Purpose of making:
Almost every person that has an electronic device is somehow connected to the internet. Each device that is connected to the internet has a unique numeric identifier, called an IP address.
The computers easily understand the numeric address (IP address), but it’s difficult for humans to memorize those numeric addresses. And without those accurate numeric addresses, you cannot land at the correct destination on the internet.
Therefore, for humans, the domain/hostname is there. Each domain/hostname on the internet has a unique IP address, and the Domain Name System routes the user entered domain name to its correct IP address.
When the user sends a request from its browser, that request is sent to the DNS database. The database looks up its DNS records, finds its IP address, and sends that request to the particular server.
When a web admin makes any changes in its DNS records, it takes time to propagate globally. Each DNS server has its TTL. Therefore, the DNS records take 24 to 48 hours to propagate fully.
The purpose of making the DNSChecker is to check that either the DNS records are propagated fully or not.
