DOC: proxy-protocol: clarify IPv6 address representation in the spec

Browse Source

indicated as series of 4 hex digits" is confusing and can be interpreted
two ways (only 4 digits or series of sets of 4 digits), so let's adjust
the wording to resolve this ambiguity.

written in decimal representation separated by exactly one dot between each
other. Heading zeroes are not permitted in front of numbers in order to
avoid any possible confusion with octal numbers. IPv6 addresses must be
indicated as series of 4 hexadecimal digits (upper or lower case) delimited
by colons between each other, with the acceptance of one double colon
sequence to replace the largest acceptable range of consecutive zeroes. The
total number of decoded bits must exactly be 128. The advertised protocol
family dictates what format to use.
