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.
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:
Example: Google's 8.8.8.8 or Cloudflare's 1.1.1.1.
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.

Tip: Test each provider using your location — the fastest DNS may vary based on your region and latency.
| 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 |
Using primary and secondary DNS servers ensures redundancy:
Pro tip: Some advanced routers support DNS fallback lists and load-balancing between resolvers.
1.1.1.1 / 8.8.8.8).ipconfig /flushdns
System Preferences → Network → Advanced → DNS tab
Edit /etc/resolv.conf or set via NetworkManager GUI.
Use Private DNS → set 1dot1dot1dot1.cloudflare-dns.com for DoT.
Or configure Wi-Fi DNS manually under network settings.
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.

| Speed | Cloudflare (1.1.1.1) + Google (8.8.8.8) |
| Privacy | Quad9 + AdGuard |
| Family Safe | CleanBrowsing + OpenDNS FamilyShield |
| Developers / Testing | Google + Cloudflare + your own resolver |
| ISPs / Enterprises | PowerDNS Recursor + Unbound combo |
Cloudflare (1.1.1.1) and Google (8.8.8.8) are typically the fastest worldwide, depending on region.
Yes. Modern OSes and routers can handle multiple DNS entries for redundancy and performance.
No. It only affects how quickly your system resolves domains.
Yes, but choose reputable providers that support DNSSEC and don't log data unnecessarily.
Sometimes—if restrictions are based on DNS filtering, but not if blocked at IP/firewall level.
