1.What is VPN DNS?

When using a VPN, DNS (Domain Name System) requests can impact your privacy and security. Here’s what you need to know about VPN DNS:

• When you connect to a VPN, your internet traffic is routed through the VPN server, including DNS queries (which translate domain names like google.com into IP addresses).
• Ideally, your VPN should handle DNS requests to prevent leaks.

DNS Leaks: A Major Privacy Risk

• A DNS leak occurs when your device bypasses the VPN and sends DNS requests to your ISP’s (or another third-party’s) DNS servers.
• This exposes your browsing activity, even if you’re using a VPN.

How VPNs Handle DNS

• VPN-Controlled DNS: Most reputable VPNs route DNS queries through their own encrypted servers, preventing leaks.
• Third-Party DNS: Some VPNs allow custom DNS (e.g., Cloudflare, Google DNS), but this may reduce privacy.
• No-Log DNS: Trustworthy VPNs use no-log DNS to avoid tracking your queries.

How to Prevent DNS Leaks

• Use a VPN with Built-in DNS Protection (e.g., NordVPN, ProtonVPN, Mullvad).
• Enable "DNS Leak Protection" in your VPN settings.
• Check for Leaks using sites like DNSLeakTest.com.
• Use VPN’s "Kill Switch" to block traffic if the VPN disconnects.
• Manually Configure DNS (if needed) to the VPN provider’s servers.

Split Tunneling & DNS

• If you use split tunneling (allowing some apps outside the VPN), ensure DNS requests from those apps don’t leak.

Alternative: Encrypted DNS (DoH/DoT)

• Some users combine VPNs with DNS-over-HTTPS (DoH) or DNS-over-TLS (DoT) for extra security.
• However, this may conflict with the VPN’s DNS, so test for leaks.

Final Tips

• Always choose a no-logs VPN with private DNS.
• Avoid free VPNs (they often log DNS queries).
• Regularly test for leaks.
