🔍 Understanding DNS Leak Tests and Anycast DNS on EDIS Global VPS

When running DNS leak tests like dnsleaktest.com or whoer.net, you may sometimes notice that detected DNS servers are not located in the same country as your VPS.

​

🛡️ Why is this happening?

At EDIS Global, we use fast and secure Anycast DNS servers provided by Cloudflare—specifically 1.1.1.1 and 1.0.0.1—to handle DNS resolution on our VPS.

With Anycast technology, your DNS requests are routed to the closest and fastest available server. This means your DNS traffic might be handled by a server outside your VPS location, even in a neighboring country.

⚠️ This is completely normal and nothing to worry about.

​

✅ Does this affect my VPS geo-location?

No!
The DNS server location does not influence the geographic location of your VPS.
Your VPS IP address is what defines your geo-location, and not where DNS queries are resolved.

​

🔄 Why do test results show different locations?

DNS leak tests show the location of the DNS resolvers that handled your queries (such as Cloudflare’s Anycast nodes), which may differ from your VPS’s actual location. Sometimes the nearest and fastest DNS server may even be across a national border.

​

✅ What is a DNS Leak Test?

A DNS Leak Test checks whether your DNS requests are securely handled or if they accidentally leak outside your protected network, such as:

• To your local internet provider (ISP).
• Outside of your VPN tunnel.

The purpose of the test is to confirm that only the intended DNS servers are used, ensuring your privacy.

​

🧪 How does a DNS Leak Test work?

DNS leak tests, like dnsleaktest.com and whoer.net, ask your device to resolve a series of unique domain names. The test then observes:

• Which DNS servers answered the queries.
• Their IP addresses.
• Their geographic locations.
• The organizations operating them.

​

🔍 What is the difference between Standard and Extended Tests?

​

Standard Test:

• Performs a quick check.
• Detects obvious DNS leaks.
• Recommended for most users.

​

Extended Test:

• Runs a more thorough scan.
• Identifies all potential DNS servers.
• Useful for higher privacy needs, but usually not necessary.

​

⚙️ Can I change the DNS servers on my VPS?

Yes!
If you want to influence the test results or use different DNS resolvers, you can:

• Switch to Google DNS (8.8.8.8, 8.8.4.4), Quad9 (9.9.9.9), OpenDNS (208.67.222.222), or others.
• Configure your own custom DNS servers on your VPS.

​

🔑 But remember:

The goal of DNS leak tests is to detect if DNS requests are leaking outside your secure environment (like a VPN), not to determine geo-location accuracy.

​

📝 Summary

• EDIS Global uses Cloudflare Anycast DNS (1.1.1.1 and 1.0.0.1) to ensure fast, secure DNS resolution.
• DNS leak test results showing locations different from your VPS location are expected.
• DNS server location does NOT affect your VPS’s IP geo-location.
• You can change DNS resolvers if you want to adjust test results.
• The purpose of a DNS Leak Test is privacy and security, ensuring DNS requests do not escape your secure environment.
