My Roku Streaming Stick Plus (model 3830R) handles almost everything I throw at it. Then I tried pointing it to a different DNS server, and it stopped responding.
Privacy was the main reason. I didn’t love the idea of my ISP logging every app and service my TV reached out to. Ad blocking came next, since a filtering DNS service can stop a lot of tracking and ad requests before they load, and I hoped for snappier app launches too. No single moment sent me down this path; I just had some time on my hands and some general assumptions about what a DNS service could do to meet my needs.
I assumed it would take a minute. I’d done the same thing on my phone and Mac without much thought. On the Roku, I spent a good chunk of time clicking through menus looking for a field that doesn’t exist.
Can you change DNS settings on a Roku?
On a Roku, go to Settings> Network to find the basics. You can check your connection, run a speed test, and pick a Wi-Fi network. Some models let you switch to a wired connection. That’s about it.
There’s no manual IP option, no advanced menu, and no place to type in a DNS address. Roku pulls its network configuration automatically from your router through DHCP and gives you no way to override it on the device.
Believe me, I tried finding a hidden menu, and there isn’t one.
The bigger catch showed up when I started reading forums. Users have reported for years that Roku devices can send DNS requests straight to Google’s public servers (8.8.8.8 and 8.8.4.4), even when the router hands out something else. Roku hasn’t addressed this publicly, and community testing suggests the behavior varies by device, software version, and even which streaming channels are running. Either way, it explains why some people change their router settings and still see Roku traffic slip past.
How to change Roku DNS through your router
I set AdGuard DNS on my Google Nest Wifi
If the Roku won’t let you choose a DNS server, you can choose it for the whole network. Your router tells every connected device which DNS server to use when it joins. Change that setting once, and the Roku picks it up along with everything else in the house.
My network runs on Google Nest Wifi, which handles this through the Google Home app. For this test, I picked AdGuard DNS. It’s free, needs no account, and setup is as simple as typing two addresses into the app: 94.140.14.14 and 94.140.15.15. Those default servers strip out ads and trackers automatically, so I didn’t have to configure anything else to see whether the idea worked.
On Nest Wifi, the setting lives at Wi-Fi > Network settings > Advanced networking > DNS in the Google Home app. You get three choices: Automatic, your ISP’s DNS, or Custom. Custom lets you type in a primary and secondary server, with separate fields for IPv4 and IPv6.
One warning from Google’s own support page is worth repeating: if you mistype an address or pick a server that goes offline, every device on the network loses its internet connection. Double-check the numbers before you save.
How to change DNS settings on most other routers
The steps look similar no matter the brand
If you don’t use Nest Wifi, the steps on most other routers follow a similar pattern:
- Sign in to your router’s admin page or app. The address is usually printed on a sticker on the router, often something like 192.168.1.1 or 192.168.0.1.
- Look for a section labeled Internet, WAN, LAN, or DHCP. DNS settings tend to live in one of those.
- Switch DNS from automatic (your ISP’s servers) to manual.
- Enter the primary and secondary addresses from the DNS provider you picked.
- Save the changes. Some routers will restart on their own.
- Restart your Roku by going to Settings > System > Power > System restart, or just unplug it for a few seconds.
The restart matters. The Roku holds onto its old network details until it reconnects, so it won’t use the new server until it asks the router again.
Does Roku use hardcoded Google DNS?
My Streaming Stick Plus followed the router anyway
If the Roku keeps reaching Google’s servers directly, the router change alone won’t catch it. Some routers have an option to force or intercept all DNS traffic, sometimes labeled DNS redirect, DNS hijacking, or “override DNS for all clients.” Turning that on sends every DNS request on port 53 to the server you chose, no matter where a device tries to send it.
Nest Wifi doesn’t offer port 53 redirection or static routing rules inside the Google Home app. Despite that limitation, my Streaming Stick Plus honored the custom DNS immediately after a system restart. I tested this by briefly setting an unreachable IP address as the primary DNS in the Google Home app; the Roku promptly failed its network connection test instead of silently falling back to Google DNS.
Be careful with the blunt version of this, blocking 8.8.8.8 outright. Some users report their Roku acting as if it has no internet connection when Google DNS is blocked instead of redirected. Redirecting is the safer move.
What to know before changing DNS on your router
Every device in the house gets new settings
Changing DNS on the router affects every device on your network, not only the Roku. If something else in the house starts misbehaving after the switch, start with the new DNS server.
ISP-supplied routers and gateways sometimes lock the DNS setting. If yours does, you may need your own router, or you can put a mesh system in front of the gateway and set DNS there.
If you use a filtering DNS service, expect some trial and error. Roku apps lean on ad and tracking domains in odd ways, and blocking the wrong one can break a channel. Most services let you allowlist a domain in a few clicks.
I’ve been running this setup for three weeks, and the Roku home screen looked different immediately. The ad banner next to the main menu grid failed to load, leaving a clean, static placeholder. Ad-supported platforms like Pluto TV and The Roku Channel still streamed smoothly. None of the primary subscription apps broke, and buffering times stayed the same.
AdGuard DNS vs. NextDNS for a home network
Why I’ll probably switch for the logs alone
AdGuard got the job done, but it works like a black box. The free public servers don’t show me what they block, so I have no record of what my Roku actually tried to reach.
The impressive NextDNS fills most of that gap. A free account gets you a dashboard that logs queries across the network, and you choose which blocklists to run. Nest Wifi can’t send the account identifier NextDNS normally relies on, so you’d use its Linked IP option instead, which ties your home connection to your account. The catch is that every device then shows up as one household. The logs won’t label anything as coming from Roku, though Roku’s own domains are easy enough to spot in the list. If your ISP ever changes your IP address, you relink it.
The free plan caps out at 300,000 queries per month before filtering shuts off, and a modern home with smart TVs and connected gadgets can burn through that allowance within a week or two. The paid plan costs $1.99 a month (or $19.90 annually). For my setup, that small fee is worth it for the logs alone. I want to know how chatty the Roku really is when I’m not watching anything, and AdGuard’s free servers can’t tell me.
Is router-level DNS worth it for Roku?
Roku should offer a native DNS menu. Until it does, handing the job to your router takes less than 10 minutes and cuts out a lot of tracking you never asked for. I would set it up again without hesitation. If a cleaner home screen sounds good to you, router-level DNS is one of the easiest weekend upgrades you can make to your streaming setup.
