[AFMUG] Dual Stack Gripe/worry

[Nate Burke]

I'm dual stacked at home, but it seems like I run into this issue about 
once a week. Content hosts need to do the same monitoring of their IPv6 
services as their IPv4 Services.  Many times the IPv6 site will break 
while the IPV4 site is fine.  Like right now, www.icontact.com is 
working from a V4 only box, but not a V4/v6 box, some sort of security 
certificate problem.  To a customer In a Dual stack environment, that = 
'Your service isn't letting me view that site'  (or as the wife yells 
down the stairs, The internet is down because this 1 site won't load)  I 
can see this only multiplying headaches as dual stack is rolled out 
across the network.  People who are already doing widespread Dual Stack, 
do you run into these issues?  If so, how do you solve them.  Disable V6 
on a problem box?  That kinda defeats the point then doesn't it.
