IPv6 is slower than IPv4 |
We would have to rewrite our entire application to support it |
We have no roadmap for native IPv6 as we rolled out 6RD. |
No one else has deployed it |
| We don't need that many addresses |

End users don't care about IPv6 |
| NAT444 is fine |

None of our customers want it |
Hex is hard |
