Numerical Identifier: Like a physical street address, the IP address provides a specific location for the DNS server on the network.
Communication Facilitator: Your computer uses this address to send requests to the DNS server, asking it to resolve a domain name into an IP address.
Translation Service: The DNS server then translates the human-readable domain name into a machine-readable IP address, enabling your browser to connect to the correct web server.

2. How Does a DNS Server IP Address Work?

The DNS resolution process involves a series of steps to translate a domain name into an IP address. Understanding these steps clarifies the importance of a DNS server IP address.

DNS Query: When you type a domain name into your browser, your computer sends a DNS query to the configured DNS server IP address.
Recursive Query: If the DNS server doesn’t have the IP address in its cache, it performs a recursive query, contacting other DNS servers to find the correct IP address.
Authoritative Server: The query eventually reaches the authoritative name server for the domain, which holds the correct IP address.
IP Address Retrieval: The authoritative server returns the IP address to the DNS server, which then sends it back to your computer.
Web Server Connection: Your computer uses the IP address to connect directly to the web server hosting the website.
