Can you explain what kind of response is provided by a DNS server?

The DNS server response is a data packet that contains information about the domain name requested by the client.

Main parts of a DNS response:

• Header: request status, flags, and other control information.
• Question: repeats the client's query.
• Answer: contains resource records (Resource Records), such as IP addresses (A or AAAA records) associated with the domain.
• Authority: information about DNS servers authoritative for the zone.
• Additional: additional data, such as IP addresses of DNS servers from the Authority section.

Example: when requesting the IP address for example.com, the response will contain an A record with the corresponding IP.

Thus, the DNS response allows the client to find out how to associate a domain name with an IP address or other information necessary for network interaction.
