I utilize the "Allowed Sites" feature of Adsense and only list my websites. But here is what has been showing up: ______________________ Unauthorized Sites The following sites are not on your Allowed Sites list but have displayed ads using your AdSense publisher ID within the last week. 74.125.93.104 74.125.45.104 209.85.171.104 209.85.135.104 209.85.175.104 66.196.80.202 74.125.95.104 74.125.39.104 203.208.33.101 74.125.113.104 66.163.168.225 ___________________________________ It seems that most are Google IP addresses, possibly when someone views my sites in cache mode. Is it safe to add these IP addresses to my list of allowed sites?
No, I do not think that it is good, i think these all are mostly not just google IPs but all are actually Search Engines IP like yahoo and all but do not add into trusted site list
