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.

Again, I don't have the entire picture because I've not published my hostnames. The above information is just what I've seen on my selective testing.
