IPv6 Excuse Bingo| Our business intelligence team can't even parse IPv4 logfiles | It's not supported by Google Compute | IPv6 isn't an Internet Standard yet | We have IPv6, but we just want to keep things simple |
| We have no roadmap for native IPv6 as we rolled out 6RD. | Larger headers are less efficient | I don't want to lose the security provided by NAT | It'll break our GeoIP |
| It's too complicated | It's on our roadmap | IPv6 is slower than IPv4 | NAT444 is fine |
| Our DDOS mitigation platform can't monitor IPv6 | Android doesn't support DHCPv6 | No one else has deployed it | Our Dynamic DNS doesn't support it |
