Understanding what happens during the propagation period of 3 to 4 day.


When you change your domain DNS settings in your domain registrar control panel, the new settings must be propagated to all DNS servers around the world. It also implies that each ISP (Internet Service Provider) must update their DNS records to reflect these new changes, which is usually done automatically every 24 hours, but not always.

Note: This DNS propagation is only applied to DNS manager without proxy enabled.
For instance, if the DNS manager is pointing to cloudflare and the DNS record has proxy setting enabled, then you will never know what is actual DNS records unless if you have access to the specific cloudflare account.

This is because proxy setting acts as IP address masking so that people would not know the actual IP address of a domain for security reasons.
