IPv6 Excuse Bingo| It'll make it easier for the government to track me | It'll break our GeoIP | Our recursive DNS can't handle the extra load | AWS doesn't support it |
| What's IPv6? | IPv6 isn't an Internet Standard yet | I don't want to expose my MAC address | It's too hard to support |
| IPv6 is just a fad | My transit provider doesn't support IPv6 | Github doesn't support IPv6 | IPv6 is slower than IPv4 |
| Too many people have broken IPv6 stacks | It's not mature enough | We don't have a lab to test it | It's not supported by Google Compute |
