Slow websites, delayed page loading, and connection errors can make a good internet connection feel frustrating. Sometimes, the problem is your DNS configuration rather than your Wi-Fi signal or broadband speed.
The best DNS settings in 2026 may help websites begin loading more quickly if your current DNS resolver is slow or unreliable. Google Public DNS and Cloudflare DNS are two popular free alternatives worth testing.
However, changing DNS does not automatically increase download speeds, eliminate video buffering, or fix a weak Wi-Fi signal. The improvement depends on your existing resolver, network conditions, and the cause of the problem.
Quick answer: Google Public DNS (8.8.8.8, 8.8.4.4) and Cloudflare DNS (1.1.1.1, 1.0.0.1) are both reasonable choices for everyday browsing. Neither is always faster. Test one at a time on your connection and keep the resolver that works most reliably.
In this guide, you’ll learn which DNS addresses to use, how to change them on Windows 11, Android, and compatible routers, and how to test whether a different resolver actually makes a difference.
What Is DNS, and How Does It Affect Internet Speed?
The Domain Name System (DNS) translates website names, such as example.com, into IP addresses that devices use to locate online services.
Think of DNS as an internet directory. When you visit a website, your device may need to resolve its domain name before connecting to the appropriate server.
If this lookup takes longer than expected, the beginning of the connection can be delayed. A responsive DNS resolver may reduce that delay, especially when your device needs to look up a domain that isn’t already cached.
DNS is only one part of loading a website, though. Your browser must still connect to the server, download resources, and display the page.
| Internet problem | Can changing DNS help? |
|---|---|
| Delayed DNS lookups | Possibly |
| Certain domains fail to resolve | Possibly |
| Consistently slow downloads | Usually not |
| Weak Wi-Fi signal | No |
| Video buffering caused by congestion | Usually not |
| Internet provider outage | No |
| Slow or unavailable website server | Usually not |
The important distinction: DNS can affect how quickly a connection to a website gets started, but it is not a general-purpose internet speed booster.
Best DNS Settings in 2026: Google vs Cloudflare
Google Public DNS and Cloudflare DNS are established public resolver services. Either is a reasonable starting point when testing an alternative to your internet service provider’s DNS.
1. Google Public DNS
Google Public DNS provides domain-name resolution for general internet use.
IPv4 addresses:
- Preferred DNS:
8.8.8.8 - Alternate DNS:
8.8.4.4
IPv6 addresses:
- Preferred DNS:
2001:4860:4860::8888 - Alternate DNS:
2001:4860:4860::8844
Google DNS is worth testing if you want a widely available public resolver for everyday browsing. However, its popularity does not mean it will always be the fastest option on your connection.
See Google’s official Public DNS configuration guide for setup instructions.
2. Cloudflare DNS
Cloudflare operates a public DNS resolver with standard addresses for general-purpose domain resolution.
IPv4 addresses:
- Preferred DNS:
1.1.1.1 - Alternate DNS:
1.0.0.1
IPv6 addresses:
- Preferred DNS:
2606:4700:4700::1111 - Alternate DNS:
2606:4700:4700::1001
Cloudflare is another practical option to test against your existing resolver. It also offers optional DNS filtering through Cloudflare Families.
The standard 1.1.1.1 resolver does not automatically block every malicious website, advertisement, or tracker.
Read the official Cloudflare 1.1.1.1 setup guide for more information.
Google DNS vs Cloudflare DNS: Which Is Better?
| Feature | Google Public DNS | Cloudflare standard DNS |
|---|---|---|
| Primary IPv4 | 8.8.8.8 |
1.1.1.1 |
| Secondary IPv4 | 8.8.4.4 |
1.0.0.1 |
| Everyday browsing | Suitable | Suitable |
| Encrypted DNS | Supported in compatible configurations | Supported in compatible configurations |
| Optional family filtering | Not provided by the standard resolver alone | Available through Cloudflare Families |
| Guaranteed to be fastest everywhere | No | No |
My recommendation: Try Cloudflare first if you want a simple starting point, then compare it with Google Public DNS and your original provider. Keep the option that performs reliably on your connection.
This is a testing recommendation, not a claim that Cloudflare is universally faster. Your location, internet provider, routing, and DNS caching can affect the results.
Also, don’t assume that preferred and alternate DNS fields always operate as a strict primary-and-backup pair. Devices and operating systems can select and use configured resolvers differently.
How to Change DNS Settings on Windows 11
Windows 11 allows you to configure DNS for an individual network connection. Before changing anything, record your existing configuration so you can restore it if necessary.
