Cloudflare is a company providing content delivery Network (CDN), DNS, DDoS protection and security services. They are known for their fast DNS lookup time in the network performance industry and have a powerful network of more than 100 different data centers around the world. They are supported by industry celebrities such as Google, Microsoft and Qualcomm. Some of their customers include NASDAQ, Digital Ocean, Zendesk and Cisco.
if you are looking for an easy way to speed up and enhance the security of WordPress sites, Cloudflare is a good solution. Most customers can even use their free plan, which provides unlimited CDN bandwidth. Follow these steps to install Cloudflare on your WordPress website.
Note: if you use Cloudflare, you cannot use the advanced DNS from Amazon Route 53. Cloudflare runs as a full proxy service, which means that you must select one of them. If you want to use our advanced DNS, you can use an alternative CDN to speed up your website, such as KeyCDN, which is not a complete agent.

Cloudflare gives you two options. You can use their CDN and protection (to accelerate and protect your site), or you can simply use their DNS. Most customers will want the former because this is where you will benefit from everything Cloudflare has to offer. To make sure your domain is enabled, make sure the cloud is lit in orange. If you have other records, such as email (MX records), these records should be turned off Cloudflare (grayed out). Click continue when you are finished verifying everything. You can modify these records at any time in the future.

step 4
then, you need to change the name servers on the domain to point to Cloudflare (using the names they provide). Because Cloudflare is a complete proxy service, basically it works by pointing your domain to Cloudflare, and then Cloudflare pointing your domain to the server address. There is no downtime when switching name servers. Here are several documentation links to different domain name registrars on how to change them. How
uses Namecheap to change the name server
uses GoDaddy to change the domain name server
uses Google Domains to change the domain name server
- uses Bluehost to change the name server
- and then click “Continue”. It should not take long for

- , but it will take up to 24 hours to process the change.
step 5
if your site does not already point to the server, you need to update the A record to point to the server IP in the Cloudflare dashboard. Click “DNS” and next to the A name record, change it to the IPv4 address of your server.

that’s it! Your WordPress website now has Cloudflare installed.
