Cloudflare Restore Original Visitor IP

Restoring original visitor IP address in cloudflare is easily done by utilizing the header CF-Connecting-IP header.

Cloudflare being the fastest Free DNS provider and one of the most commonly used CDN(Content delivery network). Most of us use cloudflare as the primary dns provider instead of using the dns service provided by the domain registrar.

So when we use cloudflare as the primary dns provider and have the traffic served through cloudflare proxy it helps in masking the original ip address of the server, thereby hiding the original service provider.

This is a very useful feature provided by cloudflare DNS which is available even in the free plan where the cloudflare will protect your website and server from bots and only pass clean traffic to your servers.

On the down side cloudflare while passing the user traffic it also masks or proxies the original visitor ips and your apache server logs will only show the internal private ip addresses of cloudflare and not the original visitor ips.


This makes it very difficult when you analyse your server log files or sometimes we restrict admin access to only specific ip address (for example granting access to admin pages only to a specific range of ip address of your home or office). In this case, you will not be able to efficiently have access control based on ip addresses.

Mod_remoteip an apache module can be used along with cloudflare to restore visitor ip (original visitor ip) if you are using apache server it is very simple to configure it.