Step 1: Open the Router Administration Page
Connect to your home network and open a browser. Enter your router’s administration address, which is often printed on the device or documented in its manual.
Sign in using your router’s administrator credentials.
Step 2: Find the DNS Settings
Look for a section named Internet, WAN, Network, or DHCP. The DNS settings may appear in different locations depending on the manufacturer.
If your router allows manual DNS configuration, enter the addresses for Google Public DNS or Cloudflare DNS. Save the changes when finished.
Step 3: Reconnect Your Devices
Reconnect your devices or renew their network connections so they can obtain updated settings where necessary.
Finally, test websites on more than one device. If the new configuration causes problems, restore the previous settings.
Some routers, VPN configurations, and internet providers manage DNS differently. Therefore, changing DNS on the router may not override every device’s DNS configuration.

How to Change DNS Settings on Android
Step 1: Open Private DNS
Open Settings and search for Private DNS. On many devices, you can find it under Network & internet or Connections.
Select the option to specify a Private DNS provider hostname.
Step 2: Enter the Provider Hostname
For Cloudflare, enter:
one.one.one.one
For Google Public DNS, enter:
dns.google
These hostnames are used for DNS-over-TLS connections. They are not the same as the IPv4 addresses used in the Windows instructions above.
Step 3: Save and Check Your Browsing
Save the hostname and reconnect if necessary. Then, open several websites to confirm that your connection works.
On compatible Android versions, Private DNS can apply across different networks. However, a VPN or another application may use its own DNS configuration, so your device’s Private DNS setting may not control every lookup.
If your phone cannot resolve websites after the change, return to the Private DNS setting and select Automatic. You can then investigate the connection before trying another provider.
How to Change DNS on Your Router
Changing DNS on your router may allow multiple devices to use the new configuration. The result depends on your router, internet provider, and how DNS settings are distributed across your network.
- Connect to your home network.
- Open your router’s administration page using the manufacturer’s instructions.
- Sign in with your administrator credentials.
- Find the Internet, WAN, or DNS section.
- Record the existing DNS addresses.
- Enter your chosen DNS addresses if manual configuration is supported.
- Save the changes and reconnect devices if necessary.
For Cloudflare, use 1.1.1.1 and 1.0.0.1. For Google, use 8.8.8.8 and 8.8.4.4.
Some internet providers restrict DNS changes on supplied equipment. If you cannot find the relevant setting, check the router documentation or configure DNS on an individual device instead.
See Cloudflare’s router setup instructions for additional guidance.
Important: Don’t change unrelated WAN, IP address, or gateway settings. If your connection stops working, restore the original configuration before trying another approach.
How to Test Whether Your New DNS Is Faster
Changing DNS settings does not guarantee faster browsing. Compare DNS response times under similar conditions rather than relying on one website visit or a single broadband speed test.
Step 1: Record Your Starting Point
Before changing your DNS settings, note your current configuration and test your usual connection.
Open several websites and observe whether pages take time to begin loading or display DNS-related errors. Keep your device, internet connection, and general testing conditions as consistent as possible.
Step 2: Test Cloudflare DNS
On Windows, open Command Prompt and run:
nslookup example.com 1.1.1.1
This asks Cloudflare’s resolver to look up example.com. Check whether the command returns a valid answer or reports a resolution problem.
Step 3: Test Google Public DNS
Next, run:
nslookup example.com 8.8.8.8
Compare the result with the Cloudflare test. If your command output includes a response-time figure, record it, but remember that a single lookup is not a reliable benchmark by itself.
Step 4: Repeat the Tests
Repeat each test several times. For a fairer comparison, test more than one domain and avoid drawing conclusions from a single result.
DNS caching, the network route to the resolver, and temporary congestion can affect the results. Additionally, your operating system or application may reuse cached answers, which can make repeated lookups appear faster.
For that reason, treat these commands as a basic resolution check rather than a complete measure of real-world browsing performance.
Step 5: Compare Your Results
Use a simple table to record your own observations. Fill in the response times only when you have actually measured them.
| Test | Cloudflare DNS | Google Public DNS |
|---|---|---|
| DNS resolution successful? | Record result | Record result |
| Response time, if reported | Record measurement | Record measurement |
| Websites load reliably? | Record observation | Record observation |
| Overall experience | Record observation | Record observation |
Ultimately, keep the resolver that gives you reliable results and a better experience on your connection. If the results are similar, there may be little practical reason to change your current settings.
Should You Flush Your DNS Cache?
Windows maintains a local DNS cache to reduce repeated lookups. Clearing it can help troubleshoot stale entries or unexpected domain-resolution problems, but it is not mandatory after every DNS change.
