DNS split-horizon routes resolution requests for different domains to distinct DNS servers, greatly improving network access. A well-designed setup can:
Accelerate domain resolution
Increase website stability
Optimize cross-border access
Avoid DNS pollution

Prefer geographically close DNS servers
Configure both IPv4 and IPv6 DNS
Set up backup DNS for critical domains
Update split-horizon rules regularly
Monitor DNS response times
Record original DNS settings before changes
Avoid untrusted DNS servers
Periodically verify DNS resolution
Keep rule lists concise and effective
Proper DNS split-horizon configuration can significantly improve network access. Choose DNS servers and rules according to your actual needs.
