In this article, we’ll guide you through a step-by-step process to help you discover your DNS server IP address using Command Prompt, and show you how to troubleshoot any DNS server issues you may encounter.
By the end of this article, you’ll have a better understanding of DNS servers, why you need to know your DNS server IP address, and how to troubleshoot DNS server issues. Let’s dive in!
What is a DNS Server?
Every time you type a web address into your browser, your computer sends a request to a DNS server to translate the domain name into an IP address that can be used to locate the server that hosts the website. DNS stands for Domain Name System, and it is a crucial component of the internet infrastructure. It acts as a kind of phone book for the internet, mapping domain names to IP addresses.
When you type a web address into your browser, your computer contacts a DNS resolver, which in turn sends a query to one or more DNS servers to find the correct IP address. The DNS server responds with the IP address, and the resolver sends this information back to your computer. Once your computer has the IP address, it can connect to the web server and request the website content.
The process of finding the correct IP address can take a fraction of a second, but it is crucial to the functioning of the internet. Without DNS servers, we would have to memorize the IP addresses of all the websites we wanted to visit, which would be impossible given the sheer number of websites on the internet.
In summary, a DNS server is a critical component of the internet infrastructure that maps domain names to IP addresses, allowing computers to locate web servers and retrieve website content.
Definition of a DNS Server
| Term | Definition | Function |
|---|---|---|
| DNS | DNS stands for Domain Name System, which is a hierarchical and decentralized naming system for computers, services, or other resources connected to the Internet or a private network. | The main function of a DNS server is to translate human-readable domain names into IP addresses that machines can understand. |
| IP Address | An IP address is a unique numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. | When a device requests a website by its domain name, the DNS server translates it into the corresponding IP address. |
| Root Server | The root server is the first step in translating human-readable domain names into IP addresses. It contains a list of authoritative DNS servers for all top-level domains. | When a DNS server cannot find the IP address for a given domain name, it will query the root server for the authoritative DNS server for that domain. |
| TLD | TLD stands for top-level domain, which is the last part of a domain name, such as .com, .org, .edu, etc. | Each TLD has a set of authoritative DNS servers that contain information about the domain names registered under that TLD. |
| Recursive Query | A recursive query is a DNS query in which the DNS server is expected to fully resolve the query and return the IP address to the requesting device. | When a device requests a website by its domain name, its local DNS server will typically perform a recursive query to resolve the domain name and return the IP address. |
In summary, a DNS server is a critical component of the Internet infrastructure that translates human-readable domain names into machine-readable IP addresses. By using a hierarchical and decentralized system of authoritative DNS servers, DNS servers can quickly and efficiently resolve domain names into IP addresses. Understanding how DNS servers work is essential for anyone who wants to optimize their network performance or troubleshoot network issues.
How a DNS Server Works?
Domain name system (DNS) works on the principle of mapping the domain name to an IP address. When a user enters a domain name in the browser, the browser sends a request to the DNS server to translate the domain name to its IP address. The DNS server then responds with the corresponding IP address.
DNS servers work on a hierarchical system where each DNS server caches the IP addresses of the recently accessed domain names. When a DNS server receives a request for a domain name, it first looks into its cache to find the IP address. If the IP address is not present in the cache, it forwards the request to the next DNS server in the hierarchy.
DNS resolution happens in two ways – recursive and iterative. In the recursive method, the DNS server sends a request to the root DNS server, which then recursively searches through the DNS hierarchy until it finds the IP address. In iterative resolution, the DNS server starts from the top-level domain and works its way down to the domain name in question.
The DNS server essentially acts as the phone book of the internet, translating domain names into IP addresses that computers can understand. Understanding how it works is essential for troubleshooting DNS issues and optimizing network performance.
