Which type of DNS server does the initial DNS query from the user's computer go to?

When a user's computer initiates a DNS query, it typically goes to a recursive DNS server, also known as a resolver. The recursive DNS server is responsible for handling the initial DNS lookup on behalf of the user's computer.
The recursive DNS server's primary function is to navigate the DNS hierarchy and obtain the requested information for the user. It starts by querying the root DNS servers, then moves on to the top-level domain (TLD) servers, and finally reaches the authoritative DNS server responsible for the specific domain.
The recursive DNS server acts as an intermediary between the user's computer and the various DNS servers involved in the resolution process. It caches the obtained DNS records to improve efficiency for subsequent requests and reduces the load on the DNS infrastructure.
By using a recursive DNS server, the user's computer offloads the responsibility of performing the complete DNS resolution process. Instead, it relies on the recursive DNS server to handle the iterative queries and provide the final DNS response.

When a user's computer initiates a DNS query, it typically goes to a DNS resolver or a recursive DNS server. The recursive DNS server is responsible for handling DNS queries on behalf of the user's computer.
Here's a simplified overview of how the process works:
1. User's computer: The user's computer sends a DNS query to the recursive DNS server. This query usually includes the domain name (e.g., www.example.com) that the user wants to access.
2. Recursive DNS server: The recursive DNS server receives the query from the user's computer. If the DNS information for the domain is not already cached, the recursive DNS server begins the process of resolving the query.
3. Iterative DNS resolution: The recursive DNS server performs iterative DNS resolution by querying different DNS servers to find the authoritative DNS server for the requested domain. It starts by querying the root DNS servers to determine the top-level domain (TLD) server responsible for the domain extension (.com, .org, etc.).
4. Authoritative DNS server: Once the recursive DNS server identifies the authoritative DNS server for the requested domain, it sends a query to that server.
5. Authoritative DNS response: The authoritative DNS server responds to the recursive DNS server with the requested DNS information, such as the IP address associated with the domain name.
6. Recursive DNS response: The recursive DNS server receives the response from the authoritative DNS server and caches the DNS information. It then sends the DNS response back to the user's computer.
7. User's computer: Finally, the user's computer receives the DNS response from the recursive DNS server, which includes the IP address associated with the domain name. The computer can then use this information to establish a connection to the desired website or service.
It's important to note that the specific DNS server configuration can vary depending on the network setup and the DNS resolver being used. However, the initial DNS query from the user's computer typically goes to a recursive DNS server for resolution.

When a user's computer initiates a DNS query, it typically starts with a recursive DNS server, also known as a resolver. The recursive DNS server is responsible for resolving the DNS query on behalf of the user's computer.
The user's computer, also known as the DNS client, sends the initial DNS query to the recursive DNS server specified in its network settings. This recursive server then takes on the task of finding the requested DNS information.
The recursive DNS server may follow a series of steps to resolve the query. It can check its local cache for a matching DNS record. If the information is not available in the cache, the recursive server may reach out to other DNS servers, starting from the root DNS servers, then the top-level domain (TLD) servers, and finally, the authoritative DNS servers responsible for the specific domain being queried. This process continues until the recursive server obtains the requested DNS information and returns it to the user's computer.
In summary, the initial DNS query from a user's computer goes to a recursive DNS server, which handles the resolution process and retrieves the requested DNS information.
