IPv4 to IPv6

[James B. Byrne]

We are beginning the process of transitioning to IPv6.  I have read a
great deal respecting the difficulty of moving from IPv4 to IPv6 and
maintaining general Internet connectivity.  If any reading this have
gone through the process upon which we are embarking then I would be
grateful if you share your experience. Particularly any 'gotchas' that
cropped up.

We will be using FreeBSD-11 as the platform for our Internet
connectivity. The main services we provide publicly are SMTP and DNS. 
We will maintain IPv4 addresses for these together with IPv6.
