DNS Over HTTPS (DoH) vs. DNS Over QUIC (DoQ): The Battle of the Privacy Protectors

October 15, 2024, 12:01 pm, By Joyeeta Sen Rimpee

Hey there! If you’ve ever wondered how your computer magically turns "www.cute-cat-videos.com" into an actual website, you’re about to dive into the fascinating world of DNS (Domain Name System). But wait—this isn’t just any DNS story. This is about two superheroes fighting for your online privacy: DNS over HTTPS (DoH) and DNS over QUIC (DoQ). Let’s break it down in a way that won’t make your brain hurt.

What’s DNS, and Why Should You Care?

First, let’s set the stage. DNS is like the phonebook of the internet. When you type a website name into your browser, DNS translates that name into an IP address (a bunch of numbers) so your device can find the website’s server. Simple, right?

But here’s the catch: traditional DNS is like sending a postcard. Anyone who intercepts it can read it. That means your internet service provider (ISP), hackers, or even nosy governments can see what websites you’re visiting. Yikes! That’s where DoH and DoQ come in—they’re here to encrypt your DNS queries and keep your browsing habits private.

DNS Over HTTPS (DoH): The OG Privacy Protector

DoH is like the wise, older sibling who showed up first to save the day. It works by wrapping your DNS queries in an HTTPS encryption layer—the same tech that keeps your online banking secure. Here’s why DoH is cool:

• Privacy: Your DNS queries are hidden from prying eyes. Even your ISP can’t see what websites you’re visiting.

• Compatibility: Since it uses HTTPS, it works seamlessly with most existing web infrastructure.

• Widely Adopted: Big players like Mozilla Firefox and Google Chrome already support DoH.

But DoH isn’t perfect. It can sometimes be slower because it relies on HTTP/2, and it’s often criticized for centralizing DNS traffic to a few big providers (like Cloudflare or Google). Plus, it can be blocked by firewalls that don’t like encrypted traffic.

DNS Over QUIC (DoQ): The New Kid on the Block

Enter DoQ, the younger, faster, and more energetic sibling. QUIC (Quick UDP Internet Connections) is a modern protocol designed by Google to make the internet faster and more efficient. DoQ takes advantage of QUIC’s speed and reliability to encrypt DNS queries. Here’s why DoQ is turning heads:

• Speed: QUIC is built for low latency, so DoQ is faster than DoH. It’s like upgrading from a bicycle to a sports car.

• Security: Like DoH, DoQ encrypts your DNS queries, but it also reduces the risk of certain attacks because QUIC is inherently more secure.

• Decentralization: DoQ doesn’t rely on HTTP, so it’s less likely to be blocked by firewalls or controlled by a few big providers.

However, DoQ is still in its early days. It’s not as widely supported as DoH, and it requires both the client and server to support QUIC. But hey, every superhero has to start somewhere!

DoH vs. DoQ: Who Wins?

So, which one should you root for? Well, it depends on what you value most:

• Choose DoH if: You want something tried-and-true, widely supported, and easy to use right now.

• Choose DoQ if: You’re a speed demon who loves cutting-edge tech and doesn’t mind waiting for broader adoption.

In the end, both DoH and DoQ are fighting the good fight to keep your internet browsing private and secure. It’s not really a battle—it’s more like a tag team. DoH paved the way, and DoQ is building on that foundation to make things even better.

The Future of DNS Privacy

As the internet evolves, so do the tools we use to protect ourselves. DoH and DoQ are just the beginning. Who knows? Maybe someday we’ll have DNS over Quantum Entanglement (DoQE)—okay, that’s probably a stretch, but you get the idea.

The bottom line? Whether you’re team DoH or team DoQ, you’re already winning by caring about your online privacy. So go forth, browse safely, and maybe take a moment to appreciate the unsung heroes keeping your internet life secure.

And if you’re still thinking about cute cat videos, don’t worry—your DNS queries are safe with DoH and DoQ.
