Switching DNS When Binance is Slow: Cloudflare, 114, Google Tested

DocBit Notes Editorial · · 12 min

If Binance web pages open slowly or market charts lag, part of the reason might be slow default DNS resolution. This note tests the performance of mainstream public DNS providers and provides steps to switch. To log in directly, open the Binance Official Website; to download the app, use the Binance Official App; for iPhone installation, refer to the iOS installation tutorial.

Tested DNS Providers

Test environment: Shanghai home broadband 100 Mbps, testing DNS resolution latency for the main Binance domain binance.com and binance.info.

DNS Primary IP Secondary IP binance Latency binance.info Latency
Cloudflare 1.1.1.1 1.0.0.1 12 ms 18 ms
Google 8.8.8.8 8.8.4.4 18 ms 22 ms
Quad9 9.9.9.9 149.112.112.112 25 ms 30 ms
Ali 223.5.5.5 223.6.6.6 8 ms 12 ms
114DNS 114.114.114.114 114.114.115.115 6 ms Resolution Failed
Tencent 119.29.29.29 - 9 ms 15 ms
ISP Default Varies by ISP - 5 ms Occasional Pollution

Ali DNS and the ISP default are both very fast, but 114DNS occasionally fails to resolve binance.info, which may be related to pollution strategies.

Recommended DNS

Recommendations based on needs:

Requirement Recommendation
Speed Priority Ali 223.5.5.5
Stable Cross-Border Domains Cloudflare 1.1.1.1
Security Filtering Quad9 9.9.9.9
Compatibility Google 8.8.8.8
Not Recommended 114DNS (Abnormal resolution for some overseas domains)

Switching DNS on Windows

Full steps:

  1. Control Panel → Network and Sharing Center
  2. Click the "Connections" link for your active network.
  3. "Properties" → Double-click "Internet Protocol Version 4 (TCP/IPv4)".
  4. Select "Use the following DNS server addresses".
  5. Preferred DNS server: 1.1.1.1
  6. Alternate DNS server: 8.8.8.8
  7. "OK" → "OK"
  8. Open Command Prompt and run ipconfig /flushdns to flush the cache.

The switch takes effect immediately.

Switching DNS on macOS

  1. System Settings → Network
  2. Select your current Wi-Fi or Ethernet → "Details..."
  3. "DNS" tab
  4. Click the + button to add 1.1.1.1 and 8.8.8.8.
  5. Drag to reorder, moving the new DNS to the top.
  6. OK

Switching DNS on Android

Android 9+ offers "Private DNS":

  • Settings → Network & internet → Private DNS
  • Select "Private DNS provider hostname"
  • Enter: one.one.one.one (Cloudflare) or dns.google (Google)
  • Save

Private DNS uses DoT (DNS over TLS), which is more secure.

The path varies on some custom ROMs:

  • MIUI: Settings → Dual SIM & Mobile Network → Private DNS
  • HarmonyOS: Settings → Mobile Network → Private DNS
  • ColorOS: Settings → Wi-Fi → Advanced Settings → Private DNS

Switching DNS on iOS

  1. Settings → Wi-Fi → Tap the "i" icon next to your current Wi-Fi.
  2. "Configure DNS" → "Manual"
  3. Delete existing DNS servers.
  4. Add new DNS servers (1.1.1.1, 8.8.8.8).
  5. Save

On iOS, DNS settings only apply to the current Wi-Fi network; each Wi-Fi must be configured separately.

Switching DNS at the Router Level

A more thorough method is to switch at the router level, so all connected devices use the new DNS:

  1. Enter your router's admin panel via a browser (usually 192.168.1.1 or 192.168.0.1).
  2. Find "DHCP Server" or "Network Settings".
  3. Enter 1.1.1.1 and 8.8.8.8 for the DNS servers.
  4. Save and reboot.

Afterward, all devices at home will automatically use the new DNS.

DoH / DoT Encrypted DNS

Standard DNS queries are sent in plaintext and can be hijacked. Encrypted DNS options:

Protocol Providers
DoH (DNS over HTTPS) Cloudflare, Google, Quad9
DoT (DNS over TLS) Same as above

DoH is supported at the browser level (can be enabled in Firefox / Chrome settings). DoT is supported at the OS level (Android Private DNS).

Encrypted DNS prevents DNS queries from being viewed or tampered with by intermediate devices.

Side Effects of Switching DNS

Possible side effects:

  • Slower resolution for some domestic CDNs (public DNS doesn't know your local node).
  • Resolution failures for certain corporate intranet domains (company DNS includes internal domains).
  • Video sites may route through distant CDNs.

For the first two issues: you can keep your ISP's DNS as a backup.

Flushing DNS Cache

Flush the cache immediately after switching DNS:

  • Windows: ipconfig /flushdns
  • macOS: sudo killall -HUP mDNSResponder
  • Linux: resolvectl flush-caches (or systemd-resolve --flush-caches)
  • Android: Toggle Airplane mode on and off.
  • iOS: Toggle Airplane mode on and off.

After clearing, accessing binance.com will query using the new DNS.

Long-Term Usage Recommendations

Scenario DNS Configuration
Primary Home Use Ali + Cloudflare backup
Public Wi-Fi Cloudflare Private DNS
Corporate Network Company DNS (as per IT requirements)
Traveling Abroad Cloudflare

FAQ

Q: Will switching DNS slow down my internet speed? A: DNS only affects domain resolution (once before each connection) and does not affect subsequent data transfer speeds.

Q: Can DNS bypass blocks? A: DNS only resolves "parsing" and cannot bypass IP blocks.

Q: Which is better, DoH or DoT? A: DoH has better compatibility (uses port 443), while DoT is more purpose-built. For daily use, DoH is fine.

Q: Can I use multiple DNS servers at the same time? A: Yes, the system will try them in order. It's recommended to have a primary and a backup from different providers.
