| There's no certification track |
Our vendor doesn't support it |
IPv6 just isn't a priority |
IPv6 isn't an Internet Standard yet |
It's on our roadmap |
| We can use RFC6598 |
It's not mature enough |
Github doesn't support IPv6 |
No one else has deployed it |
It'll break our GeoIP |
| I don't want to lose the security provided by NAT |
What's IPv6? |
 |
We don't need that many addresses |
We forgot to include IPv6 in our last RFP |
| Our DDOS mitigation platform can't monitor IPv6 |

We'll deploy IPv6 next financial year |
Those stupid Privacy Extension addresses keep changing |
| It's too complicated |
Vendor bugs |
Larger headers are less efficient |
We would have to rewrite our entire application to support it |
IPv6 is a security risk |
