All DNS server data in this repository is sourced from dnsdirectory.com's validated testing infrastructure. The data goes through the following validation:

1. Online Status: Only servers that respond to DNS queries are included
2. Response Validation: Servers must return valid DNS responses
3. Continuous Monitoring: Uptime is tracked over 24h, 30d, 90d, and 1y periods

Servers marked as "trusted" have been manually verified to belong to known, reputable DNS providers such as:

• Google Public DNS
• Cloudflare DNS
• Quad9
• OpenDNS
• AdGuard DNS

When using DNS servers from this repository:

• For security research: Use the trusted.txt list for more reliable results
• For production: Verify servers independently before deployment
• For testing: Any server list is suitable for development/testing purposes

While we strive to maintain accurate data, we cannot guarantee the security or reliability of any individual DNS server. Use this data at your own risk and always verify servers for your specific use case.
