I found four ip address 64.68.82.199 , 64.68.82.10, 64.68.82.137, 64.68.82.44, 64.68.82.14 in a gap of 10 hrs. These are all google address but why 4 different robots ( of google ) are checking my site in a short gap ? Any idea ? Any thing I have to do or modify my site for these guest's next visit

?
