Hi,
My domain is with Godaddy and they have two DNS details by default.
Since I wanted to host it with 1and1.com, I changed the DNS with 1and1 DNS details and it is working fine.
Now, I want to use the Cloudflare and need to change my DNS details with my registrar 
So, the problem is, If I change the DNS to cloudflare, will Godaddy domain will know where it is hosted?
Thank you.
Depends on whether you proxy your site through Cloudflare (
) or not (
) but why would that be a problem in the first place? Apart from using Godaddy as registrar 
Thank you for your reply
If I change the DNS details with cloudflare. Won’t godaddy forget where the site is hosted
What do you mean by “forget”? Your nameservers are currently not with them as far as I understand, right?
If you switch to Cloudflare you need to make sure the DNS records are correctly imported, or otherwise set them to the correct values.
