Extract Real IP Address Of Server Behind Cloudflare

CloudFlare is one of the most popular and fastest growing Content Delivery Network (CDN) providers including load balancers, DDoS protection and so on. The best known service is the distributed domain name server that, among other things, acting like a reverse proxy hides the real location of a website. However, if not properly configured, any web service could accidentally leak the real IP in a number of ways.

There is no way in DNS lookup you will get the actual IP where your website is hosted. This is good in one way that CloudFlare protects it.

However, if you are doing some research to find out actual IP then it becomes difficult. But not to worry anymore, lately, I found an online tool, which actually reveal real IP address.

DNS Trails is one such website that seems to be fairly accurate in regards to the historical information that it maintains.

Censys search engine allows researcher to find how websites are deployed with possible to reveal the IP address as well.

Send An Email

Simply Sign Up an account on website and you might get confirmation email with header containing ip address of original server behind cloudflare if the origin server not using any third services.

So now you know how to find the IP address of the website which is behind CloudFlare.

Once the real IP address of the web server is known, any protection that Cloudflare offers is lost. The web application firewall is skipped entirely along with any HTTPS rewrites or DDoS protection.

Do you know other ways to get bypass and get origin IP address behind Cloudflare?
