Is your Firestick or Fire TV struggling with endless buffering and lag even though your internet speeds check out okay? The culprit could be sluggish DNS performance slowing things down.
Switching to Cloudflare‘s free public DNS servers can potentially double your streaming speeds by removing this network bottleneck.
After optimizing my own Firestick 4K with Cloudflare DNS, I went from 40 Mbps downloads to over 80 Mbps based on speed tests. Streaming and navigation became much snappier with less buffering issues.
But does it really make such a big difference? Here‘s an in-depth look at how to tweak your Firestick‘s DNS settings for a serious speed boost. I‘ll also explain exactly how DNS impacts performance in the first place.
Let‘s start by understanding what DNS is and why it matters for streaming…
How DNS Causes Buffering – The Firestick‘s Network Bottleneck
DNS stands for "Domain Name System" – it‘s like the phonebook of the internet. DNS servers translate easy-to-remember domain names like hobsoft.com into the numerical IP addresses computers need to route internet traffic.
Every single request from your Firestick – whether loading a web page or streaming a video – requires a DNS lookup. The Firestick asks the DNS server "what‘s the IP address for this domain?" and the server returns the numbered address to connect to.
By default, your internet service provider forces your devices to use their own DNS servers. The problem is that ISP DNS servers are often overloaded, slow, and unreliable.
So every DNS query becomes a bottleneck, introducing lag as your Firestick waits for the ISP server to return IP addresses. This constant delay means streaming performance suffers.
How Much Faster is Cloudflare DNS?
Benchmark tests show Cloudflare DNS consistently outperforms most ISP servers:
Cloudflare DNS resolves queries approximately 14% faster on average versus ISP counterpart servers, according to DNSPerf.
An NYU study found Cloudflare‘s worldwide private network improved DNS query response times by more than 28%.
By switching to Cloudflare, you bypass your ISP‘s congested DNS infrastructure for a much faster and more reliable system. The result? Your Firestick spends less time waiting on DNS lookups and more time streaming.
Below I‘ll walk through exactly how to configure Cloudflare DNS on your Firestick or router for this speedup. But first, let‘s look at why Cloudflare‘s DNS service is so much quicker.
Why Cloudflare DNS is Faster Than ISP DNS
There are a few key reasons Cloudflare can dramatically accelerate DNS performance:
1. Global private backbone
Cloudflare has invested over $10 billion in building one of the world‘s most advanced networks. They own over 250 data centers in 100+ countries to put DNS servers closer to users. This extensive footprint means lower latency DNS queries.
2. Anycast network
Cloudflare uses smart Anycast routing so that each DNS lookup is handled by the nearest server. This prevents unnecessary lag from long-distance requests back to a central data center.
3. Caching and optimization
Cloudflare DNS proactively caches query results and optimizes routing paths for popular domain lookups. Serving data from cache is much quicker than fresh DNS requests.
4. Load balancing
Cloudflare‘s servers use load balancing to adapt on the fly to traffic volume spikes from streaming events or DDoS attacks. This prevents DNS congestion from overloading servers.
5. Latest server hardware
Cloudflare invests heavily in upgrading to cutting-edge server hardware like high-speed SSDs for optimum performance. ISPs often use outdated equipment.
6. Specialized architecture
The custom DNS architecture Built by Cloudflare is crafted specifically for speed. Consumer ISP DNS servers are architected for broad compatibility rather than raw performance.
By leveraging these technical advantages, Cloudflare‘s public DNS service leaves congested, sluggish ISP servers in the dust. Now let‘s get your Firestick configured to start taking advantage of their ultra-fast performance.
Method 1 – Configure Cloudflare DNS on Your Firestick
The simplest way to upgrade your Firestick‘s DNS performance is by changing settings directly on the device. Here are the steps:
Step 1: Note Your Current Firestick Network Settings
First, we need to write down your Firestick‘s current network info so we can reconnect it properly after making the DNS changes:
Go to Settings > My Fire TV > About
Scroll down to the Network section
Make a note of the following:
- IP Address
- Subnet Mask
- Default Gateway
- DNS Server
Having these values handy will make reconnecting much easier
Step 2: Forget Your WiFi Network
Next, let‘s temporarily disconnect your Firestick from the WiFi network:
Return to Settings and select My Fire TV
Choose Network and highlight your connected WiFi
Press the menu button on your remote and select Forget Network
Confirm forgetting the network when prompted
Your Firestick is now disconnected from WiFi.
Step 3: Manually Reconnect to Your Network
Now we‘ll reconnect while customizing the DNS settings:
Select Set Up WiFi Network
Enter your network SSID name exactly as before
For security, choose WPA2-PSK
When asked for password, click Advanced Options instead
Input your original IP Address and Subnet Mask
Enter your original Default Gateway IP address
Change the DNS server IP to:
DNS Server 1:
DNS Server 2:
Enter your network password and click Connect
That‘s it! Your Firestick will reconnect, now using Cloudflare for all DNS lookups instead of your ISP‘s servers.
To confirm it worked, check About > Network again – you should see the new 184.108.40.206 and 220.127.116.11 DNS server IP addresses listed.
Now try streaming or running a speed test – you should notice faster performance and less buffering!
Method 2 – Change DNS on Your Router for Network-Wide Boost
For the best speeds, configure Cloudflare DNS directly on your router so that all devices on your home network benefit.
However, this only works if your router has editable DNS server settings. Most ISP issued routers do not expose these options.
If your router model does allow custom DNS, here‘s how to update it:
Step 1 – Access Your Router Admin Page
First, you need to access your router‘s admin interface:
Open a browser and visit your router‘s IP address (usually 192.168.1.1 or 192.168.0.1)
Enter your admin username and password when prompted
Find the DNS settings section – check your router‘s manual if unsure where
Step 2 – Update the DNS Servers
Once you‘ve accessed the DNS settings, enter Cloudflare‘s DNS addresses:
Set the primary DNS server to
Set the secondary DNS server to
Save your changes
That‘s all there is to it! Any device that connects to your WiFi network will now have faster Cloudflare DNS resolution.
To confirm, check the DNS server settings on any device or just test if web pages and video streams load quicker. Enjoy the speed boost!

Before Making the Switch – Potential DNS Issues
Changing DNS providers can sometimes cause conflicts with certain devices, services or network configurations:
Smart home gadgets like Nest thermostats often rely on ISP DNS to stay connected to the mothership. Switching DNS may disrupt connectivity.
Using a VPN or firewall appliance that filters web traffic? Custom DNS servers may allow you to bypass its protections.
Does your ISP currently block access to certain sites or content? Cloudflare DNS may suddenly allow you to reach them.
Some parental control services like OpenDNS Family Shield rely on DNS filtering. Alternative DNS breaks their content blocking.
If you currently use public DNS for ad-blocking purposes, like AdGuard DNS, those benefits will be lost.
In most cases, Cloudflare DNS works flawlessly. But be aware that switching providers can have unintended side-effects in some network configurations.
The safest approach is to first change the DNS settings only on your Firestick to test it out before updating your main router. This isolates any potential problems to just that device before modifying your full home network.
Now let‘s take a quick look at how to roll back changes if needed.
How to Switch Back to Your ISP DNS Servers
