){5}(0{1,4}|[fF]{4}):)|(::([fF]{4}:)?))?((25[0-4]|2[0-4]\d|1\d{2}|[1-9]\d?)(\.(25[0-4]|2[0-4]\d|1\d{2}|([1-9]?\d))){2}(\.(25[0-4]|2[0-4]\d|1\d{2}|[1-9]\d?))))
But combine the in the form (<first>|<second>) and all of a sudden you can enter additional characters as well as the IPv4 address.
Any ideas?

Title: Leading and trailing zeros in IPv6 or mixed environment domain-literals for email addressing

Comment:
I'm looking at this from the perspective of email addressing for which IPv4 effectively restricts the use of zero values to the middle two octects (at least I don't believe you can use the network address) - does the same hold true for IPv6 does anyone know?
Similarly - apart from the two ranges (:: and ::FFFF:) for mixed environment representation of IPv4 addresses - are leading zeros allowed?
Assuming they are not (big assumption) then I've come up with the following for the domain-literal section of the expression:
\[(([a-fA-F1-9][a-fA-F\d]{1,3}|[a-fA-F\d][a-fA-F1-9][a-fA-F\d]{0,2}|[a-fA-F\d]{0,2}[a-fA-F1-9][a-fA-F\d]|[a-fA-F\d]{0,3}[a-fA-F1-9]):((([a-fA-F\d]{1,4}:){6})|(([a-fA-F\d]{1,4}:){4}:)|([a-fA-F\d]{1,4}:){3}:([a-fA-F\d]{1,4}:)?)|([a-fA-F\d]{1,4}:){2}:([a-fA-F\d]{1,4}:){0,2})|([a-fA-F\d]{1,4}:):([a-fA-F\d]{1,4}:){0,3})|(:([a-fA-F\d]{1,4}:){0,4}))([a-fA-F1-9][a-fA-F\d]{1,3}|[a-fA-F\d][a-fA-F1-9][a-fA-F\d]{0,2}|[a-fA-F\d]{0,2}[a-fA-F1-9][a-fA-F\d]|[a-fA-F\d]{0,3}[a-fA-
