It appears that these IPs are being used by Yahoo for WAP and the toolbar/personal search. I have referrers and UAs from: 66.94.237.140 to 147 toolbar.yahoo.com wap.oa.yahoo.com postfavorites (UA) and multiple generic UAs.
None without any UA or Referrer.

The one I mentioned in message 2 did not have a HTTP_REFERER header.
