IPv6 Excuse Bingo| We would have to rewrite our entire application to support it | IPv6 is a security risk | AWS doesn't support it | Azure doesn't support it | It'll make it easier for the government to track me |
| We can use RFC6598 | Larger headers are less efficient | We don't have a lab to test it | Those stupid Privacy Extension addresses keep changing | We have no roadmap for native IPv6 as we rolled out 6RD. |
| Our Dynamic DNS doesn't support it | IPv6 addresses are too long to remember | |
IPv6 is just a fad | There's no ROI on deploying IPv6 |
| Hex is hard | Too many people have broken IPv6 stacks | IPv6 isn't supported by OVH Cloud | We'll deploy IPv6 next financial year | Android doesn't support DHCPv6 |
| It's too hard to support | Did you mean IPTV? | IPv6 is slower than IPv4 | My transit provider doesn't support IPv6 | NAT444 is fine |
