In today’s digital age, protecting online privacy has become essential. Virtual Private Networks (VPNs) and encrypted DNS (Domain Name System) are two widely used methods for improving internet security. While both play important roles in protecting user data, they perform different functions and work in distinct ways. Understanding the differences between VPN and encrypted DNS might help you select the best tool for your needs. We are here to help, so do not worry. Today, we will go over the meanings of all of these and more, and we will provide you all of the information you need to decide which of these useful browsing tools is best for you.

What Is a VPN?

A VPN (Virtual Private Network) improves internet security and privacy by utilizing encryption and dedicated servers. The best secure connection is one that connects two computers over a single wire and prevents third parties from intercepting the data. A solid VPN will get you as near to that level of secrecy. VPNs can also let you avoid restrictions such as DNS and IP filters, allowing you to access previously restricted content. It encrypts your internet traffic and masks your IP address and DNS, making it impossible to track your online activity. You should consider using a VPN for greater online freedom and data security.

Key Features of a VPN:

• IP Address Masking: Masks your true IP address to increase anonymity.
• Encryption: All internet communication between your device and the VPN server is encrypted to prevent it from being intercepted by hackers, ISPs, or governments.
• Location Spoofing: Allows you to access geo-restricted content by changing your virtual location.
• Full Network Protection: Encrypts all traffic on your device, including DNS queries.

VPNs are great for anyone who wants complete privacy and protection, particularly when utilizing public Wi-Fi or accessing restricted content.

What Is Encrypted DNS?

DNS stands for Domain Name System. A domain name is what you type into your browser to access a website, such as verycutecats.com. However, the Internet does not ‘operate’ on domain names; rather, it works on numerical addresses, which are unique identifiers for each device connected to the Internet. When you type ‘verycutecats.com’ into your browser, your computer must translate the address into a computer-friendly format so that you can see the cats.

To accomplish this, your request is routed through a DNS resolver. Whether you realize it or not, you always utilize a DNS resolver anytime you access a website or web service that uses HTTP/s. Typically, your ISP (internet service provider, but you already knew that!) will automatically configure you with their default DNS server. People in the know, on the other hand, like to make their own choices.

You may configure your DNS resolver for your desktop or mobile device through your operating system or directly in the browser. Some popular standard DNS resolvers include Cloudflare (1.1.1.1) and Google (8.8.8.8). Because more intricate sites frequently require many DNS lookups before loading, your devices are most likely generating hundreds or thousands of these queries per day – and speed is important when doing anything that frequently.

Encrypted DNS traffic secures DNS requests by employing encryption methods during DNS resolution, which converts domain names (such as nordvpn.com) into IP addresses (such as 192.0.2.1). DNS communication is usually not encrypted, so anyone with network access (such as your internet service provider or hackers) can view the DNS requests. Encrypting DNS traffic protects DNS queries and responses from third parties attempting to spy on your online behavior.

Different methods of DNS encryption

There are three forms of DNS protection: DNS over HTTPS (DoH), DNS over TLS (DoT), and DNSCrypt. Here’s a thorough description of what each one accomplishes.

DNS over HTTPS (DoH)

DNS over HTTPS (DoH) sends DNS data via an HTTPS connection on port 443 using the user datagram protocol to handle rapid and lightweight requests. HTTPS is the standard protocol for most websites. If your encrypted DNS communication is HTTPS-secured, anyone who intercepts it will only receive the encrypted version, not the plaintext DNS request itself. It also employs the user datagram protocol to handle.

DNS over TLS (DoT)

DNS over TLS (DoT) is an additional encryption mechanism for DNS traffic. In this example, data is encrypted and transmitted via the Transport Layer Security protocol over port 853. DNS communication, like DoH, benefits from end-to-end encryption while in transit. While DoH sends encrypted DNS communication to and from the same port as all HTTPS traffic, DoT data is routed through a different port. As a result, it is easy to troubleshoot DoT and identify potential protocol issues.

DNSCrypt

DNSCrypt is a protocol that lets you profit from encrypted DNS traffic. It employs end-to-end encryption, similar to DoH and DoT, but its differentiating feature is its ability to thwart DNS spoofing attacks. The protocol authenticates traffic to ensure that it has not been tampered with and originates from the correct DNS resolver.

What is a ‘Smart’ DNS?

SmartDNS is a sophisticated DNS technology that enables users to access content that would otherwise be unavailable on their devices. When you enter an address to visit a website or service, SmartDNS redirects specific DNS requests based on the predefined area. SmartDNS makes it appear as if you are visiting the website from that location.

You may access the material you desire from anywhere, including internationally. However, SmartDNS, unlike a VPN, focuses on content access rather than online security and privacy capabilities. SmartDNS does not give you a new IP address; it only alters how a website perceives your IP address. Users can purchase SmartDNS services separately or as part of a larger package, such as a VPN.  Some VPNs like Enova VPN provide SmartDNS services, which allow you to swiftly and securely access your favorite content. You may configure SmartDNS on your TV and other devices.

More About Encrypted DNS

Your devices are most likely to use your ISP’s DNS resolver. DNS queries are plaintext records of the websites you visit, and ISPs frequently retain them together with your IP address. With custom DNS, you can switch from your ISP’s DNS servers to one of your own choosing. Google, Cloudflare, and other companies provide public DNS services.

This prevents your ISP from automatically logging your DNS requests, but it does not mask your IP address, encrypt your traffic, or unblock geo-restricted streaming services. However, changing your DNS server does not totally prevent your ISP from monitoring your internet activities. Your DNS requests will still pass through your ISP’s network equipment, making them vulnerable to packet sniffing if unencrypted.
