I was wondering if it would be a problem having a dynamic IP with adsense? Let say my ip is 59.XX.XX.XX and after i reboot my router i get a new IP suppose 59.XX.XX.YY and i login into my adsense account with that IP, so will google get suspicious about the IP change? secondly what if one of the IP that i previously had goes to some other person and he clicks on one of my ads....will that be a problem?
No it wont. As for its only a probability of one in a million if that guy gets the same IP and also visits ur website and then clicks on ur ad - so chill out. You will be fine until you dont click your own ads.
I am sure there nothing to worry about, as long you don't click your own ads, It's normal if you are using ADSL connection, I also have this problem, but it's OK till now (2,5 yr).
