| We forgot to include IPv6 in our last RFP |
IPv6 is a security risk |
I don't want to lose the security provided by NAT |
Hex is hard |
IPv6 addresses are too long to remember |
| It'll make it easier for the government to track me |
It'll break our GeoIP |
None of our customers want it |
IPv6 is just a fad |
Our Dynamic DNS doesn't support it |
| It's not mature enough |
Larger headers are less efficient |
 |
What do you mean I have to wrap an IP in square brackets? |
It's too complicated |
| Vendor bugs |
We have IPv6, but we just want to keep things simple |
We'll deploy IPv6 right after we deploy DNSSEC |
NAT444 is fine |
We don't have a lab to test it |
| End users don't care about IPv6 |
Azure doesn't support it |
There's no certification track |
We don't need that many addresses |
We can use RFC6598 |
