| It's on our roadmap |
None of our customers want it |
Our recursive DNS can't handle the extra load |
Too many people have broken IPv6 stacks |
It'll make it easier for the government to track me |
| We've still got plenty of IPv4 |
Our vendor doesn't support it |
IPv6 is slower than IPv4 |
Our business intelligence team can't even parse IPv4 logfiles |
It's too hard to support |
| There's no certification track |
What do you mean I have to wrap an IP in square brackets? |

Hex is hard |
What's IPv6? |
| We'll deploy IPv6 right after we deploy DNSSEC |
We would have to rewrite our entire application to support it |
I don't want to expose my MAC address |
End users don't care about IPv6 |
We have IPv6, but we just want to keep things simple |
| Larger headers are less efficient |
We can use RFC6598 |
I don't want to lose the security provided by NAT |
IPv6 is a security risk |
It'll break our GeoIP |
