A DNS performance testing IPv4, IPv6, DNS over HTTPS (DoH), DNS over TLS (DoT), and DNS over QUIC (DoQ).

Public Instance:

• https://yadnsb.onrender.com
• https://yadnsb.altendorfme.com

• Node.js 20 or higher
• npm or yarn package manager

1. Clone or download the project files
2. Install dependencies:

npm install

3. Start the server:

npm start

4. Open your browser and navigate to:

http://localhost:3000

1. Select DNS Providers: Choose from the list of pre-configured DNS providers
2. Configure Protocols: Select which DNS protocols to test (IPv4, IPv6, DoH, DoT, DoQ)
3. Set Test Domains: Use preset domains or add custom ones
4. Configure Test Parameters:
   • Interval between requests (seconds)
   • Number of tests per provider
5. Start Benchmark: Click "Start Benchmark" to begin testing

Enter custom domains in the text area, one per line:

example.com
mysite.org
test.net

Filter providers by supported protocols:

• IPv4: Traditional DNS over UDP/TCP
• IPv6: IPv6 DNS resolution
• DoH: DNS over HTTPS (RFC 8484)
• DoT: DNS over TLS (RFC 7858)
• DoQ: DNS over QUIC (RFC 9250) - Note: Limited implementation

Filter by provider type:

• Public: General-purpose DNS servers
• Security: Security-focused with threat blocking
• Family: Family-safe with content filtering
• Privacy: Privacy-focused DNS services

The results table shows:

• Rank: Performance ranking
• Provider: DNS provider name and protocol
• Min/Median/Average/Max: Response time statistics
• Success Rate: Percentage of successful queries
• Tests: Number of successful/total tests

Export test results in two formats:

• JSON: Complete data including raw results and statistics
• CSV: Tabular format suitable for spreadsheet analysis

• GET / - Main application interface
• POST /api/test - Perform single DNS test
• GET /api/providers - Get DNS providers list
• GET /api/health - Health check endpoint
• GET /locales/:lang.json - Language files

• /ws - Real-time test updates and progress

Edit public/data/dns-providers.json:

{
  "name": "Provider Name",
  "category": "Public|Security|Family|Privacy",
  "description": "Provider description",
  "servers": [
    {"type": "IPv4", "address": "1.2.3.4", "port": 53},
    {"type": "DoH", "address": "https://dns.example.com/dns-query", "port": 443}
  ]
}

Run with auto-restart on file changes:

npm run dev

• DoQ Support: Limited implementation due to QUIC protocol complexity
• IPv6 Testing: Requires IPv6 network connectivity
