In recent years, domestic home broadband has enabled IPv6 by default, but some users have found that certain overseas services slow down after it's turned on. How does Binance perform on IPv6? This note will test it out. For direct login, please open the Binance Official Website; to download the APP, go to Binance Official App; for iPhone installation, see the iOS Installation Tutorial.
Binance Support on IPv6
The current IPv6 support status of Binance main domains:
| Domain | A Record | AAAA Record (IPv6) |
|---|---|---|
| binance.com | Yes | Yes (Cloudflare) |
| binance.info | Yes | Yes |
| binance.bz | Yes | Yes |
| api.binance.com | Yes | Yes |
| www.binance.com | Yes | Yes |
Binance fully supports IPv6 (Cloudflare enables v6 by default).
IPv4 and IPv6 Preference Policy
When both protocols are available, the operating system prioritizes IPv6 according to RFC 6724:
- DNS returns both A and AAAA simultaneously
- The system prioritizes trying AAAA (IPv6)
- If it fails, it falls back to A (IPv4)
The vast majority of users don't need to worry about this. However, in some scenarios, an IPv6 failure can lead to latency:
- ISP's IPv6 outbound gateway failure
- Incomplete IPv6 configuration on the home router
- The system has been assigned an IPv6 address, but the routing is unreachable
Real-world Test Comparison
I tested two sets of data using a Win11 computer:
| Mode | First-screen Load | API Latency |
|---|---|---|
| IPv6 Priority | 2.6 seconds | 80 ms |
| IPv4 Only | 2.4 seconds | 75 ms |
The difference is very small (< 5%) and can be ignored. But if your ISP's IPv6 is unstable, the gap may be noticeable.
How to Determine if IPv6 is Normal
Troubleshooting:
- Visit test-ipv6.com in your browser to see the score
- Full 10/10 → Perfect
- Some items fail → Incomplete IPv6
- Connection timeout → IPv6 routing issue
If your IPv6 test score is lower than 8, accessing Binance may be slower.
How to Disable IPv6
If you confirm that IPv6 is slowing down Binance:
Windows:
- Control Panel → Network and Sharing Center → Adapter Properties
- Uncheck "Internet Protocol Version 6 (TCP/IPv6)"
- OK
macOS:
- System Settings → Network → Adapter → Details → TCP/IP
- Set Configure IPv6 to "Off"
Android / iOS:
- There is no simple option to turn off IPv6 at the system level
- It can only be disabled at the WiFi router level
Router:
- Find "IPv6 Settings" in the backend
- Just turn it off
- All devices in the home will no longer use IPv6
Considerations Before Fully Disabling
Side effects of disabling IPv6:
- Some intranet services may depend on IPv6 (home NAS)
- Certain IPv6-priority services become slower (e.g., some YouTube nodes)
- ISPs are retreating from IPv4; in the long run, IPv6 is the trend
Only disable it when you confirm that IPv6 is causing slowdowns.
Special Environments with DNS64 and NAT64
In some IPv6-only networks (such as IPv6-only mobile networks):
- IPv4 addresses are mapped to IPv6 via DNS64
- Traffic is translated via NAT64
- Users won't notice the difference, but the latency is slightly higher
Mainland Chinese home broadband is usually dual-stack (IPv4 + IPv6), not pure v6, so it is unaffected.
Advantages of IPv6
Although performance may vary, IPv6 has long-term benefits:
- No longer facing IPv4 address exhaustion
- Better routing (end-to-end connection, no NAT)
- Lower latency (in some scenarios)
- Built-in IPSec support
Binance may further optimize the IPv6 experience in the future.
IPv6 on Mobile Data
Domestic carriers:
- China Mobile 4G/5G: Dual-stack by default
- China Telecom 5G: Dual-stack by default
- China Unicom 5G: Dual-stack or pure v6
Accessing Binance under mobile data usually yields a good IPv6 experience.
Browser Priority Settings
Some browsers allow adjustments:
- Firefox: about:config → network.http.fast-fallback-to-IPv4
- Chrome: Default behavior, no settings
- Safari: Follows the system
Regular users can just use the default settings.
Router IPv6 Configuration
If a home router's IPv6 configuration is incomplete:
- Devices can get an IPv6 address but cannot access the internet
- Browser DNS returns AAAA but access fails
- The symptom is "Binance web page spinning continuously"
Solution: Log in to the router's backend to disable IPv6 or reconfigure the IPv6 firewall.
Long-term Recommendations
For the vast majority of home users:
- Maintain dual-stack (IPv4 + IPv6)
- Keep router firmware updated to the latest version
- Do not proactively disable IPv6 unless there is an issue
- Only consider it when experiencing slow access to Binance
FAQ
Q: Can Binance be used under a pure IPv6 network? A: Yes, Binance offers full-stack support for IPv6.
Q: Is IPv6 more secure than IPv4? A: They are similar at the protocol level, but IPv6 defaults to no NAT and relies on firewalls.
Q: Will disabling IPv6 affect other APPs? A: It might. Confirm the issue before disabling it.
Q: Which version does the APP use? A: The APP uses the system protocol stack, consistent with the browser.
