I've re-released this addon with help from a suggestion by @Liam W.

If you are using CloudFlare, and do not already have a means to extract the correct IP address from a visitor, normally done at the web server level, you may need this addon.

This addon will replace the Cloudflare IP of visitors with their actual REMOTE_ADDR IP address. This code is based on the same code that the CloudFlare Wordpress addon uses.

You may choose to use this add-on if:
  1. Your host will not, or cannot, install a CloudFlare compatible add-on for your web server (i.e. HttpRealipModule for Nginx or mod_cloudflare for Apache).
  2. You don't want to add code suggested by CloudFlare to your config.php or index.php file to try to determine a user's originating/true IP address.
About this Add-On

This add-on, when enabled, will check to see if your site is being served by the CloudFlare system. If it is, it will check to see if the visitors's IP address matches one on CloudFlare's network. If it matches, the user's REMOTE_ADDR is set to the originating IP address (HTTP_CF_CONNECTING_IP).​
This add-on supports both IPv4 and IPv6 addresses.

This add-on will be updated with the current list of CloudFlare based IP's on a routine basis. Users who download this add-on can also manually update these IP addresses themselves in the administration options.

This add-on includes a third party function named "ip_in_range" that is packaged with the CloudFlare WordPress add-on, provided by Paul Gregg, located at http://www.pgregg.com/projects/php/ip_in_range/

If you have changed your config.php or index.php file to reassign HTTP_CF_CONECTING_IP to a visitor's IP address, that code can be removed after installing this add-on.

Installation Instructions
  1. Upload contents of "upload" folder to your xenForo installation.
  2. Install the add-on with the "addon-cf_detect.xml" file.
The only options available for this addon are the lists of IP4 and IP6 addresses that CloudFlare uses. These options have a link to the IP addresses that CloudFlare uses, and should be kept current at all times. You may occasionally want to verify that these options match what CloudFlare says its IP's are, but I will update this addon from time to time when more IP's are added.

Perfect addon if you use Cloudfare, plug-and-play, install and it's work perfectly if you had errors withs users IPs. :)
Thanks for the review tatin1998
Great addon, does what it says and provides help for finding actual users IP addresses instead of having cloudflare proxy all IP's.
Thanks for the great review Wororfight, I certainly appreciate it.
