Android doesn't support DHCPv6 | We forgot to include IPv6 in our last RFP | Azure doesn't support it | Hex is hard | IPv6 isn't an Internet Standard yet |
We have no roadmap for native IPv6 as we rolled out 6RD. | We have IPv6, but we just want to keep things simple | We can use RFC6598 | Our Lawful Intercept doesn't support IPv6 yet | I don't want to lose the security provided by NAT |
Larger headers are less efficient | It's on our roadmap | Our DDOS mitigation platform can't monitor IPv6 | Those stupid Privacy Extension addresses keep changing | |
It'll make it easier for the government to track me | No one else has deployed it | There's no ROI on deploying IPv6 | Did you mean IPTV? | Our recursive DNS can't handle the extra load |
I don't want to expose my MAC address | NAT444 is fine | It'll break our GeoIP | IPv6 is a security risk | IPv6 is slower than IPv4 |
