What is Cloudflare CDN?

Cloudflare is a Content Delivery Network (CDN) that acts as a proxy between a website and the visitor. This system enables users to receive cached static content from the nearest servers. With less physical distance, the site can load faster.

What’s great about Cloudflare is that it has one of the biggest server networks in the world. As such, no matter where your visitors are, Cloudflare will help you deliver the fastest website experience. This will also help improve your site’s SEO as speed is one of the ranking factors in search engines.

Compared to traditional CDN, Cloudflare offers many other useful features:

  • DDoS attack mitigation
  • Analytics on all requests made to a website
  • Easy SSL certificate installation
  • Network gateway between protocols

Step 3: Checking the DNS Records of Your Domain Name in Cloudflare

Once your WordPress site is added to Cloudflare, you’ll be prompted with the DNS details of your domain name. In this step, you can enable or disable Cloudflare for specific subdomains.

We highly suggest that you enable Cloudflare for your naked domain name and www subdomain. This way, Cloudflare will work on both www and non-www versions of your site.

Once you are done, press the Continue button to proceed to the next step.

It’s not recommended to enable CloudFlare for cPanel, mail, FTP, or any other subdomains as it can result in various DNS issues.

Step 4: Pointing Your Domain Name to Cloudflare Nameservers

After activating Cloudflare for your domain and subdomains, you will be greeted with the Cloudflare nameservers on the next page. Now, we need to replace your old nameservers with Cloudflare’s.

  1. Open a new browser tab and visit your hosting control panel. If you’re a Hostinger user, you can find the details of your nameservers in the Domains tab.

Alternatively, you can also check the update status on the Cloudflare website. During this process, your page will not face any downtime.
