inurl search -> AllTheWeb IP address?

[rankme]

My client's site is not indexed in either google or alltheweb.

Search on google inurl:ClientDomain.com spit out this result:
66.77.74.20/go/7/H/web/http/www.ClientDomain.com/

Clicking on the above link goes to ClientSite.com, with this URL displayed in the browser:
[ClientSite.com...]

66.77.74.20 is an IP address for alltheweb

I've never encountered something like this before. Does anyone understand this? It appears that old FAST results are stored somewhere at google?

Searches here didn't turn up anything about this, so point me to the right thread if this is old, familiar territory.

(and yes, I am a bit obsessive. 3 recent posts about 1 problem site :-> )

That's an (old) click through url from ATW. So the site has been indexed by ATW at one time.
Google must have picked up the url somewhere.
