Can anyone tell me how many adsense account can we use with one IP address because I have already adsense account but now my brother has also got adsense account but we both use same computer and same IP address and therefore I am afraid.
well every person can have ONE ADSENSE ACCOUNT FOR LIFETIME irrespective of the IP address or anything you and your brother can create adsense accounts for themselves and google won't be having any issues with that
You must have only one account in person but there is no meaning to use One Account with One IP Address.
Beware though that Google may think you are one person with two accounts. Try a quick email to them to explain?
One Account Per Person. That's google's take. Nothign about IP etc. However, two persons using the same IP and having different accounts will have a higher risk of getting their accounts suspended if one of them inadvertently clicks on the other person's ads multiple times.
