Track all Duplicate IP Addresses via Admin CP

Duplicate IP tracking v1.2 by Jolten

Be gentle, this is my first release.

What's this do?
This hack is an admin control panel addition. It will render a complete list of all users with duplicate IP addresses in your forums. And adds very little in terms of queries and sever load. This is designed to help those site admins, who wish to, to track users which may have duplicate accounts.

Be aware that many internet service providers (AOL, JUNO, NetZero) may assign the same IP to many different users. A duplicate listing is not an immediate indication of a duplicate account by the same user.



Installation
Files to edit -- 1
Phases to add -- 2
Files to upload -- 1
Database alterations -- None
Total Queries -- 3

Time to install -- Less than 5 minutes

Support
I can't promise full support but I will do all I can to fix any bugs or answer all questions. All support must be done strictly through this thread. If you are using this hack, please click the INSTALL button to be informed of any future updates, add-ons and bug fixes.


Enjoy!

Screenshot Below
It should be noted (since the screenshot doesn't show it due to my censorship of the names) that the list of usernames links directly to the adminCP user options for that user, allowing easy access to the users information.

There is just one problem with this hack. If 2 users are registered on the forums and are living nearby (neighbours I mean), there IP address will show up the same thing. Because they both live in the 'same' country so you won't notice properly if a user has multiple accounts or not. It may be a person who is so close to your country that will use the same IP as yours, or a person who has registered multiple accounts. That is the only problem with this hack. :tired:

IP ranges may be similar. But IPs should never be identical just because users are neighbors unless they are using something like AOL.

that doesn't really make any sense...

What do you mean it doesn't make any sense?

Now your post doesn't make any sense and is pointless.

This is very good especially to flush out people that are using multiple names, however I want to ask is there anyway to to attache user names to these ips? so u will be able to know who is using more than one id in your forum.

is there?

thanks and by the way this is good hack

as Jolten said, neighbors don't/shouldn't have the same ip address (unless one is taking advantage of the other's unencrypted wireless network. )

Just installed. Looks good :up:

I have a suggestion for future release.

1. Add a page jump
2. Allow sorting by the number of duplicates.

I selected to disply 250 per page, and still got 67 pages So a page jump would be handy.

Have installed the mod and in first view I like it much.

Install is clicked

On the list.
I do not know that I'll be updating for v3.5 though. My site is fine at 3.0.7 and I see nothing in 3.5 that warrants my upgrading.

The first 7 are AOL banks and the last one is WebTV.

Can anyone give an example of implementing this into the script?

TIA
