DNS Split Configuration Guide

A detailed guide on how to optimize network access experience through DNS split configuration, including domestic and international DNS server setup guides and split rule settings.

    DNS Split Overview

    DNS split can significantly enhance the network access experience by distributing resolution requests for different domain names to different DNS servers. A reasonable DNS split configuration can:

    • Speed up domain name resolution
    • Improve website access stability
    • Optimize cross-border access experience
    • Avoid DNS pollution issues

    Adguard Private Split Configuration

    Basic Configuration Example

    # Domestic DNS server
223.5.5.5                                    # Ali DNS
2400:3200::1                                 # Ali DNS IPv6
public0.adguardprivate.svc.cluster.local    # Private DNS, mainland upstream

# International DNS server
tls://1.0.0.1                               # Cloudflare DNS
tls://[2606:4700:4700::1001]               # Cloudflare DNS IPv6
public2.adguardprivate.svc.cluster.local    # Private DNS, other upstream

# Split rule example

    Configuration Recommendations

    1. Prioritize nearby DNS servers
    2. Configure both IPv4 and IPv6 DNS
    3. Set up backup DNS for important domains
    4. Regularly update split rules
    5. Monitor DNS response time

    Precautions

    • Record original DNS settings before configuration
    • Avoid using untrusted DNS servers
    • Regularly check if DNS resolution is normal
    • Keep the rule list concise and effective

    By reasonably configuring DNS split, you can significantly enhance the network access experience. It is recommended to choose appropriate DNS servers and split rules based on actual needs.
