If you use 4-in-6 mapped format, omit zeroes compression and add square brackets, you get 47 characters:

why would someone use such a format when there is canonical format specified in http://tools.ietf.org/html/rfc5952?
I don't know why, but http://en.wikipedia.org/wiki/Robustness_principle
in this rfc and in http://en.wikipedia.org/wiki/IPv6_address i was not able to find anything about the format you gave example above. where is it specified?
Under "dotted-quad notation", minus "leading zeroes" and minus "groups of zeroes" (note the little word "may" in both of these sections), plus "Literal IPv6 addresses in network resource identifiers".
