One IP address per login

Some colleagues are making a community website/forum and wanted to make sure people don't register dummy accounts (all you need are email addresses to register).

Is it fair to limit 1 registration per IP Address? Or does that not make sense to do? (for example, people logged on from a cafe cannot register since someone already used that IP address to register).

Or does anyone have a better idea to preclude multiple registrations from the same person? Sorry for my ignorance...

Thanks for the reply.

So websites detect if there's 2 different users logged in with the same IP and then forbid that?

Can't do that on a free site 🙂

We want to encourage people in joining by making it very easy to register. But we want to keep the malicious motives out...

Usually you can't have both. You could always deal with the people who are not wanted and install a pay email register system later after you are established. Most people who you want there would have pay emails anyway.

Use one of those scrambled words where you have to type in the word. So bots can't make thousands of accounts.
 
Why not only permit x registrations/logins per IP in a certain time frame.

That way someone can't hop from account to acacount off of one IP, but it doesn't prevent different people from accessing it.

Good input, but let me clarify - its an auction type site. So malicious people might make a login to post something. Then make another login a few days later to bump up his price.

I guess this is impossible to guard against. Unless we do something like 1 IP per account only which might be unfair...
 
The 1 IP per person is the most retarded thing I've ever heard.

I can't believe I'm even typing this ... 'cause it's wasting my life ... BUT

Maybe you've heard of AOL? Or proxies perhaps? NATs & Firewalls?

Yeah, many people, 1 IP. Good luck with that.

Sorry for not being as knowledgeable as you 🙂

Its why I'm asking the question here... I'm a senior chip designer in my 30's. I'm not in touch with "the internets"

Do you mind explaining some more, or are you wasting your life? 🙂

^ Listen to him.

Thanks to AOL and other proxying/NAT services, IP addressing methods are almost always a complete failure (unless you block services that do things like that...)

Thanks. So common locations will be ruled out. Our clientele would be older and likely to do their work on our site from their home or office exclusively.

So I'm not sure if I can rule the singular IP out yet?

You would be locking out people from using public computers? Like, only one person could register at a single library.

Or what abuot peopel who post from many different computers (I post from home, school and 2 libraries)?
 
There are a number of ISPs who use web proxies - some have an optional proxy (you configure it in IE or mozilla/ff) or transparent (all data goes through it automatically, the end user can't change this). All traffic that goes through the proxy, will appear to come from the proxy's IP.

It's not just AOL. Many ISPs do this, as do many schools/universities. An example, I've come across recently (setting up a web site for med students) is internet access in hospitals in the UK. All internet traffic from all UK is routed through a single proxy, and appears to have the same IP.

Thanks for the explanation Mark. Appreciate the layman terms 🙂
 
Everyone at my company who goes to that website will appear to the server as having come from the same IP address: our proxy server.

The plan you describe simply will not work in today's Internet environment. Too many users are behind proxies/NAT boxes that will cause multiple users to appears as though they are on the same IP address.

Would that be a something like a Lays Wavy Engineer?

The easiest solution would be a verified email address, restricting free ones. Allowing only one login session for an account at any given time.

Yes, using something called Dynamic Host Configuration Protocol (DHCP), which assigns an IP address to a machine that connects for a specified period of time (usually the length of the connection).

When the user disconnects, they "hand back" that IP address to the list of addresses that the server is allowed to assign. Thus, if someone else then connects, there's a chance that they now rent the IP address from the first user.

Conversely, you can also be given the same IP address again if you reconnect immediately, but it's luck of the draw.

Yep I'm convinced.

I guess we'll just pay an admin to watch out for malicious users and note identical IP's just for tracking purposes...

Thanks
 
use multiple cookies to watch for it (have a login cookie, and a seperate tracking cookie)

that way you're not boning the people at large corporations, colleges, and other places that have dozens/hundreds of people using a single IP