To clear the Windows DNS cache:
- Open Command Prompt.
- Enter the command below.
- Press Enter.
ipconfig /flushdns
Windows should report that the DNS resolver cache was successfully flushed.
This clears entries from the local Windows DNS resolver cache. It does not clear every cache maintained by your browser, router, or remote DNS provider, and it does not guarantee faster browsing.
DNS Privacy, Security, and Family Filtering
DNS selection affects more than performance. It can also influence how DNS queries are transported and whether certain domains are filtered.
What encrypted DNS does
DNS-over-HTTPS (DoH) and DNS-over-TLS (DoT) encrypt DNS queries between a compatible client and resolver. This helps prevent other parties on the network from easily reading or modifying those requests in transit.
Encryption does not make all your internet activity anonymous. Websites, applications, and other network services may still collect information about your activity. Review a provider’s published privacy documentation before choosing a service.
What DNS filtering does
Cloudflare offers optional family-filtering resolvers.
Malware blocking:
1.1.1.21.0.0.2
Malware and adult-content blocking:
1.1.1.31.0.0.3
These services are designed to block DNS queries for domains classified in the relevant categories. They are not a complete parental-control or cybersecurity solution. Some threats may not be blocked, and classification errors can occur.
For supported addresses and filtering details, consult Cloudflare’s official DNS documentation.
DNS Privacy and Security: What You Should Know
Your DNS provider can receive information about the domain names your device looks up. Consequently, privacy practices and the way DNS requests are transmitted are important considerations when choosing a resolver.
Google Public DNS and Cloudflare DNS support encrypted DNS options on compatible clients. DNS-over-HTTPS (DoH) and DNS-over-TLS (DoT) can help protect DNS requests from being read or modified while travelling between your device and the resolver.
However, encrypted DNS does not make all browsing activity anonymous. Websites, applications, your internet provider, and other services may still collect information through other means.
It is also important to distinguish ordinary DNS resolution from domain filtering. Standard Cloudflare DNS at 1.1.1.1 does not automatically block every advertisement, tracker, or malicious website.
Cloudflare offers alternative resolver addresses for specific filtering needs:
- Malware blocking:
1.1.1.2and1.0.0.2 - Malware and adult-content blocking:
1.1.1.3and1.0.0.3
These options provide domain-level filtering, not complete protection against every online threat. If you use a filtered resolver, test it with the services and websites you need.

Frequently Asked Questions
Which DNS is fastest in 2026?
There is no universally fastest DNS provider. Cloudflare DNS and Google Public DNS are both worth testing, but performance depends on your location, ISP, routing, and network conditions.
Should I use Google DNS or Cloudflare DNS?
Start with either provider and test your usual websites. If one offers more consistent DNS resolution on your connection, keep it. Otherwise, you may not notice a meaningful difference.
Will changing DNS increase my internet speed?
Changing DNS may reduce delays associated with domain lookups. However, it will not increase your internet plan’s bandwidth or automatically fix buffering, weak Wi-Fi, or network congestion.
Is Cloudflare DNS safer than Google DNS?
Both provide public DNS services and support encrypted DNS options on compatible clients. Your overall security also depends on software updates, browser protection, safe browsing habits, and the security of your device.
Can I change DNS on my phone and router?
Yes, if your device or router supports manual DNS configuration. Android Private DNS commonly uses a provider hostname, while routers may allow you to enter DNS server addresses directly.
Why does my internet stop working after changing DNS?
The address may have been entered incorrectly, the resolver may be unreachable from your network, or another setting may be interfering. Restore your previous DNS configuration first, confirm that browsing works, and then troubleshoot the cause.
Does changing DNS block advertisements?
Not necessarily. Standard Google Public DNS and Cloudflare DNS are not designed to block every advertisement. Some DNS providers offer filtering options, but domain-level filtering is not the same as a full ad blocker.
Final Verdict: Which DNS Settings Should You Use?
For most everyday users, Google Public DNS and Cloudflare DNS are sensible options to test in 2026. Both provide straightforward configuration, and neither is guaranteed to outperform the other on every connection.
If you want to choose based on performance, test each provider under similar conditions and record the results. If privacy is a priority, check whether encrypted DNS is enabled and understand the provider’s privacy practices.
Most importantly, remember that DNS is only one part of your internet connection. If your connection remains slow after changing resolvers, investigate Wi-Fi signal strength, router performance, your ISP, and the website or application itself.
The best DNS settings are the ones that work reliably for your device and network—not simply the ones with the most popular IP addresses.
