just an FYI, many web users using a proxy connection and [i]all[/i] AOL users have ip addresses that change, often everytime they load a new page.

Thank you for your response m8.
But my problem is with the script not the user ex. When i vists it for the first time with my ip it will print out Hello World but later when i try reaching the page from another ip it give's me google instead of Hello world :( that is what needs to be fixed if you can see the problem please tell me how to modify it


Best regards
