It says:
Iterative: The local server requests the root, TLD, and the authoritative servers for the IP address.
Isn’t it instead for the hostname?
Hi Qfl_X.
We are glad that you reached out to us. The local server sends a request (hostname) to the DNS (root, then TLD, then authoritative servers), which then returns the corresponding IP address to the local server. DNS is usually used to request the IP address against a hostname (for example, educative.io).
If you have any further questions, feel free to reach out to us.
Thank you.
