What to Do If Binance DNS is Polluted? Which DNS is Most Stable

Updated on 2026-04-12 · 16 minOfficial Site

The fastest solution when the Binance official site DNS is polluted is to change your system DNS to 1.1.1.1 (Cloudflare) or 8.8.8.8 (Google), taking effect in 3 minutes. After the change, binance.com will load normally in the vast majority of cases. If you need to install the APP, download it directly from the Binance Official App (the APP has built-in DNS and doesn't rely on system settings). You can access the account registration portal at the Binance Official Site, and see the Download Center for iOS installation. This article outlines the DNS change steps for Windows / macOS / Android / iOS respectively.

What is DNS Pollution

DNS is a service that translates domain names (binance.com) into IP addresses (like 13.34.74.99). Normally, when you enter binance.com, the DNS server tells your browser the IP of the Binance server, and the browser goes to that IP to retrieve data.

DNS pollution means the DNS server returns the wrong IP. Your browser goes to the wrong address and naturally cannot connect to Binance. Some ISPs in mainland China pollute DNS for sensitive domains like crypto exchanges, commonly returning:

  • 0.0.0.0 (Invalid address)
  • 127.0.0.1 (Localhost address)
  • A random irrelevant IP in China (sometimes even jumping to an ad page)

How to check if you're currently polluted:

  • Windows: nslookup binance.com
  • macOS / Linux: dig binance.com
  • Online Tools: dnschecker.org → Enter binance.com and view global resolution results

Normally, binance.com should resolve to IPs belonging to AWS CloudFront or Cloudflare (multiple IPs, located in Singapore/Tokyo/US West, etc.).

Recommended DNS List

DNS Provider Primary DNS Secondary DNS Features
Cloudflare 1.1.1.1 1.0.0.1 Fastest globally, good privacy
Google 8.8.8.8 8.8.4.4 Stable, many global nodes
Quad9 9.9.9.9 149.112.112.112 Security filtering, blocks phishing
OpenDNS 208.67.222.222 208.67.220.220 Owned by Cisco, enterprise-grade
AdGuard DNS 94.140.14.14 94.140.15.15 Built-in ad blocking

Recommended Order: Cloudflare > Google > Quad9. Cloudflare has the lowest latency in mainland China (typically 30-80ms), with Google in second (80-150ms).

Changing DNS on Windows

Windows 10 / 11

  1. Right-click the Start menu → Settings → Network & internet
  2. Select your current network connection (Wi-Fi or Ethernet)
  3. Scroll to the bottom → DNS server assignment → Click "Edit"
  4. Change "Automatic (DHCP)" to "Manual"
  5. Toggle the "IPv4" switch to On
  6. Preferred DNS: 1.1.1.1
  7. Alternate DNS: 8.8.8.8
  8. Save

Or via the classic Control Panel:

  1. Control Panel → Network and Sharing Center → Change adapter settings
  2. Right-click your current network connection → Properties
  3. Double-click "Internet Protocol Version 4 (TCP/IPv4)"
  4. Select "Use the following DNS server addresses"
  5. Enter 1.1.1.1 / 8.8.8.8
  6. OK → Restart the network

Flush DNS Cache

After modifying, run in PowerShell:

ipconfig /flushdns

It takes effect once it says "Successfully flushed the DNS Resolver Cache".

Changing DNS on macOS

  1. System Settings → Network
  2. Select your current connection (Wi-Fi or Ethernet)
  3. Click "Details..."
  4. Select "DNS" on the left
  5. Click "+" to add: 1.1.1.1, then click "+" again to add: 8.8.8.8
  6. Delete any existing ones (if any)
  7. Click OK

Flush DNS cache: run in Terminal

sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder

Enter your login password to apply.

