For safety, i would use 48, to allow zero termination
why 48 when max length of ipv6 addr is 39 chars? did you mean 40?
text representation can use ipv4 format for last 4 bytes:
http://tools.ietf.org/html/rfc4291#page-4
common for cases when tunneling ipv4 over ipv6.
That is:
(6 * 4 + 5) + 1 + (4 * 3 + 3) = 45
Then add 3 for the square brackets and the ending 0.
Cheers, Daniel
