I think in order to see incoming connection on IPv6 you also need to host stuff on IPv6 and just how many people do that outside of academic research?
Hummm. That makes some sense Ė if my site isnít hosted on an IPV6 enabled server how would Apache know about IPV6 addresses.
OTOH, ISPís are starting to offer IPV6 to the minions and have a look at the SoftLayer post in this forum where blend27 provides a link Ė note the IPV6 range. So, what happens when an IPV6 user tries to connect to my website if it is hosted on an IPV4 server?
If a website serves just plain html it wouldnít know need to know if the IP was IPV4 or 6. But what if the website uses PHP and makes considerable use of $_SERVER['REMOTE_ADDR'] ?

it's an interesting subject that has bugged me for quiet some time. It is Definitely something to look into.
Thanks for the hint Lord Majestic.
We currently have 1090 Ranges(IPV4) that had been spotted as an abusive or simply belong to(waiting to get hacked, it is no brainier) of Datacenters and back bones on our watch list(a.k.a no soup for them) world wide. Most Large US ones already have IPV6 in their inventory.

Good point about $_SERVER['REMOTE_ADDR'] - I actually think for backwards compatibility they will always stuff IPv4 there, I think we will have IPv4 and IPv6 living next to each other for a very very long time, I'd be extremely suprised if IPv4 was totally switched off before 2020 or maybe even 2030 - the main issues with it were solved using multiple site hosting on same IP and also proxies.
I am guessing here but I reckon the main users of IPv6 (aside of networking companies) are the Internet2 research people. But again of your website is hosted on IPv4 then you won't see IPv6 address crawling you.
