Wazzat?  Isn't the C for Carrier?  So, not my problem.

I got a /24 from my provider years ago.  I only use half of it.  If we
needed to economize we could probably go ahead and deploy name based
virtual hosting, the server guys have talked about that for years.  I 
can't imagine I will ever run out of IPv4.

IPv4 currently has more reach than IPv6?  Didn't you just tell me people
aren't deploying IPv6.

I can't find it in the docs for our IBM Token Ring switch that connects
the payroll mainframe to the ERP NEC box.  That's our only critical
application.

I thought all the providers were deploying that CGN thing so IPv4
kept working.  They would never leave us high and dry, right?

I was told DNS64 fixed that problem, and carriers would have to deploy
it as a transition strategy.

My IPAM software doesn't have AAAA support because I haven't bought a 
support contract for it for 10 years.  Do I really need to buy new
IPAM software?

Actually it's more my boss has 100 "critical" initiatives and staff
to do 20 of them, and IPv6 isn't even on the list.  Our planning window
is crisis to crisis, err, I mean quarter to quarter.  Will my web site
go down this quarter if I don't deploy it?  Otherwise we can put that
off.

Sadly, I wish all these answers were some sort of carachture of reality,
but I think they are too many folks reality.
