Top Free DNS Servers in 2026: Best Public DNS for Speed, Privacy & Security
If your internet connection feels slow when opening websites, apps, or online services, changing your DNS server may be one simple setting worth trying.
In this guide, we list some of the most popular free public DNS servers you can use in 2026, including Cloudflare, Google Public DNS, Quad9, AdGuard DNS, Control D, OpenDNS, CleanBrowsing, DNS.WATCH, and other options.
What Is DNS?
DNS stands for Domain Name System. It works like a directory for the internet by translating website names into IP addresses that computers can understand.
For example, when you type a website address into your browser, your device needs to find the IP address associated with that domain. A DNS server performs this lookup so your browser can connect to the correct server.
Your internet provider normally gives you a DNS server automatically. However, you can manually change the DNS settings on your phone, computer, router, or other compatible devices.

Secondary DNS:
94.140.15.15
This makes AdGuard DNS particularly interesting for users who want an additional layer of filtering without installing a traditional browser extension.

It can be useful for people who want more control over DNS-level blocking, privacy settings, and network policies.
Why Change Your DNS Server?
Changing your DNS server does not increase the bandwidth provided by your internet plan. However, switching to another DNS resolver can change how quickly DNS lookups are completed and may provide additional security or filtering features.
Some reasons people change DNS servers include:
- Looking for faster DNS resolution
- Using a more reliable DNS resolver
- Adding security-focused DNS filtering
- Blocking advertisements or trackers
- Using family-friendly content filtering
- Getting more control over DNS requests
- Testing an alternative to the DNS supplied by an ISP
Does Changing DNS Make Internet Faster?
It can improve the time required for DNS lookups, but it does not automatically make every part of your internet connection faster.
For example, changing DNS will not increase the download speed included in your internet subscription. Your actual browsing experience can also depend on your ISP, Wi-Fi signal, server location, network congestion, and the website or service you are accessing.
Which DNS Should You Try First?
There is no universal DNS server that is guaranteed to be the fastest for every user. Different DNS providers may perform differently depending on your country, ISP, routing, and network conditions.
For a simple starting point, you can test several of the popular options in the table above. If you are mainly interested in general browsing, you might compare Cloudflare and Google Public DNS. If security is important, you can also test Quad9. For filtering, AdGuard DNS or CleanBrowsing may be worth considering.

Can I Use These DNS Servers on a Phone?
Yes. Depending on the operating system and device, DNS settings can usually be changed through network settings or through a private DNS feature.
The exact steps are different for Android, iPhone, Windows, macOS, routers, and other devices.
Can I Use These DNS Servers on a Wi-Fi Router?
Many home routers allow users to manually enter primary and secondary DNS addresses. When configured at the router level, the DNS setting can apply to multiple devices connected to the same network.
The location of the DNS setting depends on the router brand and firmware. Look for settings under sections such as Internet, WAN, Network, DHCP, or DNS.
What Is DNS Over HTTPS?
DNS Over HTTPS, commonly called DoH, is a method of sending DNS queries through HTTPS. Another technology is DNS Over TLS, or DoT.
These technologies can help protect DNS requests while they are being transported between your device and a compatible DNS resolver.
However, support and configuration vary depending on the DNS provider, operating system, browser, router, and network.
Important Things to Know Before Changing DNS
- Changing DNS does not increase your internet subscription speed.
- DNS performance can vary by location and ISP.
- Some DNS services include filtering that can block certain domains.
- Some websites or applications may behave differently when DNS filtering is enabled.
- Always keep your original DNS settings so you can restore them if necessary.
- Check the DNS provider's official documentation for the latest addresses and configuration options.
