We don’t bother to change our internet settings and generally accept whatever defaults we’re given. We believe the DNS provided by our ISP is sufficient to keep us anonymous. If nothing is out of place, pages load well, and apps can connect, there isn’t an urgent need to change DNS.
However, the more I paid attention to what DNS can actually control, the more I realized that early tweaks for speed and privacy only scratch the surface. Realizing that DNS is more than a background setting, I tried Control D, a modern, customizable DNS service. It brought clarity, and I started to understand why certain Internet pain points persist.
Most DNS services stop at resolution
Control D treats DNS as a decision layer
The main job of traditional DNS is to translate domain names into IP addresses. This way, your device always knows where to connect. However, with some services, you get extras such as blocking malicious domains and content filtering. These are useful features, but that’s also as far as most DNS services go. Beyond their core functionality, you don’t get granular control.
This is where Control D stands out. Rather than treating requests the same way, Control D decides how individual traffic is handled based on rules. So, DNS queries are not merely allowed or denied, but they are redirected through a clearly defined path determined by what the service is and what you want it to do. I can keep banking traffic local for added security, route streaming services through a specific region, and block ads entirely.
Control D supports over 850 pre-configured services, so you don’t need to manually identify which domains belong to Netflix, Disney+, or your banking app — just toggle the service and the routing applies automatically.
This approach transforms DNS from a resolver into a decision point, making it convenient to rely on a single tool to fix separate problems. Instead of layering ad blockers, device settings, and network tweaks, DNS becomes a single point where decisions — blocking, allowing, and routing — first happen.
Why DNS-level routing feels different from a VPN
Because not all traffic should be treated the same
VPNs are powerful tools, and I’ve always used one. Once connected, all traffic leaving your device appears to come from the same rerouted location. This is useful because it hides your current location, but it also creates a new problem. Local services may break, and even sensitive services like your banking app can start to trigger warnings. On top of this, search results don’t make as much sense. If Google thinks you’re in Tokyo, it will show restaurants in Tokyo.
It’s different from DNS-level routing, which only redirects specific services you choose through proxy servers rather than all traffic. This allows most of your traffic to behave normally without routing changes. Local apps remain local, and all other traffic follows the paths you’ve pre-configured.
This approach doesn’t try to replace a VPN for everything. For instance, with public Wi-Fi, I still use a free VPN that I trust. Also, whenever full encryption is required, VPNs are the right choice. However, you get precision from DNS routing without an all-or-nothing trade-off.
One DNS change can clean up your entire home network
Including devices you can’t install anything on
The problem with most privacy and filtering tools is that they’re not as effective on devices other than your laptop or phone. For instance, even though smart TVs, streaming boxes, game consoles, and smart home devices generate a lot of background traffic, they don’t support extensions and apps the same way laptops and phones do.
This is where DNS control, especially Control D, shines. As long as you configure DNS at the router level, you don’t need to set up individual configurations on different devices to follow the same baseline rules.
Consumer routers typically allow custom DNS under WAN or DHCP settings, but you can configure Control D on individual devices if your ISP-provided router locks this down.
On top of this, Control D adds profiles so that different devices on the same network can follow different sets of rules. On my kids’ devices, I implement strict rules, and on my work devices, I block social media and entertainment sites to keep them clean and predictable. It’s an implementation that’s easy to scale without increasing maintenance costs.
Seeing your DNS traffic changes how you think about privacy
Most people underestimate how noisy their devices are
If you’ve never studied DNS activity, you might underestimate how often devices reach out in the background. Apps are constantly signaling their servers, and even smart TVs may broadcast viewing habits.
From Control D’s dashboard, you get to see this traffic in real time. It shows device queries as timestamped entries. Each entry shows the device that generated it, what was requested, and the decision Control D took — block, allow, or redirect. I still find it alarming how services I barely use generate hundreds of daily requests.
Control D’s CSV export feature lets you download query logs with 24+ data columns — useful for analyzing patterns over time or for sharing evidence of suspicious device behavior with manufacturers or support teams.
However, this level of clarity helps me make smarter decisions. I can make an informed choice to block my smart TV from contacting the same analytics domain. I really don’t have to take any action, but if I do, I have enough context just by analyzing Control D’s dashboard.
Router vs. Computer DNS Settings: Here’s What Was Faster
Comparing DNS at the router versus PC level led to real improvements in my network’s speed and performance.
This is when Control D actually makes sense, and when it doesn’t
I rave about Control D a lot, but it isn’t for everyone. So, if the main goal is basic protection against malicious domains and a faster resolver, I may choose the fastest public DNS I’ve tried: NextDNS. I don’t necessarily have to upgrade to Control D.
However, if you constantly stack tools to solve related Internet problems, then you’d be far better off with Control D. It’s the right tool if you need to prioritize specific apps and want more predictable behavior across devices. It’s a tool that gives you ownership of your network behavior.
