Many internet service providers use their own DNS servers by default, but they may not be the most efficient. Google, Cloudflare, and OpenDNS are just a few examples of third-party DNS servers that offer faster and more reliable internet connections. But how do you determine which one is best for you?
In this article, we will guide you through the process of finding the best DNS server for your internet connection. We will explain what DNS is, why it’s important to choose the right server, and how to test and change your DNS server. Plus, we’ll discuss the benefits of using a custom DNS server and provide a list of the top DNS servers to consider. So, let’s get started and find the perfect DNS server for you!
What is DNS?
At its core, the Domain Name System (DNS) is a critical component of the internet infrastructure. Essentially, it acts as a phonebook for the internet by translating the human-readable domain names we type into our browsers into IP addresses, which are the numerical addresses that computers use to communicate with each other.
Think of DNS as a kind of directory assistance service for the internet, ensuring that users are directed to the correct location when they enter a website URL. Without DNS, we would have to memorize IP addresses for every website we wanted to visit – not the most user-friendly experience!
In a nutshell, DNS allows us to easily connect to websites by taking care of the behind-the-scenes technical details. It’s what makes browsing the internet a seamless and enjoyable experience for most people, even if they don’t realize it’s there.
The Basics of DNS
At its core, DNS is a system that translates human-readable website addresses into IP addresses that computers can understand. Here’s how it works:
When you enter a website address (e.g. www.example.com) into your web browser, it sends a request to a DNS resolver, which is typically provided by your Internet Service Provider (ISP) or a third-party DNS provider.
The resolver then contacts a DNS root server to determine the authoritative nameserver for the top-level domain (TLD) of the website address (e.g. .com).
The resolver then contacts the authoritative nameserver for the TLD to determine the authoritative nameserver for the second-level domain (SLD) of the website address (e.g. example.com).
This process continues until the resolver receives the IP address associated with the website address you entered. Once the IP address is obtained, your web browser can connect to the website’s server and retrieve the website’s content.
DNS servers are responsible for storing and distributing this mapping information, making it possible for us to use the internet without having to memorize the IP addresses of every website we want to visit.
There are two main types of DNS servers: recursive and authoritative. Recursive DNS servers are responsible for resolving queries on behalf of clients, while authoritative DNS servers are responsible for providing answers to queries about a specific domain name. These two types of servers work together to make the internet function smoothly and efficiently.
How DNS Works
DNS Resolvers: When you enter a website’s address in your browser, your device sends a request to a DNS resolver. The resolver then queries the DNS server to find the IP address associated with the website’s domain name.
DNS Servers: DNS servers are responsible for storing and maintaining records of domain names and their corresponding IP addresses. When a DNS resolver queries a DNS server, it responds with the IP address associated with the domain name requested.
Name Resolution Process: The name resolution process involves a series of steps that occur when a device sends a request to access a website. This process involves multiple DNS resolvers and servers communicating with each other until the correct IP address is found and returned to the requesting device.
Caching: To speed up the name resolution process, DNS resolvers and servers often cache the results of previous queries. This means that if a domain name has been requested recently, the resolver or server can simply return the cached IP address instead of querying other servers, making the process faster.
Common DNS Terminology
- IP Address: Internet Protocol Address, a unique numerical identifier assigned to each device connected to the internet.
- Name Server: A server that translates domain names into IP addresses, also known as a DNS server.
- TLD: Top-Level Domain, the highest level of domain names in the DNS hierarchy, such as .com, .org, or .net.
Understanding common DNS terminology is important when trying to find the best DNS server for your internet connection. Knowing the difference between an IP address and a name server can help you troubleshoot connection issues, while understanding TLDs can help you choose a more secure domain name for your website.
When it comes to choosing the right DNS server, it’s also important to consider factors such as reliability, speed, and security. This is where understanding common DNS terminology can be especially helpful.
By familiarizing yourself with the basics of DNS and common terminology, you’ll be better equipped to make informed decisions when it comes to choosing a DNS server that best meets your needs.
Why is Choosing the Right DNS Server Important?
Performance: The DNS server you use can have a big impact on the speed and reliability of your internet connection. A slow or unreliable DNS server can lead to longer load times, increased buffering, and other frustrating issues.
Security: Using the wrong DNS server can also put your online security at risk. Some DNS servers may be more vulnerable to attacks, or may not have the necessary security features to protect against threats like phishing scams.
Content Access: The DNS server you use can also impact what content you’re able to access online. Some DNS servers may restrict access to certain websites or services, while others may be optimized for specific types of content.
Privacy: Finally, the DNS server you use can impact your online privacy. Some DNS servers may track your browsing activity or sell your data to third-party advertisers, while others may be more privacy-focused.
Impact on Internet Speed
One of the main reasons why choosing the right DNS server is important is its impact on internet speed. DNS servers play a crucial role in the speed at which websites load on your device, as they act as a directory that translates domain names into IP addresses. When you enter a website URL into your browser, your device sends a request to the DNS server to retrieve the IP address associated with that domain name. If the DNS server is slow or inefficient, it can cause delays in loading websites or even result in connection timeouts.
By selecting a fast and reliable DNS server, you can significantly improve your internet speed and browsing experience. Some DNS servers have advanced caching algorithms that can further speed up the process of resolving domain names. Additionally, using a DNS server that is closer to your physical location can also reduce latency and improve internet speed.
However, keep in mind that there are other factors that can affect your internet speed, such as your internet service provider (ISP), network congestion, and the quality of your router. Nevertheless, choosing the right DNS server is an essential step in optimizing your internet speed and reducing frustrating delays when browsing the web.
How to Test Your Current DNS Server?
If you want to determine your current DNS server, there are several ways to do so. One way is to use the command prompt on your computer and enter the ipconfig /all command. This will display information about your network adapter, including the DNS servers being used.
