IPv6 Excuse Bingo| Those stupid Privacy Extension addresses keep changing | Larger headers are less efficient | It's on our roadmap | End users don't care about IPv6 | What's IPv6? |
| Can't we just buy more IPv4 addresses? | It'll make it easier for the government to track me | None of our customers want it | Our recursive DNS can't handle the extra load | IPv6 is slower than IPv4 |
| Did you mean IPTV? | It's too hard to support | |
Our DDOS mitigation platform can't monitor IPv6 | IPv6 isn't supported by OVH Cloud |
| Vendor bugs | My transit provider doesn't support IPv6 | AWS doesn't support it | NAT444 is fine | I don't want to lose the security provided by NAT |
| IPv6 is a security risk | I don't want to expose my MAC address | We would have to rewrite our entire application to support it | IPv6 is just a fad | No one else has deployed it |
