Azure doesn't support it | Our business intelligence team can't even parse IPv4 logfiles | AWS doesn't support it | Our Dynamic DNS doesn't support it | We forgot to include IPv6 in our last RFP |
Our DDOS mitigation platform can't monitor IPv6 | Github doesn't support IPv6 | Our recursive DNS can't handle the extra load | Did you mean IPTV? | We would have to rewrite our entire application to support it |
IPv6 is a security risk | We can use RFC6598 | IPv6 isn't an Internet Standard yet | Can't we just buy more IPv4 addresses? | |
Android doesn't support DHCPv6 | Larger headers are less efficient | What's IPv6? | Our vendor doesn't support it | None of our customers want it |
NAT444 is fine | IPv6 addresses are too long to remember | It's on our roadmap | Those stupid Privacy Extension addresses keep changing | We've still got plenty of IPv4 |
