Different Computer = Different IP? For contest.

Ok there's this PGA internet contest I've heard of, and basically long story short each person is only supposed to make one account, and if you make more than one you get disqualified. Obviously I know they can find out if you make more than one account based on your IP, if you were dumb enough to do it on your own computer. But what if you went to a internet cafe or something? Or even a school? Is there anyway they could connect the two accounts as being the same person? I know you can also use a proxy server, but I've heard there are ways to find out the real IP from them.

Why do you want to break the rules?

I don't necessarily want to break the rules, I'm just curious as to whether or not it's possible. In the rules it says they'd find out, so I'm wondering how exactly.

There is an IP address and mac address.
In addition if one hits the other account that could tie the two accounts together.
Bottom line is that after the contest ends, the scrutiny begins.

So essentially what you're saying is if somebody were to log onto Account B from Account A's IP address or MAC address, then they would be linked?

I don't think that is common knowledge, but I might be wrong. I just get the feeling alot of people will be trying to cheat, so as long there are actually ways to catch em, then that's good.

Also is it possible to find out someones IP address/MAC address from an email?

It is easy to see which IP's a person has historically used to access an account and what accounts were accessed by a given IP. That is a basic feature of vBulletin and other forum software. (Read your PM's.)

Also, in order to win whatever the prize is... I assume you would want to provide your true identity when registering, to ensure your ability to claim said prize should you win.

I am not that into networking, but I thought that a MAC addresses isn't readily available to a website like an IP address would be. As long as your IP address was different and there wasn't a cookie somewhere on your comp, then they wouldn't have much luck figuring out it was you.

You are right. The MAC address is only in the ARP header and lower layer protocols. As Jester said, one needs to use legitimate info when setting up an account in order to receive a physical prize. That info is easily cross checked as is matching all IP's that access each account.

As long as you use different information and different computers on different networks, you do this.

Create account A with computer A.
Create account B with computer B.

And so on. Just don't make the mistake of logging into A with B or B with A. Got it?
