When configuring an Internet connection manually, two DNS addresses appear repeatedly:

• 8.8.8.8 – Google Public DNS
• 1.1.1.1 – Cloudflare Public DNS

Both are free public recursive DNS services and can replace the DNS servers automatically assigned by your Internet Service Provider (ISP). Google describes Google Public DNS as a free global DNS resolution service, while Cloudflare operates 1.1.1.1 as its public recursive resolver.

Both services are fast, globally distributed, support modern DNS security technologies, and are suitable for many home and business Internet connections.

However, they are not identical.

This guide explains the differences between Google DNS 8.8.8.8 and Cloudflare DNS 1.1.1.1, including speed, privacy, security, encryption, reliability, filtering, configuration and troubleshooting.

What Is DNS?

DNS stands for Domain Name System.

Computers communicate using IP addresses, but people normally access websites using names.

For example:

www.example.com

Your computer needs to determine the IP address associated with that hostname before establishing a connection.

A simplified process is:

User enters website name → DNS query → DNS resolver → IP address returned → browser connects to server

DNS therefore functions somewhat like the Internet's directory service.

Without working DNS, you may still have an Internet connection but websites may fail to open by name.

For example, a network might successfully ping:

8.8.8.8

while:

www.google.com

fails to resolve.

That frequently indicates a DNS-related problem.

What Is Google Public DNS – 8.8.8.8?

Google Public DNS is Google's globally available recursive DNS resolution service.

Its most commonly used IPv4 addresses are:

Primary DNS
8.8.8.8

Secondary DNS
8.8.4.4

Google states that its Public DNS service supports traditional DNS over UDP/TCP as well as encrypted DNS over TLS (DoT) and DNS over HTTPS (DoH).

Google Public DNS has been available since 2009 and is one of the world's best-known public DNS services.

What Is Cloudflare DNS – 1.1.1.1?

Cloudflare's public recursive DNS service uses:

Primary DNS
1.1.1.1

Secondary DNS
1.0.0.1

Cloudflare positions the resolver around performance and privacy and operates it across its globally distributed network. Cloudflare also supports encrypted DNS technologies including DoH and DoT.

8.8.8.8 vs 1.1.1.1 – Quick Comparison

Feature	Google Public DNS	Cloudflare DNS
Provider	Google	Cloudflare
Primary IPv4	8.8.8.8	1.1.1.1
Secondary IPv4	8.8.4.4	1.0.0.1
Free	Yes	Yes
Public recursive DNS	Yes	Yes
DNSSEC validation	Yes	Yes
DNS over HTTPS	Yes	Yes
DNS over TLS	Yes	Yes
Global infrastructure	Yes	Yes
Anycast routing	Yes	Yes
Standard malware filtering	No	No
Separate filtering service	Not the purpose of standard Google DNS	Yes – 1.1.1.1 for Families
Privacy emphasis	Strong	Particularly privacy-focused
Suitable for home use	Yes	Yes
Suitable for troubleshooting	Excellent	Excellent

Neither resolver can universally be declared the fastest because DNS performance depends heavily on your ISP, routing, geographic location and the resolver node your connection reaches.

DNS Server Addresses

Google Public DNS IPv4

Primary:

8.8.8.8

Secondary:

8.8.4.4

Google officially recommends these addresses when configuring clients for Google Public DNS.

Cloudflare DNS IPv4

Primary:

1.1.1.1

Secondary:

1.0.0.1

Cloudflare officially provides these two addresses for redundancy.

IPv6 DNS Addresses

Both providers support IPv6.

Google Public DNS IPv6

2001:4860:4860::8888

2001:4860:4860::8844

Cloudflare DNS IPv6

2606:4700:4700::1111

2606:4700:4700::1001

Cloudflare documents these IPv6 resolver addresses alongside its IPv4 addresses.

Which DNS Is Faster?

This is one of the most common questions:

Is 1.1.1.1 faster than 8.8.8.8?

There is no universal answer.

DNS speed depends on factors such as:

• Your physical location
• ISP routing
• ISP peering arrangements
• Resolver node location
• Network congestion
• DNS cache status
• IPv4 versus IPv6 routing
• Wi-Fi or LAN latency
• Router performance
• VPN configuration
• Corporate firewall configuration

Cloudflare may be faster on one Internet connection while Google may be faster on another.

Therefore, DNS should be benchmarked from the actual Internet connection where it will be used.

