Complete IP ranges are with four separate classes or ocets.
Example
216.239.37.104 (which is a result of searching google on 37.104.)
or
37.104.xxx.xxx which are un-assigned reserved ranges.
The entire 37.xxx.xxx.xxxx ranges are reserved.
Do your logs show the visitor coming from
216.239.37.104 and 216.239.39.104 [Which is Google]
or
37.104.xxx.xxx [which would be a faked IP]
