What is ik-out-f136.google.com?

[apauto]

There is a "ik-out-f136.google.com" surfing my site right now. It's not coming up as Googlebot, could this be a human evaluator looking at my site right now?

Anyone have any experience with a domain like this?
Thanks,

Here's an earlier thread about that one. Looks to be a bot and not a human:

If it is coming from somewhere within the 66.249.91.nnn block (presumedly 66.249.91.136 itself), then it is coming from (or via) Google itself.