Does Faster DNS Increase Internet Speed?

Not exactly.

Changing DNS from your ISP's resolver to 1.1.1.1 or 8.8.8.8 will normally not increase your broadband bandwidth.

For example, changing DNS will not convert:

100 Mbps Internet

into:

200 Mbps Internet.

DNS primarily affects the name-resolution stage.

A faster resolver may make the initial connection to websites feel quicker, particularly when applications perform many uncached DNS lookups.

Once a large file download has started, DNS normally has little or no effect on the actual transfer speed.

DNS Latency Example

Suppose one resolver takes:

15 ms

to answer a query.

Another takes:

60 ms.

The first resolver can potentially start the connection process around 45 milliseconds sooner for that lookup.

A modern webpage may contact many different domains for:

• Images
• JavaScript
• Fonts
• APIs
• Advertising
• Analytics
• CDN resources
• Authentication services

Efficient DNS resolution can therefore contribute to a more responsive browsing experience, although browser and operating-system DNS caches reduce repeated lookups.

Privacy: 8.8.8.8 vs 1.1.1.1

Privacy is an important consideration because your DNS resolver processes requests for the domain names your devices attempt to access.

Google Public DNS Privacy

Google states that client IP addresses are temporarily logged and erased within approximately one or two days. Information such as ISP and city/metro-level location can be retained longer for service performance and security purposes.

Google also states that stored Public DNS information is not associated with Google accounts and that DNS log data is not combined with personal information supplied for other Google services in the manner described in its FAQ.

Cloudflare 1.1.1.1 Privacy

Cloudflare explicitly positions 1.1.1.1 as privacy-focused.

According to Cloudflare's current Public DNS privacy documentation, it does not sell or share Public Resolver users' personal data with third parties for advertising. Cloudflare states that source IP addresses are generally not stored in non-volatile storage, with a limited exception for randomly sampled network packets used for network troubleshooting and DoS mitigation. Truncated IP information in Public Resolver logs is deleted within 25 hours.

Privacy Advantage

For users whose primary consideration is minimizing DNS-related data retention, Cloudflare 1.1.1.1 is often the more privacy-oriented choice based on the providers' published policies.

That does not mean Google Public DNS is insecure. It means their documented data-handling approaches differ.

DNS Encryption

Traditional DNS commonly uses:

UDP port 53

or:

TCP port 53.

Traditional DNS queries are normally unencrypted.

Both Google and Cloudflare support modern encrypted DNS technologies.

DNS over HTTPS – DoH

DNS over HTTPS sends DNS requests through HTTPS.

Cloudflare documents DoH as using HTTPS, normally over:

TCP/443

This helps protect DNS traffic against observation and modification while it travels between the client and resolver.

Google Public DNS also supports DoH.

Modern browsers including Chrome, Edge and Firefox can support secure DNS configurations.

DNS over TLS – DoT

DNS over TLS encrypts DNS queries using TLS.

DoT commonly uses:

TCP/853

Cloudflare documents support for DoT on port 853.

Google Public DNS also supports DNS over TLS.

Important: Changing DNS Does Not Automatically Encrypt DNS

This is frequently misunderstood.

Simply entering:

1.1.1.1

or:

8.8.8.8

in the traditional IPv4 DNS configuration does not necessarily mean DNS traffic is encrypted.

If the operating system or application sends normal DNS over port 53, queries remain traditional DNS.

To obtain encrypted DNS, the client must actually use:

• DNS over HTTPS
• DNS over TLS
• or another supported encrypted DNS mechanism.

DNSSEC Support

DNSSEC stands for:

Domain Name System Security Extensions

DNSSEC uses cryptographic signatures to help DNS resolvers verify that signed DNS data is authentic and has not been modified.

Cloudflare states that 1.1.1.1 performs DNSSEC validation.

Google Public DNS also supports DNSSEC validation.

DNSSEC does not encrypt DNS queries.

This distinction is important:

DNSSEC = validates DNS data

DoH/DoT = encrypts DNS communication between client and resolver

They solve different security problems.

Does 1.1.1.1 Block Malware?

Standard:

1.1.1.1

does not perform content filtering.

Cloudflare specifically states that its standard public resolver is designed for normal DNS resolution rather than content blocking.

However, Cloudflare provides additional DNS addresses for filtering.

Cloudflare Malware Blocking DNS

Primary:

1.1.1.2

Secondary:

1.0.0.2

These are designed to block domains associated with malware and phishing.

