CloudFlare is a content delivery network and distributed domain name server service marketed as improving website performance and speed and providing security. the primary reasons i love it is, it has feature-rich free service and protection against DDoS attack.
After moving this blog to a new host, it was necessary I update the domain nameserver to point to the new host. mind you the domain is hosted at CloudFlare which in turn is pointing to my web host IP address.
I didn’t want to take the risk of deleting and re-adding my website to CloudFlare as I will lose my personalize configuration settings.
If you had a change of host, no need altering your domain name server provided by cloudflare (xxx.ns.cloudflare.com), or deleting and re-adding your website. all you should do is, on your CloudFlare DNS Zone File page, change every “A” record’s IP address of your old host to your new host IP address as shown in the image below.
To get your new web host IP address, check the sidebar of your cPanel manager.
Alternatively, use a DNS lookup tool like magic-net.info or DNSstuff to get your web host IP.
Allow time for the DNS changes to propagate and your site will be up and running.
