    Thank you for such a great content @PowerCert Animated Videos. Can you pls tell if there are many such domain names which requires this complete process, I mean, almost all domain names would be cached by resolver/ISP ? ISP are airtel, jio and all..right ?? And how much time this complete process require.

    sorry, didn't get it. if the authoritative name server is final authority then why not sent query directly to it rather than root and TLD servers?
