There are not many domain names that in themselves would bring in this type of traffic. This domain is out for lease every now and then, because no one seems to be able to monetize it to justify the cost.
The domain name is most probably "oogle.com" and it has been offered here on GFY before, use the search function but some previous threads can be found here:

also offered here:

and here:

I could be wrong, but the traffic mentioned seems about right and the domain is being offered from time to time all over the place.
