Our DDOS mitigation platform can't monitor IPv6 | It's not mature enough | Azure doesn't support it | I don't want to expose my MAC address | IPv6 is a security risk |
IPv6 just isn't a priority | It's too hard to support | Github doesn't support IPv6 | IPv6 isn't an Internet Standard yet | IPv6 is just a fad |
We forgot to include IPv6 in our last RFP | It's on our roadmap | Too many people have broken IPv6 stacks | Our business intelligence team can't even parse IPv4 logfiles | |
Those stupid Privacy Extension addresses keep changing | IPv6 addresses are too long to remember | Vendor bugs | We would have to rewrite our entire application to support it | IPv6 is slower than IPv4 |
We have IPv6, but we just want to keep things simple | Android doesn't support DHCPv6 | We can use RFC6598 | It's too complicated | End users don't care about IPv6 |