Cloudflare Malware + Adult Content Filtering

Primary:

1.1.1.3

Secondary:

1.0.0.3

These add adult-content filtering in addition to malware/phishing protection.

This can be useful for:

• Families
• Children's computers
• Home networks
• Basic security filtering
• Guest Wi-Fi

However, DNS filtering should not replace antivirus, endpoint security, firewall protection or web security controls.

Is Google 8.8.8.8 a Malware-Blocking DNS?

Standard Google Public DNS is primarily a recursive DNS resolution service rather than a configurable content-filtering service.

Do not assume that using:

8.8.8.8

means malicious websites will automatically be blocked.

Google describes Public DNS around speed, security and correct DNS resolution rather than as a parental-control or general content-filtering DNS service.

Reliability

Both Google and Cloudflare operate extremely large global networks.

Both use Anycast networking.

With Anycast, the same DNS IP address can be advertised from many locations around the world. Network routing directs the user toward an appropriate available location.

Google confirms that requests to addresses such as 8.8.8.8 and 8.8.4.4 are routed using Anycast.

Cloudflare similarly operates 1.1.1.1 through its globally distributed infrastructure.

This architecture provides:

• Low latency
• Geographic distribution
• Fault tolerance
• Large-scale capacity
• Better resilience

Can I Use 8.8.8.8 and 1.1.1.1 Together?

Technically, you can configure:

Preferred DNS:

1.1.1.1

Alternate DNS:

8.8.8.8

or reverse them.

However, there is an important consideration.

Operating systems do not always treat the secondary resolver as a simple, predictable "backup only" server. Resolver behavior can vary.

For consistent privacy policies, filtering behavior and troubleshooting, it is often cleaner to use both addresses from the same provider.

For example:

Google

8.8.8.8

8.8.4.4

Cloudflare

1.1.1.1

1.0.0.1

For critical networks, redundancy strategy should be tested rather than assuming that two different public DNS providers automatically create perfect failover.

Google itself notes that its free Public DNS service has no SLA and recommends alternative resolution arrangements for critical services.

Which DNS Is Better for Gaming?

DNS is sometimes promoted as a method of reducing gaming ping.

This claim needs qualification.

Changing DNS may improve:

• Game-server hostname lookup
• Login-server lookup
• Matchmaking-service lookup
• Launcher connectivity
• Initial service discovery

But once the gaming connection has been established, DNS usually does not control the network route between your PC and the game server.

Therefore, changing from:

8.8.8.8

to:

1.1.1.1

will not automatically reduce a 100 ms in-game ping to 20 ms.

Actual game latency is influenced more by:

• ISP routing
• Game-server location
• Wi-Fi quality
• Network congestion
• Packet loss
• VPN use
• ISP peering
• Broadband technology

Choose whichever resolver provides stable and fast DNS responses on your connection.

Which DNS Is Better for Streaming?

Both can work well for services such as video streaming.

DNS can sometimes influence CDN selection because large content providers use sophisticated traffic-routing systems.

Therefore, one resolver might occasionally lead to a different CDN endpoint than another.

If streaming performance changes after switching DNS, test both providers rather than assuming one is universally superior.

Which DNS Is Better for Business Networks?

The answer depends on the network.

Public DNS is useful for:

• Small offices
• Guest networks
• Troubleshooting
• Internet-only workstations
• Basic router configurations

However, organizations using:

• Active Directory
• Internal DNS zones
• Domain controllers
• Internal applications
• Split DNS
• VPN DNS
• Private hostnames

must be careful.

Important Warning for Windows Active Directory

Do not normally configure Active Directory domain-member PCs directly with:

8.8.8.8

or:

1.1.1.1

as their primary DNS resolver.

Active Directory relies heavily on DNS records to locate:

• Domain controllers
• Kerberos services
• LDAP
• Global Catalog servers
• Domain services

Domain members should normally use the organization's internal Active Directory DNS servers.

Those DNS servers can then use public DNS through appropriate forwarding or recursive configuration.

Incorrect public DNS configuration on domain PCs can cause:

• Domain login problems
• Group Policy failures
• Domain controller discovery failures
• Authentication problems
• Shared resource failures
• DNS lookup problems

How to Configure 1.1.1.1 or 8.8.8.8 in Windows 11

Open:

Settings → Network & Internet

Select:

Wi-Fi

or:

Ethernet

Open your active connection.

