that link is dead (403 - forbidden) but seems to address the differences between ipv4 and ipv6.
he was asking why you'd need ipv6 support for a CDN, which is mostly hosted by other people. you only reference it in your html code, once. so his question would probably still be unanswered, even if your link worked.
