go IPv6, fade out IPv4

I don't think they are interested in any replies but this is just a
spam email for "buy our ipv6 service"
That is how I read it. It describes no problem, aside from globally
routable ip4 addresses becoming scarce and expensive, which I doubt
applies in any meaningful way to a SMB server,
and it describes no solution or action plan, aside from "we don't read
mailinglist replies, contact us directly".

In my opinion this is just a fraction above getting a phone call from
"This is from internet office for microsoft, you have virus and must
buy pre-paid google-store payment cards and we can restore internet"

Am impressed they did personalize the spam/scam email and even wrote
many paragraphs.  10/10 for effort.
