Public DNS Servers
In . there are restrictions on the public DNS resolution (eg 8.8.8.8), and the ISPs LDNS has whitelist restrictions, allowing only the IPSs own users to access.

Why DNS performance matters in
DNS resolution speed and reliability directly affect website loading time, application responsiveness, and overall internet experience.
- Faster DNS responses reduce page load latency
- Reliable resolvers improve connection stability
- Local DNS servers often provide better routing results
- Redundant DNS options enhance fault tolerance
Data sources and testing methodology
The DNS server data on Aleiwa is collected and maintained through a combination of public datasets and active network probing.
- Public DNS IP datasets and operator disclosures
- Regular availability checks using standard DNS queries
- Geolocation and ASN mapping based on IP intelligence data
- Ongoing validation to remove inactive or unreachable servers
DNS servers marked as available have responded successfully during the most recent checks.
Common use cases
- Improving DNS resolution speed for local users
- Testing ISP DNS behavior and routing policies
- Network diagnostics and troubleshooting
- Academic and infrastructure research
