Cloudflare provides DDoS mitigation, internet security services in between website visitors and the server on which content is being hosted. At the moment Cloudflare is one of the most popular free CDN service providers.
To use the services, registration has to be done on Cloudflare system. This can be done via following link:

Select Suitable Cloudflare service plan (Free is also suitable). Proceed with current DNS record scan, by pressing “Continue” button.
2. DNS change
Set the nameservers that you will receive, in this example it was dane.ns.cloudflare.com and tegan.ns.cloudflare.com, however it is very likely that for your domain it will be different. This change has to be done from your domain registry (company on which you have registered your domain). Usage of both Nameservers are mandatory. The change will be fully saved after TTL of the DNS servers will pass.
After the change you will have to wait until it will be completed. Cloudflare system will automatically refresh the information of changes. Manual check initiation is also possible by pressing “Recheck Nameservers” button. If you have closed domain management panel it can be re-opened again by selection “Overview” menu option and choosing the domain.
