Ipv6 ftw

First we install miredo and libao-dev (needed to compile inadyn-mt below)

sudo apt-get install miredo libao-dev

Now if you check your ifconfig you'll have an ipv6 address.

Grab inadyn-mt from http://sourceforge.net/projects/inadyn-mt/. Compile and install it.

wget http://superb-sea2.dl.sourceforge.net/project/inadyn-mt/inadyn-mt/inadyn-mt.v.02.24.36/inadyn-mt.v.02.24.36.tar.gz
tar xvzf inadyn-mt.v.02.24.36.tar.gz
cd inadyn-mt.v.02.24.36
./configure
make
sudo make install

Sign up for an account at dyndns.org and create a new host. Now add this line to a file in /etc/cron.d/hourly:

inadyn-mt --ip_server_name checkip6.zerigo.com -u USERNAME -p PASSWORD -a HOSTNAME.dyndns.org ip6 --iterations 1
