Cloudflare Show Real IP Address on CentOS Plesk Server
Cloudflare is a popular Content Delivery Network (CDN) that can greatly improve website performance and security. When using Cloudflare CDN, the server will report Cloudflare server IP as the visitor IP address. This is because when a visitor visit your website, they are visiting cloudflare server. Cloudflare server will fetch web page from your server, serve it to the visitor. So all access to your server is coming from Cloudflare server, not the real visitor. Cloudflare forward real visitor IP addresses in an HTTP Header “CF-Connecting-IP”. To make Apache show real visitor IP addresses, you can use the Apache module remoteip.
