How to find the real IP address of a website behind Cloudflare

Cloudflare is a web performance and website security company that provides services like CDN (Content Delivery Network), WAF (Web Application Firewall), DNS management, and security from attacks like DDoS.

More than 5,000,000 websites use Cloudflare to improve their loading speed, reduce the load on origin servers and prevent various online attacks.

Since Cloudflare is a reverse proxy service, it acts as an intermediary between website visitors and the host server. This makes it very hard for anyone to find the IP address of a website that uses Cloudflare.

However, if you are interested in finding out these details of a website, then we have a few easy methods for you. So, let’s see how we can trace the IP address of a website and find out its actual hosting provider.

How to find the real IP address of a website behind Cloudflare

Method 1: Tracing past records of a website

The first method includes tracing the past DNS records of a website. Old DNS records can easily tell the services used by a website’s owners in the past.

Any website that uses Cloudflare nameservers must have used the basic nameservers provided by their domain registrar or hosting provider. These nameservers can easily expose the original IP address of a website’s hosting provider.
