The hostname should simply be the concatenation of "[IPv6:" with the standard 
IPv6 numerical notation, and "]".

So, if the source address is 2002:3e4e:969c::1, that would b 
[IPv6:2002:3e4e:969c::1]

Real-life example:

% nc6 2002:c2f2:7249::1 smtp
220 poy.chewa.net ESMTP Postfix (Debian/GNU)
EHLO [IPv6:2002:3e4e:969c::1]
250-poy.chewa.net
250-PIPELINING
250-SIZE 10240000
250-VRFY
250-ETRN
250-ENHANCEDSTATUSCODES
250-8BITMIME
250 DSN
...
