IPv6 isn't an Internet Standard yet | NAT444 is fine | We don't need that many addresses | There's no ROI on deploying IPv6 | We've still got plenty of IPv4 |
IPv6 just isn't a priority | We'll deploy IPv6 right after we deploy DNSSEC | What do you mean I have to wrap an IP in square brackets? | IPv6 is just a fad | Azure doesn't support it |
We forgot to include IPv6 in our last RFP | We have IPv6, but we just want to keep things simple | Our recursive DNS can't handle the extra load | We can use RFC6598 | |
I don't want to lose the security provided by NAT | No one else has deployed it | Github doesn't support IPv6 | It's not mature enough | IPv6 addresses are too long to remember |
IPv6 isn't supported by OVH Cloud | Our Dynamic DNS doesn't support it | We don't have a lab to test it | I don't want to expose my MAC address | IPv6 is slower than IPv4 |
