there are number of people using IPv6 in day to day work. I'm ssh'ing
to my mail server over IPv6 while i'm writing this, thanks to
IPv6 support in OpenSSH. it is almost unnoticeable because the IPv6/
IPv4 address selection is hidden in DNS lookup. I did:
% ssh coconut.itojun.org # my mail server
and since it have got translated into IPv6 address, ssh client
used IPv6.

i usually do not use IPv4 from my laptop. I use IPv4 indirectly,
only when I contact IPv4 web/mail/whatever servers, via IPv6-to-IPv4
translators. i've attached interface configs on my laptop.
notice that there's no IPv4 address except 127.0.0.1.
in my home 5 to 10 machines are up and running, and they are using both
IPv4 and IPv6. when I contact them from outside, I usually use IPv6.
when you see AAAA DNS records, that host has an IPv6 address and
is expecting other to connect to that machine via IPv6.
for example, try:
% dig ftp.iij.ad.jp. aaaa
% dig ftp.kame.net. aaaa
% dig ftp.6bone.net. aaaa
