> but haven’t come up with a persuasive reason for why they should. I don't know about you, but whenever I see an ISP, hosting provider, or website that supports IPv6 I think: These guys know what they are doing, they care about quality, and they actually plan for the future. I'd much rather do business with someone that supports IPv6 because of the above impression. If I was running my own business that provided network related products or services I'd make IPv6 support required because I don't want to seem like I'm incompetent/lazy/ignorant. So in short the persuasive reason is that it would improve their reputation. Technical people notice these things and base their recommendations on these sorts of impressions.
