Sounds as if yours was just recently pulled from it.  :-) :-)

You do realize my "suggestion" was only meant to address a single issue by a single user.  Right?

Yet, if an ISP supplies only IPv6 services you'd think they would also either supply you with a  DNS64/NAT64-resolver address or inform you that you should use one of the public DNS64/NAT64-resolvers.  I suspect that is how you got your appliance working in that environment?

At home, I got one of the first HE-tunnels, at the time that they were only located in Fremont, and a happy camper ever since.
At work however, this quite another struggle :-((((((

And yes, Ed, I realise that disabling V6 is some duck-tape (not even a Q&D-fix) to get-on for a while.
Unfortunately, googling on it, this is suggested way too often as a permanent solution.
That location used indeed DNS64 and NAT64, that worked for almost all my laptops, phones etc, but not for my box.
Reason? One of my colleges had also disabled V6 on the readonly appliance. Sigh.
So when  I see that suggestion, I stand up  :-)
