Are are all ip addy's unique?? I'm not quite sure and from what I can gather the answer is no. Anyone want to help me out on this one?
If they aren't all unique does anyone know a good way to track users? For instance, I want to make sure people don't join my site twice but I'm hesitant to use IP address... I would use cookies but they can be deleted. Any ideas?

Moderator: General Moderators
Cookies: Impossible. They are deletable and what if someone uses a different browser/computer?
IP: Bad. Most peoples addresses change contsantly, even if you have high speed it's changing a few times a month (in most cases).
Email: Horrible, yet ok. If it's that important you don't want someone to join twice, don't use this. Otherwise this is the best bet. Store the emails in a db, then send an authorization code to the address on registration. You will need to keep a log of the logins from each account and which IPs they use to make sure they don't have multiple accounts.
That is the security measure i'm taking for a site i run. It's an online game and it's critial nobody has more than one empire.
