To make Windows prioritize IPv6 for all network connections (including ping, browsers, games, etc.), follow these steps:

Alternatively, use the one-click priority boost script

📌 Core Steps (Recommended)

1. Modify IPv6 Prefix Policies (Enforce Priority)

Run CMD/PowerShell as Administrator and execute:

netsh interface ipv6 set prefixpolicy ::/0 100 0 persistent  
netsh interface ipv6 set prefixpolicy ::ffff:0:0/96 40 1 persistent  
netsh interface ipv6 set global randomizeidentifiers=disabled  
netsh interface ipv6 set global randomizeidentifiers=enabled  

• ::/0: Represents all IPv6 addresses. Set priority to 100 (highest).
• ::ffff:0:0/96: Represents IPv4-mapped addresses. Set priority to 40 (lower than IPv6).
• Lines 3-4 reload IPv6 configurations to apply changes immediately.

2. Verify Configuration

netsh interface ipv6 show prefixpolicies  

• Check the output to ensure ::/0 has a Precedence of 100 and appears before ::ffff:0:0/96.

3. Validate Connectivity

1. Open Command Prompt (Win + R → cmd → Enter).
2. Run:

    ping api.spotify.com  
    ping accounts.spotify.com  
   

   If IPv6 responses are received without the -6 flag, the configuration is successful.

🔍 Additional Optimization (Optional)

4. Check DNS Resolution Order

nslookup spotify.com  

• If IPv6 (AAAA records) are listed before IPv4 (A records), DNS prioritization is active.

5. Test ping and curl

ping api.spotify.com          # Should return IPv6 addresses  
curl -v https://api.spotify.com  # Should use IPv6 connections

❓ Frequently Asked Questions

Q1: Why does ping still use IPv4?

• Possible reasons:
  • The target website lacks IPv6 (AAAA records).
  • Local firewall/ISP blocks IPv6 ICMP requests.
  • DNS cache is outdated (try ipconfig /flushdns).

Q2: How to restore default settings?

netsh interface ipv6 reset  

• All settings revert to default after a system reboot.
• You must reapply configurations after rebooting.
