IPv6 Excuse Bingo| Our Lawful Intercept doesn't support IPv6 yet | It's not mature enough | IPv6 is slower than IPv4 | End users don't care about IPv6 | Our DDOS mitigation platform can't monitor IPv6 |
| We don't have a lab to test it | NAT444 is fine | I don't want to lose the security provided by NAT | IPv6 is a security risk | We've still got plenty of IPv4 |
| It's too hard to support | We'll deploy IPv6 right after we deploy DNSSEC | |
We can use RFC6598 | IPv6 isn't an Internet Standard yet |
| Larger headers are less efficient | None of our customers want it | Vendor bugs | IPv6 isn't supported by OVH Cloud | We don't need that many addresses |
| No one else has deployed it | Those stupid Privacy Extension addresses keep changing | What's IPv6? | Too many people have broken IPv6 stacks | AWS doesn't support it |