Changing DNS on Android

Method A: Single Wi-Fi Modification

  1. Settings → Wi-Fi → Long press your current network connection
  2. "Modify network" or "Advanced options"
  3. Change IP settings to "Static"
  4. Scroll to the DNS1 / DNS2 fields
  5. DNS 1: 1.1.1.1
  6. DNS 2: 8.8.8.8
  7. Save

Method B: Private DNS (Android 9+)

  1. Settings → Network & internet → Private DNS
  2. Select "Private DNS provider hostname"
  3. Enter: one.one.one.one (Cloudflare's DoT service)
  4. Save

Private DNS is encrypted and much harder to hijack than plain text DNS.

Changing DNS on iOS

iPhone / iPad

  1. Settings → Wi-Fi
  2. Tap the ⓘ info button next to your current network
  3. Scroll to find "Configure DNS"
  4. Select "Manual"
  5. Delete any existing DNS servers
  6. Add: 1.1.1.1
  7. Add: 8.8.8.8
  8. Save

Global DNS over HTTPS (More Secure)

Install the "1.1.1.1" app from the App Store (official Cloudflare app). Once enabled, it replaces global DNS with the DoH protocol, covering both Wi-Fi and cellular data. It's free and requires zero configuration.

Verification After Changing

Check if the DNS change took effect:

  1. Command Line Verification:

    • Windows: nslookup binance.com 1.1.1.1
    • macOS / Linux: dig binance.com @1.1.1.1
    • It should return multiple CloudFront or Cloudflare IPs

  2. Browser Verification: Visit binance.com; if it opens normally, DNS resolution was successful.

  3. Leak Test: Visit dnsleaktest.com, run the Standard Test, and the results should show Cloudflare or Google servers rather than your ISP's.

Unified Router-Level Modification (Recommended)

If multiple devices in your home need DNS changes, changing the router DNS is a one-and-done solution:

  1. Enter your router's management address in your browser (usually 192.168.1.1 or 192.168.0.1)
  2. Log into the admin backend
  3. Find the WAN settings or DHCP settings
  4. Change the DNS servers to 1.1.1.1 / 8.8.8.8
  5. Save and restart

After that, all devices connecting to this Wi-Fi will automatically use the new DNS without needing individual adjustments.

Still Cannot Open After Changing DNS

If binance.com still won't open after modifying your DNS, follow this sequence:

  1. DNS Cache Not Flushed: Run the flushdns command or restart your network
  2. Browser DNS over HTTPS Overriding System Settings: Turn off "Secure DNS" in browser settings or change it to the identical DNS
  3. VPN/Proxy Software Interference: Temporarily close all proxy-type software
  4. ISP IP Range Throttling: Switch to 4G cellular data or try a different ISP
  5. Binance Server Outage (extremely rare): Check the official Binance Twitter for announcements

Frequently Asked Questions

Q: Can 1.1.1.1 be used in China? A: Yes. Cloudflare's response time in mainland China is actually faster than 8.8.8.8 (30-80ms vs 80-150ms), making it the preferred choice.

Q: Will changing DNS affect my access to other websites? A: No. 1.1.1.1 / 8.8.8.8 are global public DNS servers that resolve all domains normally; accessing other sites might even be faster.

Q: Can I use domestic DNS like 114DNS? A: No. Domestic DNS (114.114.114.114, Ali DNS, Tencent DNS), while fast, are equally subject to pollution for crypto exchange domains. You must use overseas public DNS like Cloudflare or Google.

Q: Do I need to change DNS when switching to cellular data? A: No. Cellular network default DNS is usually fine; DNS pollution mainly affects home broadband Wi-Fi.

Q: I changed the DNS on Mac but Safari still won't open binance.com? A: Safari has its own intelligent DNS cache. Try restarting Safari or clearing your browser cache.

Summary

Binance DNS pollution can be solved as fast as 3 minutes: Change your system DNS to 1.1.1.1 (Cloudflare) + 8.8.8.8 (Google), and flush your DNS cache. Windows, macOS, Android, and iOS all have simple modification menus, while a unified router-level change is the most convenient. If binance.com still won't open after changing DNS, the most stable backup plan is to directly use the official Binance APP or desktop client, which are insensitive to system DNS settings.
