There's no ROI on deploying IPv6 | It's too hard to support | We don't have a lab to test it | Hex is hard | None of our customers want it |
IPv6 just isn't a priority | Our vendor doesn't support it | We'll deploy IPv6 next financial year | IPv6 is just a fad | Larger headers are less efficient |
Our Dynamic DNS doesn't support it | What's IPv6? | Github doesn't support IPv6 | IPv6 isn't an Internet Standard yet | |
AWS doesn't support it | IPv6 addresses are too long to remember | There's no certification track | Those stupid Privacy Extension addresses keep changing | Vendor bugs |
Our Lawful Intercept doesn't support IPv6 yet | No one else has deployed it | Our DDOS mitigation platform can't monitor IPv6 | IPv6 is slower than IPv4 | IPv6 is a security risk |
