In the DNS message format, in addition to the header fields, there are 4 sections:

-questions -answer -authority -additional info.

The DNS Server, who or what populates the sections: authority and additional info?

Answer 1

• The authority section tells us what DNS servers can provide an authoritative answer to our query.
• The additional section typically includes the IP addresses of the DNS servers listed in the authority section.