Find:

DNS server assignment

Click:

Edit

Choose:

Manual

Enable:

IPv4

For Cloudflare enter:

Preferred DNS:

1.1.1.1

Alternate DNS:

1.0.0.1

For Google enter:

Preferred DNS:

8.8.8.8

Alternate DNS:

8.8.4.4

Save the configuration.

Configure DNS Through Windows Network Connections

Press:

Windows + R

Type:

Press Enter.

Right-click the active network adapter.

Select:

Properties

Select:

Internet Protocol Version 4 (TCP/IPv4)

Click:

Properties

Select:

Use the following DNS server addresses

Enter your preferred DNS configuration.

Flush DNS Cache After Changing DNS

Open Command Prompt as Administrator.

Run:

ipconfig /flushdns

You should receive a message similar to:

Successfully flushed the DNS Resolver Cache.

This removes cached DNS entries from the Windows DNS client cache.

Check Your Current DNS Servers

Open Command Prompt and run:

ipconfig /all

Locate your active network adapter.

Look for:

DNS Servers

You may see:

1.1.1.1
1.0.0.1

or:

8.8.8.8
8.8.4.4

Test Google DNS Using NSLOOKUP

Run:

nslookup google.com 8.8.8.8

This explicitly asks Google Public DNS to resolve google.com.

Test Cloudflare DNS Using NSLOOKUP

Run:

nslookup google.com 1.1.1.1

Compare the responses.

You can repeat tests with different domains.

Test DNS Using PowerShell

Windows PowerShell provides:

Resolve-DnsName google.com -Server 8.8.8.8

and:

Resolve-DnsName google.com -Server 1.1.1.1

This is particularly useful for administrators troubleshooting DNS resolution.

Basic Reachability Test

You can also test whether the resolver IP is reachable:

ping 8.8.8.8

and:

ping 1.1.1.1

However, ping and DNS are different protocols.

A successful ping does not prove that DNS queries are working, and a failed ping does not always prove that the DNS service is unavailable, because ICMP may be filtered.

Use actual DNS queries with nslookup or Resolve-DnsName for DNS testing.

Troubleshooting: Internet Works by IP but Not by Website Name

Suppose:

ping 8.8.8.8

works.

But:

ping google.com

returns a name-resolution error.

This strongly suggests checking DNS.

Try:

nslookup google.com

Then explicitly test:

nslookup google.com 8.8.8.8

and:

nslookup google.com 1.1.1.1

If the public resolver works but your default resolver fails, investigate:

• Router DNS
• ISP DNS
• DHCP settings
• VPN software
• Firewall rules
• Endpoint security
• DNS proxy software
• Windows DNS Client
• Network adapter configuration

DNS_PROBE_FINISHED_NXDOMAIN

Chrome may display:

DNS_PROBE_FINISHED_NXDOMAIN

This generally means DNS resolution indicates that the requested domain does not exist, although configuration or caching problems can sometimes contribute.

Possible troubleshooting steps include:

ipconfig /flushdns

Restarting the router.

Restarting the network adapter.

Checking the domain spelling.

Testing another resolver.

For example:

nslookup example.com 1.1.1.1

and:

nslookup example.com 8.8.8.8

If both public resolvers return NXDOMAIN, the issue may be with the domain's DNS configuration rather than your local resolver.

Should You Change DNS on the PC or Router?

You have two common options.

Configure DNS on Individual Devices

Useful when:

• Testing DNS
• Troubleshooting one computer
• Different devices require different DNS
• You do not control the router

Configure DNS on the Router

Useful when you want many DHCP clients to receive the same DNS configuration.

For example:

Router DNS:

1.1.1.1

1.0.0.1

Then computers, phones, TVs and other devices may receive those DNS addresses automatically through DHCP.

However, some routers act as DNS proxies, so clients may show the router's IP address as their DNS server even though the router forwards queries upstream.

Can DNS Fix "Some Websites Open but Others Don't"?

Sometimes.

If only certain websites fail, DNS should be one of the troubleshooting areas.

Try:

nslookup problemwebsite.com 8.8.8.8

Then:

nslookup problemwebsite.com 1.1.1.1

If one resolver returns valid records while another consistently fails, DNS may be involved.

But selective website failures can also be caused by:

• IPv6 problems
• MTU issues
• Firewall filtering
• VPN configuration
• Proxy settings
• CDN routing
• Browser extensions
• TLS/certificate errors
• ISP routing
• Antivirus web protection

Do not assume every website-opening problem is DNS-related.

