What is a DNS server and how does it work?
DNS server stands for Domain Name System server, and it is a critical component of the internet’s infrastructure. Put simply, a DNS server acts as a kind of translator between human-readable domain names, like google.com, and the IP addresses that computers use to communicate with one another.
When you type a website’s URL into your browser, your device sends a request to the DNS server, which looks up the corresponding IP address and sends it back to your device. This enables your device to connect to the website’s server and load its content.
Without DNS servers, we would need to remember the IP addresses of every website we want to visit, which would be a challenging task given the internet’s size and scale.
The Basic Functionality of a DNS Server
A DNS server is responsible for translating website names into their corresponding IP addresses, which enables your computer to access the website you are looking for. When you enter a website URL into your web browser, the DNS server is the first point of contact your computer makes in order to locate and load the website.
The process of how a DNS server works involves a hierarchical system of servers that work together to translate the domain name into an IP address. When you enter a URL into your browser, your computer contacts a local DNS server, which checks its own cache and forwards the request to other DNS servers until the IP address is found.
In addition to providing the IP address, the DNS server also provides other information that your computer needs to establish a connection with the website, including the domain’s mail server and other information related to the website’s configuration.
Types of DNS Servers Explained
There are four types of DNS servers:
- Recursive DNS Servers: These servers help users connect to any website by finding and returning the IP address of the requested domain name. They are typically operated by Internet Service Providers (ISPs).
- Root DNS Servers: These servers are the first stop in the DNS lookup process. They maintain a directory of all top-level domain (TLD) names and their corresponding IP addresses.
- TLD DNS Servers: These servers are responsible for maintaining information about the specific TLDs they serve. For example, .com or .org.
- Authoritative DNS Servers: These servers are responsible for maintaining the DNS records for a specific domain name. They provide the IP address of the domain name when requested by a recursive DNS server.
Each of these DNS server types play an important role in the functioning of the internet. The recursive DNS servers make the web accessible by returning the IP address of a website when a user types in a domain name. Root DNS servers maintain a directory of TLD names and their corresponding IP addresses, while TLD DNS servers are responsible for specific TLDs. Authoritative DNS servers maintain DNS records for a specific domain name.
Understanding the different types of DNS servers can help you troubleshoot connectivity issues and optimize your internet connection for faster speeds and better performance.
How DNS Resolving Process Works?
DNS resolution is the process of converting domain names into IP addresses so that computers can communicate with each other on the internet. The DNS resolving process involves a series of steps:
Step 1: Requesting the DNS Server – When a user enters a domain name in a web browser, the computer sends a request to the configured DNS server to resolve the domain name into an IP address.
Step 2: Querying the Root Server – If the DNS server doesn’t have the IP address for the requested domain name in its cache memory, it sends a query to the root server to determine the authoritative DNS server for the top-level domain of the domain name.
Step 3: Querying the Authoritative DNS Server – The root server returns the IP address of the authoritative DNS server for the top-level domain, and the DNS server sends a query to this authoritative DNS server to resolve the domain name into an IP address.
Step 4: Resolving the Domain Name – The authoritative DNS server responds with the IP address of the domain name, and the DNS server returns this IP address to the user’s computer. The computer can then use this IP address to communicate with the server that hosts the website or service associated with the domain name.
The DNS resolving process typically takes only a few milliseconds to complete, but delays can occur if the DNS server is slow or if the requested domain name is not cached and needs to be resolved by querying multiple DNS servers. Understanding how the DNS resolving process works can help you troubleshoot issues related to slow or unreliable internet connectivity and make informed decisions when choosing the best DNS server for your needs.
How to determine if your current DNS server is not working for you
If you are experiencing slow internet speed or if you are having trouble accessing certain websites, it might be time to check if your current DNS server is working properly. One way to determine if your DNS server is the culprit is to try accessing the website using its IP address instead of its domain name.
