DNS Server List — Fastest & Most Reliable Public DNS Providers (2025)
DNS servers control how quickly and securely you connect to websites. By changing your DNS provider, you can increase speed, improve privacy, and bypass local network restrictions.
Below is the ultimate DNS server list for 2025, including public and free DNS providers for both IPv4 and IPv6 networks.
What Is a Public DNS Server?
A public DNS server is a resolver that anyone can use instead of the one assigned by their Internet Service Provider (ISP).
Public DNS servers often provide:
- Faster lookup speeds
- Better uptime
- Enhanced privacy (no ISP tracking)
- Malware and phishing protection
Example: Google's 8.8.8.8 or Cloudflare's 1.1.1.1.
Why Change Your DNS Server?
Changing your DNS can improve:
Some DNS servers resolve domains faster based on Anycast routing.
Many public servers don't log user queries.
Services like Quad9 block malicious domains.
Avoid outages from your ISP's default DNS.
Sometimes helps bypass regional blocks or incorrect routing.

DNS Servers for Privacy and Security
| Provider | Focus | Logs Data? | DNSSEC | DoH/DoT Support |
|---|---|---|---|---|
| Cloudflare | Privacy | No logs (purged daily) | Yes | Yes |
| Quad9 | Security | Minimal logs | Yes | Yes |
| AdGuard | Privacy + Ad blocking | Minimal logs | Yes | Yes |
| Speed | Anonymized logs (24–48h) | Yes | Yes | |
| OpenDNS | Security + Filtering | Keeps logs (for dashboard) | Yes | No |
Why Use Multiple DNS Servers?
Using primary and secondary DNS servers ensures redundancy:
- If one fails, your system automatically queries the next.
- You can mix providers (e.g., Google + Cloudflare) to balance performance and privacy.
- For enterprises, having multiple resolvers prevents regional outages.
Pro tip: Some advanced routers support DNS fallback lists and load-balancing between resolvers.
How to Change Your DNS Server
Windows
- Open Network & Internet Settings → Change adapter options.
- Right-click your connection → Properties.
- Select "Internet Protocol Version 4 (TCP/IPv4)".
- Click "Use the following DNS server addresses" and enter preferred addresses (e.g.,
1.1.1.1/8.8.8.8). - Click OK and flush cache:
ipconfig /flushdns
macOS
System Preferences → Network → Advanced → DNS tab
Linux
Edit /etc/resolv.conf or set via NetworkManager GUI.
Android / iOS
Use Private DNS → set 1dot1dot1dot1.cloudflare-dns.com for DoT.
Or configure Wi-Fi DNS manually under network settings.
How Changing DNS Improves Internet Quality
Queries reach nearest Anycast node.
DNS resolution happens faster.
Some ISPs delay or intercept DNS queries.
Public servers may resolve blocked or misconfigured domains correctly.
Multi-region redundancy ensures uptime.

Frequently Asked Questions
1. Which is the fastest DNS server?
Cloudflare (1.1.1.1) and Google (8.8.8.8) are typically the fastest worldwide, depending on region.
2. Can I use more than two DNS servers?
Yes. Modern OSes and routers can handle multiple DNS entries for redundancy and performance.
3. Does changing DNS affect my IP or internet plan?
No. It only affects how quickly your system resolves domains.
4. Are public DNS servers safe?
Yes, but choose reputable providers that support DNSSEC and don't log data unnecessarily.
5. Will DNS changes unblock websites?
Sometimes—if restrictions are based on DNS filtering, but not if blocked at IP/firewall level.
