I ask in the most genuine way possible: Why? IPv6 is for when you can't get an IPv4 address anymore. To the best of my knowledge, there aren't currently users with only IPv6 addresses, so there's zero reason for us to support it. In the general case, why should any IPv4 website bother with IPv6? Is there any benefit?

To set an example and encourage IPv6 adoption. Many people think IPv6 is going to fizzle, and as justification they point to the currently low adoption rate of IPv6. I'm very afraid this will become a self-fulfilling prophecy and we will be stuck with a future where home users are forced to use carrier-grade NAT and even web site operators may have a hard time getting new IP addresses. I want to avoid that future if at all possible, so I do everything I can to encourage IPv6 adoption today. There may be no short-term benefit but helping IPv6 adoption has substantial long-term benefits.

In some networks (e.g. Verizon) IPv6 should be slightly faster and more reliable since it doesn't go through CGN.

- Carrier-grade NAT forces users to share IPv4 addresses, making it difficult to ban offenders without collateral damage. This problem is only going to get worse. - NATs are full of state, and state is messy. Making your site route around them may improve performance. - This is one of the few areas where software people can directly make the world a better place, by preventing "our" Internet from regressing into something that more resembles the telco network. - Lack of IPv6 support strains the credibility of companies that purport to be on the forefront of technology. Google, Facebook, and Wikipedia (and Bing?!) figured this out; why can't Hacker News? - It gives your site a green 6 in IPvFoo, instead of a red 4. Six is 2 better than four, and green is 100THz better than red.
