What is a DNS server?

A DNS server is a crucial component of the internet’s infrastructure. In simple terms, it acts as a translator between human-friendly domain names like “” and the corresponding IP address like “”. Without a DNS server, it would be nearly impossible for humans to remember and access all the IP addresses associated with various websites.

When you enter a domain name into your web browser, it sends a request to the DNS server to resolve the domain name to an IP address. The DNS server then responds with the appropriate IP address, allowing your browser to establish a connection to the website.

There are several types of DNS servers, including recursive, authoritative, and caching. Recursive servers are responsible for handling requests from end-users, while authoritative servers store the official records for specific domain names. Caching servers store recently accessed records, allowing for faster lookup times.

Overall, DNS servers are a fundamental part of how the internet works, and without them, we wouldn’t be able to access the vast amount of information and resources available on the web.

Definition of DNS server

DNSThe Domain Name System is a hierarchical and decentralized naming system for computers, services, or other resources connected to the Internet or a private network.When you enter a website URL like, DNS translates the URL to an IP address like, allowing your browser to connect to the correct server.
DNS serverA DNS server is a specialized computer that manages the translation of domain names to IP addresses, making it possible for devices to communicate with each other on the internet.When you connect to a website, your computer queries a DNS server to translate the domain name to an IP address.
ResolverA resolver is a component of the DNS that resides on a client machine and receives DNS queries from the client’s application.When you type a website URL into your browser, the resolver on your computer sends a query to a DNS server to translate the domain name to an IP address.
Root serverThe root servers are a critical part of the DNS infrastructure that store and manage the top-level domain (TLD) name servers.There are 13 root servers located around the world that contain information about TLD name servers for top-level domains like .com, .org, and .net.
TLDThe top-level domain is the last part of a domain name, such as .com, .org, .net, or .gov.Domain names are organized into a hierarchy, with TLDs at the top and subdomains beneath them.

Understanding the basics of DNS servers is crucial for troubleshooting DNS issues, which can cause problems with internet connectivity and accessing websites. Keep reading to learn more about common DNS problems and how to fix them.

How does a DNS server work?

A DNS server acts as a directory for the internet, translating domain names into IP addresses. When you enter a URL into your browser, your computer sends a request to the DNS server, asking for the IP address of the website’s server.

The DNS server then checks its database to see if it has the IP address for the domain name. If it does, the DNS server sends the IP address back to your computer. If it doesn’t, the DNS server sends the request to other DNS servers until it finds the IP address.

Once your computer has the IP address, it can connect to the website’s server and download the webpage. This process happens in a matter of seconds, allowing you to access the internet quickly and easily.

Importance of DNS server in internet connectivity

Internet connectivity is an essential part of our daily lives, and the DNS server plays a crucial role in ensuring that we stay connected. Without it, browsing the internet would be a cumbersome task.

The DNS server is responsible for converting the domain name entered into the web browser into an IP address that is required for the browser to access the website. It works as a translator between the human-readable domain name and the machine-readable IP address.

Without the DNS server, we would have to remember and enter the IP address of each website we want to access. The DNS server simplifies the process and makes it easier for us to navigate the internet.

In addition, the DNS server also helps to ensure that our internet connection is secure by blocking access to malicious websites and redirecting us to safe ones. This added layer of security is crucial in protecting us from cyber threats.

Why is my DNS server not responding?

Incorrect DNS server address: If the DNS server address is not correct or has been changed, it can cause connectivity issues. You may need to update the DNS server address in your network settings.

Firewall blocking DNS server: If your firewall settings are blocking the DNS server, it may cause issues with connectivity. You can try temporarily disabling the firewall to see if it resolves the issue.

Malware or virus: Malware or viruses on your device can also cause DNS server issues. Running a full system scan with an antivirus software can help identify and remove any malicious programs causing the issue.

Common causes of DNS server issues

DNS server outage: A DNS server outage can occur due to a variety of reasons such as maintenance, hardware failure, or even a cyberattack. This can result in a complete loss of internet connectivity.
