Updated to v1.0.1 with this capability. One IP address per line, and it worked when I tested it... thanks for the suggestions everyone, let me know if anything doesn't work or if you have more suggestions.

I'm going to try and get to this next, so you can set if you want Registration IP checks, Post IP checks, or neither or both.

I will click install but need people to confirm it works on 3.5.2 :)

Will install when new version is up :)

.

Now updated to v1.0.2 with this capability. Please let me know if anything doesn't work, or if you have any suggestions.

Installed without a hitch !
Tested all aspects and its working beautifully !!

Brilliant hack Krofh, this is definately the best "prevent Multiple IP" hack exising.

.

Setting post IP's to maximumum of 1 could be a very bad thing... members move, and many members access forums from work. They would get really annoyed to not be locked out of their accounts..

Other than that the registration part of this hack could by very helpful. :)

This hack does not stop users from logging into their account from multiple locations (ie multiple IPs).

It stops users from registering 2 accounts from the 1 computer (or network).

There should be no reason why 1 user needs to have 2 accounts.

.

cool, did anybody try it on 3.5.2?

exacly what i needed thanks!
ill install :)

[high]* MissKalunji clicks install[/high]

I agreed, but I decided to just be more thorough and add all the features... you can always turn the post IP check off if you want.