1.1.1.1 for Families

One useful Cloudflare feature is its separate family-filtering resolver.

Malware Blocking

1.1.1.2

1.0.0.2

Malware + Adult Content Blocking

1.1.1.3

1.0.0.3

Cloudflare states that when a queried domain is classified as malicious under its Families service, the filtering resolver can return 0.0.0.0 instead of the real destination.

This provides a simple DNS-level layer of protection.

Does Public DNS Replace Antivirus?

No.

DNS filtering and antivirus solve different problems.

DNS security may prevent access to certain known malicious domains.

Antivirus/endpoint protection may detect:

• Malicious executables
• Trojans
• Ransomware
• Scripts
• Exploits
• Suspicious processes
• Infected documents
• Behavioral threats

A secure environment should use multiple protection layers.

Does DNS Hide Browsing from Your ISP?

Traditional DNS does not.

If you use ordinary DNS over port 53, DNS requests can normally be observed by network intermediaries.

Using DoH or DoT encrypts DNS communication between your device and the DNS resolver. Cloudflare explains that encrypted DNS protects queries from being read or modified while traveling between the client and resolver.

However, encrypted DNS does not make you anonymous on the Internet.

Your ISP may still observe connection metadata and destination IP addresses, and websites can still identify visitors through many other mechanisms.

DNS encryption is not the same thing as a VPN.

Cloudflare WARP vs 1.1.1.1 DNS

These should not be confused.

Using:

1.1.1.1

as your DNS resolver changes DNS resolution.

Cloudflare's WARP client can protect a broader portion of device traffic.

Cloudflare explicitly distinguishes WARP from the basic DNS resolver, noting that WARP encrypts traffic beyond DNS.

Advantages of Google Public DNS

Google Public DNS offers:

• Large global infrastructure
• Long operating history
• High reliability
• Anycast routing
• DNSSEC validation
• IPv4 and IPv6
• DNS over HTTPS
• DNS over TLS
• Easy configuration
• Excellent troubleshooting utility
• No DNS redirection according to Google's service description

It is an excellent general-purpose public resolver.

Advantages of Cloudflare 1.1.1.1

Cloudflare offers:

• Strong privacy-focused policies
• Large global infrastructure
• Fast DNS resolution
• Anycast routing
• DNSSEC validation
• IPv4 and IPv6
• DNS over HTTPS
• DNS over TLS
• Separate malware-filtering DNS
• Separate family-filtering DNS
• Easy setup

Cloudflare also supports privacy technologies such as Oblivious DNS over HTTPS in relevant configurations.

Disadvantages of Public DNS

Using any third-party public resolver has considerations.

Your DNS queries are being sent to the selected resolver provider instead of your ISP's resolver.

Possible issues include:

• Provider dependency
• Routing differences
• CDN geolocation differences
• Corporate DNS incompatibility
• Local hostname resolution failures
• DNS filtering policy differences
• VPN DNS conflicts
• ISP interception in some networks

Public DNS should therefore be tested before large-scale business deployment.

Google DNS vs Cloudflare DNS – Which Should You Choose?

A practical recommendation is:

Choose Cloudflare 1.1.1.1 if:

• Privacy is a major priority
• It benchmarks faster on your connection
• You want Cloudflare's filtering variants
• You want a simple privacy-focused public resolver

Choose Google 8.8.8.8 if:

• It performs better on your ISP
• You prefer Google's established DNS infrastructure
• You need a widely recognized resolver for testing
• You want a reliable general-purpose public resolver

For troubleshooting:

Test both.

nslookup example.com 8.8.8.8

nslookup example.com 1.1.1.1

This is more useful than assuming one provider is always better.

Recommended Configurations

Final Comparison

Both Google Public DNS 8.8.8.8 and Cloudflare DNS 1.1.1.1 are excellent public recursive DNS services.

Cloudflare has a particularly strong privacy-focused design and provides convenient filtering variants, while Google Public DNS has a long track record and extensive global infrastructure.

For many home users, either is a substantial alternative to an unreliable ISP DNS resolver.

The most important point is that there is no universal fastest DNS server.

The best DNS server is the one that provides the best combination of:

low latency + reliability + privacy + security + compatibility

for your particular network.

For technically managed environments, test both providers from the actual ISP connection before deciding.
