IPv6 Excuse Bingo| Github doesn't support IPv6 | AWS doesn't support it | It's too complicated | I don't want to expose my MAC address | IPv6 is slower than IPv4 |
| It's not supported by Google Compute | What's IPv6? | IPv6 isn't supported by OVH Cloud | IPv6 isn't an Internet Standard yet | We don't need that many addresses |
| I don't want to lose the security provided by NAT | End users don't care about IPv6 | |
We have IPv6, but we just want to keep things simple | NAT444 is fine |
| We have no roadmap for native IPv6 as we rolled out 6RD. | Our Dynamic DNS doesn't support it | We can use RFC6598 | None of our customers want it | We would have to rewrite our entire application to support it |
| Larger headers are less efficient | It's on our roadmap | Can't we just buy more IPv4 addresses? | IPv6 is a security risk | Our DDOS mitigation platform can't monitor IPv6 |