Another sign that your DNS server is not working properly is if you are getting error messages such as “server not found” or “DNS server not responding”. If you encounter these errors frequently, it may be time to switch to a more reliable DNS server.
You can also use online tools to test your DNS server’s performance. These tools will give you insights into your DNS server’s response time and help you determine if it is causing any delays or performance issues.
Common Symptoms of a Faulty DNS Server
- Slow Internet Speed: A slow internet connection can be caused by an overburdened or underperforming DNS server. If your internet speed is slower than usual, it may be worth checking your DNS server.
- Website Not Loading: If you’re having trouble accessing a specific website, it may be a problem with your DNS server. This is especially likely if you can access other sites with no issue.
- Intermittent Connectivity: If your internet connection is working inconsistently, with some websites or applications working fine while others don’t, it could be due to a faulty DNS server.
- Connection Timeouts: If you’re experiencing frequent connection timeouts or inability to connect to certain websites, it’s likely that your DNS server is causing the issue.
If you’re experiencing any of these issues, it may be worth investigating your DNS server to see if it is causing the problem. In the next section, we’ll go over some methods you can use to test your DNS server and diagnose any issues.

Tips for optimizing your DNS server for maximum speed and security
DNS Cache: DNS caching can significantly increase the speed of your DNS requests. When you request a website, the DNS server typically has to look up the IP address associated with that website. If the IP address is not already stored in the cache, the server has to make a new request to find it. By caching frequently used IP addresses, your computer can quickly retrieve them without needing to make a new request each time.
Use a secure DNS: By using a secure DNS service, you can protect your privacy and security online. Secure DNS services use encryption to prevent eavesdropping and phishing attacks, as well as blocking access to known malicious websites. Some popular secure DNS services include Cloudflare DNS, Quad9, and DNS.WATCH.
Limit the number of DNS servers: Having too many DNS servers configured on your device can lead to slow response times and potential security issues. It’s recommended to have no more than two DNS servers configured at any given time.
Regularly update your DNS server: DNS servers can become outdated over time, which can result in slow performance and potential security vulnerabilities. Regularly updating your DNS server can ensure that it’s functioning optimally and that any known security vulnerabilities have been addressed.
Use a reliable DNS server: Choosing a reliable DNS server can ensure that you’re always connected to the internet and that your DNS requests are processed quickly. Popular DNS servers include Google Public DNS, OpenDNS, and Cloudflare DNS, among others.
Use Secondary DNS Server for Maximum Availability
One of the best practices for optimizing your DNS server is to use a secondary DNS server. Having a secondary DNS server helps in maximizing availability of your website or application by providing a backup DNS server in case the primary server fails.
Configuring a secondary DNS server is easy, and it involves adding the IP address of the secondary server to the list of DNS servers in your network settings.
It’s important to choose a secondary DNS server that is reliable and located in a different geographic region from your primary server. This will help in reducing the risk of downtime caused by natural disasters, network failures, or other issues that can affect the primary server.
Securing DNS Queries with DNSSEC
DNS Security Extensions (DNSSEC) is a technology that adds a layer of security to the Domain Name System (DNS) protocol by digitally signing DNS records. This ensures that the information received from DNS servers is authentic and has not been tampered with.
With DNSSEC, it is possible to prevent DNS spoofing attacks, cache poisoning, and other DNS-related security threats. DNSSEC works by providing a way to validate the authenticity of DNS records by digitally signing them using public-key cryptography.
To implement DNSSEC, you need to generate and publish a public key for your domain name, and then sign your DNS records with a private key. This ensures that anyone querying your DNS server receives authentic and trustworthy information. DNSSEC can be configured for your domain by your domain registrar or DNS hosting provider.
Enabling DNSSEC provides an additional layer of security to your DNS infrastructure, making it harder for attackers to compromise the integrity of your DNS records. It is highly recommended for organizations that require high levels of security for their DNS infrastructure.
