With the help of CloudFlare, you can easily hide your original server hosting IP address whether its Ipv4 or Ipv6. You can setup your domain with CloudFlare in just less than 5 minutes with no code changes required. They’ve around more than 100+ data centers around the world which helps your site to push and load faster.
But there is one website (
http://www.crimeflare.com/) which claims that they can easily find the original IP behind any CloudFlare service. CrimeFlare also maintains a database of IPs that appear to have been exposed.
