IPv6 Excuse Bingo| Those stupid Privacy Extension addresses keep changing | Vendor bugs | IPv6 is slower than IPv4 | Our recursive DNS can't handle the extra load | There's no ROI on deploying IPv6 |
| I don't want to lose the security provided by NAT | IPv6 just isn't a priority | Our business intelligence team can't even parse IPv4 logfiles | Too many people have broken IPv6 stacks | IPv6 is a security risk |
| I don't want to expose my MAC address | No one else has deployed it | ![]() |
AWS doesn't support it | Our DDOS mitigation platform can't monitor IPv6 |
| Did you mean IPTV? | It's not supported by Google Compute | We have no roadmap for native IPv6 as we rolled out 6RD. | We'll deploy IPv6 next financial year | Can't we just buy more IPv4 addresses? |
| Our Dynamic DNS doesn't support it | Larger headers are less efficient | Github doesn't support IPv6 | We've still got plenty of IPv4 | It's too hard to support |
