I'm attempting to find out information on the SEO implications of testing ipv6 out.

So basically I'd love to set up some sites for ipv6.domain.com via 6to4 as a phase one, and at some point in the near future implement ipv6 natively inside the datacenter, but I'm somewhat concerned about damaging SEO reputation in the process.
Thoughts?
Do we know which spiders run on IPv6?
After all an IPv6 only site may not be indexed at all...
I haven't published any hostnames, so I don't have the entire picture... with that being said, here's what I have seen. The only big search engine I've seen at this point is google, here are the user agents I've seen to date: Googlebot-Image/1.0 Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html) DoCoMo/2.0 N905i(c100;TB;W24H16) (compatible; Googlebot-Mobile/2.1; +http://www.google.com/bot.html) SAMSUNG-SGH-E250/1.0 Profile/MIDP-2.0 Configuration/CLDC-1.1 UP.Browser/6.2.3.3.c.1.101 (GUI) MMP/2.0 (compatible; Googlebot-Mobile/2.1; +http://www.google.com/bot.html) ----------- Just FYI, Google bots all have an ipv6 suffix of 6006:1300:b075 (Google Bots, how 1337 of them!) Here are the addresses seen from google: 2001:4860:4801:1302:0:6006:1300:b075 2001:4860:4801:1303:0:6006:1300:b075 2001:4860:4801:1401:0:6006:1300:b075 2001:4860:4801:1402:0:6006:1300:b075 2001:4860:4801:1404:0:6006:1300:b075 2001:4860:4801:1405:0:6006:1300:b075 2001:4860:4801:1407:0:6006:1300:b075 2001:4860:4801:1408:0:6006:1300:b075 ----------- And here's a breakdown of which user agents are seen on which ip, as you can see the user-agent doesn't exactly match IP range.
