note 35285 added to function.ip2long

After reading this page I am still confused. I don't exactly know how I should go about this project I need. I have several Class C IP blocks as well as several different systems. Each system has 1 to 5 C classes assigned to them. I am searching for a way to be able to plug in an IP address and then the php return which system that IP belongs to. This may not be the correct section. Can anyone help or direct me to a more approproate help section?
