Both support IPv6, either using the opt-in mechanism or by using an alternate CNAME (ghs46 instead of ghs.google.com). That's what I use.
None of the other large "cloud" providers seems to support IPv6 for their users yet. In particular, neither Amazon's AWS not Microsoft Azure have much visible activity in this direction. Rackspace have announced IPv6 support for the first half of 2011. Concerning the more traditional webhosting offerings, I have no idea about the "big boys". Here in Switzerland, a few smaller hosters support IPv6. And I saw IPv6 mentioned in ads for some German server hosting offering. Germany is interesting because it has a well-developed hosting ecosystem with some really big players. -- Simon.
