IPv6 Excuse Bingo| It'll break our GeoIP | I don't want to expose my MAC address | We forgot to include IPv6 in our last RFP | Our Dynamic DNS doesn't support it |
| What's IPv6? | None of our customers want it | Too many people have broken IPv6 stacks | IPv6 is slower than IPv4 |
| We don't need that many addresses | We can use RFC6598 | We've still got plenty of IPv4 | End users don't care about IPv6 |
| AWS doesn't support it | What do you mean I have to wrap an IP in square brackets? | Our DDOS mitigation platform can't monitor IPv6 | It's not mature enough |
