VPN and Encrypted DNS: Key Differences Explained

Protecting your privacy online has become essential, and VPNs and encrypted DNS are two of the most widely used ways to do it. Both matter, but they do different jobs and work in different ways. Once you understand where they diverge, choosing between them — or deciding to use both — becomes straightforward.

What is a VPN?

A VPN, or Virtual Private Network, improves your security and privacy using encryption and dedicated servers. The most secure connection imaginable would be two computers joined by a single private wire that no one else can tap; a good VPN gets you remarkably close to that. It encrypts your internet traffic and masks both your IP address and your DNS queries, which makes your activity far harder to trace. It also lets you get past DNS and IP-based filters, opening up content that would otherwise be unavailable.

Key features of a VPN

• IP address masking: hides your real IP address to increase anonymity.
• Encryption: everything travelling between your device and the VPN server is encrypted, so it cannot be read by attackers, ISPs or governments.
• Location switching: change your apparent location to reach geo-restricted content.
• Whole-device protection: encrypts all traffic from your device, DNS queries included.

A VPN suits anyone who wants comprehensive privacy, particularly on public Wi-Fi or when reaching restricted content.

What is encrypted DNS?

DNS stands for Domain Name System. A domain name is what you type into your browser to reach a site. The internet, however, does not run on names — it runs on numeric addresses that uniquely identify each connected device. So when you type a domain, your computer has to translate it into that machine-readable form first.

That translation happens through a DNS resolver. You use one every time you open a website, whether you notice it or not. Your ISP normally assigns you their own resolver by default, though you are free to choose another.

You can set your resolver at the operating-system level or directly in the browser. Well-known public options include Cloudflare (1.1.1.1) and Google (8.8.8.8). Because a complex page often needs many lookups before it finishes loading, your devices are probably making hundreds or thousands of these queries a day — so speed matters.

Encrypted DNS secures those requests as they are resolved, turning a domain name into an IP address without exposing it. DNS traffic is normally sent in the clear, which means anyone with access to the network — your ISP, or an attacker — can read exactly which sites you are looking up. Encrypting it keeps those queries and their responses away from anyone trying to watch what you do.

Methods of DNS encryption

There are three main approaches: DNS over HTTPS, DNS over TLS, and DNSCrypt.

DNS over HTTPS (DoH)

DoH sends DNS data over an HTTPS connection on port 443 — the same protocol and port ordinary web traffic uses. Anyone intercepting it sees only the encrypted version, never the plaintext request. Because it is indistinguishable from normal HTTPS traffic, it is also difficult to block selectively.

DNS over TLS (DoT)

DoT encrypts DNS traffic using the Transport Layer Security protocol over port 853. Like DoH, it protects queries end to end while in transit. The difference is the port: DoT uses a dedicated one rather than blending in with web traffic, which makes it easier to troubleshoot and to monitor on a network — but also easier to block.

DNSCrypt

DNSCrypt also encrypts DNS traffic end to end, but its distinguishing feature is protection against DNS spoofing. It authenticates the traffic to confirm it has not been tampered with and genuinely came from the resolver you expected.

What is SmartDNS?

SmartDNS is a technique for reaching content that would otherwise be unavailable on your device. When you request a site, it redirects particular DNS queries through a chosen region, making it appear you are visiting from there.

That gets you the content you want from almost anywhere — but SmartDNS is about access, not security. It does not give you a new IP address; it only changes how a website perceives your location, and it does not encrypt anything. It is sold separately or bundled with a VPN. EnovaVPN includes SmartDNS, so you can reach your usual content quickly and still be protected, and it can be configured on a TV as well as on phones and computers.

DNS versus SmartDNS

• Standard DNS translates domain names into IP addresses; SmartDNS additionally reroutes selected lookups through another region.
• Standard DNS does not change what content you can reach; SmartDNS is built specifically to unlock region-locked content.
• Neither encrypts your traffic or hides your IP address on its own.

More about encrypted DNS

By default your devices almost certainly use your ISP's resolver. DNS queries are a plaintext record of every site you visit, and ISPs frequently retain them alongside your IP address. Switching to a custom resolver — Cloudflare, Google or another public service — stops your ISP logging those lookups automatically.

It is worth being clear about the limits, though. Changing your DNS server does not mask your IP address, does not encrypt the rest of your traffic, and does not unblock geo-restricted streaming. Your queries still travel across your ISP's network equipment, so if they are not encrypted they remain vulnerable to packet sniffing.

Key features of encrypted DNS

• Query privacy: stops ISPs and attackers seeing or altering which sites you are trying to reach.
• Better security: reduces the risk of DNS spoofing and man-in-the-middle attacks.
• Targeted protection: encrypts DNS traffic and nothing else.

Encrypted DNS is the simpler, narrower option for people who want their lookups kept private without reconfiguring their whole network.

VPN versus encrypted DNS

• Scope: a VPN encrypts all traffic from your device; encrypted DNS covers only your domain lookups.
• IP address: a VPN replaces yours with the server's; encrypted DNS leaves your real IP visible.
• Geo-restrictions: a VPN can bypass them; encrypted DNS on its own cannot.
• Setup: encrypted DNS is a single setting; a VPN is an app you connect through.
• Speed: encrypted DNS adds almost no overhead; a VPN adds some, in exchange for far broader protection.

Choosing the right tool

Which one you want depends on the problem you are solving. A third-party DNS provider can improve browsing speed and make it easier to manage parental controls on a home network — but it will not deliver serious privacy or security benefits.

A VPN encrypts your connection and changes your IP address, giving you real control over your privacy. You can go online knowing nobody is able to listen in, because the connection itself is protected.

So if privacy and security are the goal, a VPN is the better choice. And since providers such as EnovaVPN bundle SmartDNS as well, you do not have to give up easy content access to get it.

Conclusion

VPNs and encrypted DNS both improve your privacy, but they are not interchangeable. A VPN is the comprehensive option; encrypted DNS is a focused tool that protects your lookups and nothing more. If all you want is an easy way to reach content by location, DNS will do the job. If you want something genuinely secure, a VPN is the stronger answer — and understanding the difference is what lets you choose deliberately rather than by accident.
