How To Avoid DNS Blocking

Avoiding DNS blocking means accessing websites or services that have been restricted at the DNS (Domain Name System) level—usually by ISPs, governments, schools, or workplaces. While bypassing DNS blocks may violate local laws or network policies, here’s how it’s technically done:

🛡️ How To Avoid DNS Blocking (For Educational Purposes)

✅ 1. Change Your DNS Server

Instead of using your ISP’s default DNS, switch to a public DNS that doesn’t apply local restrictions.

Popular Unblocked DNS Providers:

Google DNS – 8.8.8.8 and 8.8.4.4
Cloudflare DNS – 1.1.1.1 and 1.0.0.1
OpenDNS – 208.67.222.222 and 208.67.220.220

📱 You can change DNS on your device (computer, phone) or router to affect all connected devices.

✅ 2. Use a VPN (Virtual Private Network)

A VPN encrypts your internet traffic and routes it through a server in another location, bypassing DNS and IP-based blocks.

Choose reputable VPNs like ProtonVPN, NordVPN, Mullvad, ExpressVPN.
Free VPNs may be less secure or more easily blocked.

✅ 3. Use DNS-over-HTTPS (DoH) or DNS-over-TLS (DoT)

These encrypt DNS requests, hiding them from your ISP.

Firefox and Chrome support DoH natively.
Apps like Cloudflare’s 1.1.1.1 with Warp or NextDNS offer encrypted DNS on mobile.

✅ 4. Access the Site by IP Address (If Not IP-Blocked)

Sometimes the domain is blocked, but the IP isn’t.

Use tools like ping domain.com or online DNS lookups to get the IP.
May not work if the server hosts multiple domains (due to SNI in HTTPS).

✅ 5. Use a Proxy Server or Tor

Web proxies let you access blocked domains via another server.
Tor Browser routes traffic through multiple layers for anonymity and unblocking, though it’s slower.

⚠️ Legal and Ethical Notes:

DNS blocking is often used to enforce copyright law, national censorship, or organizational policies.
Circumventing blocks may violate laws or terms of service, especially in countries with strict internet regulations.
Proceed responsibly and at your own risk.
