Private DNS and Preventing DNS Leaks
DNS leaks can expose your browsing history even when using a VPN. Shieldeum's private DNS prevents this.
What Is DNS?
The Domain Name System translates website names (like shieldeum.com) into IP addresses that computers understand. Every time you visit a website, your device makes a DNS query. Normally, these queries go to your ISP's DNS servers, which means your ISP can see every website you visit, even if the site itself uses HTTPS.
What Is a DNS Leak?
A DNS leak happens when your device sends DNS queries outside the VPN tunnel, typically to your ISP's default DNS servers. This can expose your browsing activity even though your other traffic is encrypted. DNS leaks are one of the most common VPN privacy issues.
How Shieldeum Prevents Leaks
When you connect to Shieldeum, your device uses a local DNS IP that resolves through the VPN. The DNS server runs directly on the VPN server you are connected to, so your DNS queries never leave the encrypted tunnel.
This approach ensures that:
- Your ISP cannot see which websites you visit
- Third-party DNS providers do not receive your queries
- Your DNS and browsing traffic travel through the same encrypted path
Testing for DNS Leaks
You can verify your DNS is not leaking by visiting a DNS leak test website while connected to Shieldeum. If the results show only Shieldeum's DNS servers (not your ISP's), your connection is leak-free.
