In the organisation I work for we had IPv4/IPv6 dual stack. Due to IPv4 exhaustion my whole department was shoved behind an NAT, which given the circumstances I find it normal as there is no need for 400+ workstations to have public IPs. The weird thing is that after the switch to NAT IPv6 connectivity was lost. When asking why IPv6 was lost I was told "what do you need it for?".

In the meantime I have residential IPv6 since 2011. I really believe corporate networks are one of the main causes of delay in massive IPv6 adoption. And given the inertia I'm not really expecting them to change soon.
