Every time you type a website address, your internet provider sees it. They log it. They can sell that data. And they’re slowing you down while doing it.
Switching to a better DNS server takes 60 seconds and immediately speeds up your browsing while hiding your activity from your ISP. Here are the fastest, most private DNS servers you should use in 2026.
What is DNS and why does it matter?
DNS (Domain Name System) is like the internet’s phone book. When you type “google.com,” DNS translates that into an IP address like 172.217.164.142 so your browser knows where to connect.
Your ISP provides DNS servers by default, but they’re often slow, unreliable, and track every domain you visit. Independent DNS providers are faster and don’t log your queries.

Best DNS servers in 2026
1. Cloudflare DNS (1.1.1.1) — Fastest & most private
Primary DNS: 1.1.1.1
Secondary DNS: 1.0.0.1
Cloudflare’s 1.1.1.1 is the fastest public DNS resolver in independent tests. They promise to never log your IP address and delete all query logs within 24 hours.
Why use it:
- Consistently the fastest resolver globally
- Strong privacy policy with regular audits
- Built-in malware blocking (optional)
- Supports DNS-over-HTTPS and DNS-over-TLS
Best for: Anyone who wants speed + privacy without compromise.
2. Google Public DNS (8.8.8.8) — Fast & reliable
Primary DNS: 8.8.8.8
Secondary DNS: 8.8.4.4
Google’s DNS is fast, stable, and works everywhere. The downside? Google logs some query data for 24-48 hours for “security and diagnostics.”
Why use it:
- Extremely reliable with global coverage
- Fast response times
- Good for troubleshooting (some ISPs block custom DNS, but rarely Google’s)
Best for: Speed and reliability when privacy isn’t your top priority.
3. Quad9 DNS (9.9.9.9) — Security-focused
Primary DNS: 9.9.9.9
Secondary DNS: 149.112.112.112
Quad9 automatically blocks access to malicious domains. It’s run by a nonprofit and doesn’t log your IP address.
Why use it:
- Blocks phishing, malware, and exploit domains automatically
- No IP logging
- Based in Switzerland (strong privacy laws)
Best for: Security-conscious users who want automatic threat protection.
Boost your security further: Get Bitdefender Antivirus for complete device protection.
4. OpenDNS Home (208.67.222.222) — Parental controls
Primary DNS: 208.67.222.222
Secondary DNS: 208.67.220.220
OpenDNS (now owned by Cisco) offers customizable filtering. You can block adult content, gambling sites, or specific categories.
Why use it:
- Free parental controls and content filtering
- Blocks phishing sites
- Customizable via web dashboard
Best for: Families who want to filter content at the network level.
5. AdGuard DNS (94.140.14.14) — Blocks ads & trackers
Primary DNS: 94.140.14.14
Secondary DNS: 94.140.15.15
AdGuard’s DNS blocks ads, tracking domains, and malware at the DNS level before they even load in your browser.
Why use it:
- Blocks ads across all apps and devices
- Stops tracking scripts
- No IP logging
Best for: Users who want network-wide ad blocking without installing extensions.
How to change your DNS server
On Windows:
- Open Control Panel → Network and Sharing Center
- Click your network connection → Properties
- Select Internet Protocol Version 4 (TCP/IPv4) → Properties
- Choose “Use the following DNS server addresses”
- Enter your preferred DNS (e.g., 1.1.1.1) and alternate DNS (e.g., 1.0.0.1)
- Click OK
On macOS:
- Go to System Preferences → Network
- Select your active connection → Advanced
- Go to the DNS tab
- Click + and add 1.1.1.1, then add 1.0.0.1
- Click OK → Apply
On your router (covers all devices):
- Log into your router (usually 192.168.1.1 or 192.168.0.1)
- Find DNS settings (often under “Internet” or “WAN”)
- Replace existing DNS with your preferred server
- Save and restart the router
Tip: Use our DNS Checker tool to verify your new DNS is working.
Should you use your VPN’s DNS?
If you use a VPN, your traffic is already encrypted and routed through the VPN’s DNS servers. You don’t need to manually change DNS settings.
In fact, manually setting DNS while using a VPN can cause DNS leaks where your real queries bypass the VPN tunnel.
Check for leaks: Use our VPN Leak Test to see if your DNS is exposed.
Need a VPN? We recommend:
- PureVPN — Fast servers, strong encryption, no-logs policy
- IPVanish — Unlimited connections, great for families

Does changing DNS really speed up browsing?
Yes, but the effect varies. DNS lookups happen every time you visit a new domain, but most results are cached locally after the first visit.
You’ll notice the biggest improvement on:
- First-time visits to websites
- Pages with lots of external resources (ads, scripts, fonts)
- Unreliable ISP DNS servers (some are really slow)
Switching from a slow ISP DNS to Cloudflare can reduce lookup times from 50ms to 10ms — a noticeable improvement on content-heavy pages.
Can your ISP block custom DNS?
Some ISPs redirect all DNS traffic to their own servers, even if you configure a different DNS. This is called DNS hijacking.
To bypass this:
- Use DNS-over-HTTPS (DoH) or DNS-over-TLS (DoT) — these encrypt DNS queries and prevent ISP interception
- Or use a VPN, which tunnels all traffic (including DNS) through an encrypted connection

Frequently Asked Questions
What is the fastest DNS server?
Cloudflare’s 1.1.1.1 is consistently the fastest in independent benchmarks, followed by Google’s 8.8.8.8. Speed varies by location, so test both.
Does DNS affect internet speed?
DNS affects how fast websites start loading, not your overall download speed. A faster DNS reduces the delay before a page begins to load, but doesn’t increase bandwidth.
Can changing DNS improve gaming ping?
No. DNS only resolves domain names; it doesn’t affect your connection to game servers once the IP is known. For better gaming performance, reduce network latency through wired connections or better routing.
Is it safe to use public DNS servers?
Yes, if you use reputable providers like Cloudflare, Google, or Quad9. Avoid unknown DNS servers — some inject ads or redirect traffic to malicious sites.
Should I use DNS-over-HTTPS?
Yes. DoH encrypts your DNS queries, preventing ISPs and network admins from seeing which sites you visit. Most modern browsers support it. Learn how to enable DoH.
Can DNS servers see what I’m doing online?
DNS servers see which domains you visit (e.g., “reddit.com”), but not the specific pages or content (e.g., “/r/privacy/comments/abc123”). For full privacy, use a VPN: Get PureVPN.
Final recommendation
For most people: Use Cloudflare (1.1.1.1). It’s fast, private, and easy to remember.
For families: Use OpenDNS (208.67.222.222) for built-in content filtering.
For security nerds: Use Quad9 (9.9.9.9) for automatic malware blocking.
For VPN users: Stick with your VPN’s DNS to avoid leaks. Test it with our VPN Leak Test tool.
Switching DNS takes one minute and improves your browsing immediately. There’s no reason to keep using your ISP’s slow, privacy-invading default.
