IKEv2 VPN Android private DNS override
Android offers a feature that lets you specify a "private DNS" server. This is a DNS server that encrypts your DNS queries, preventing your ISP (or anyone else watching your traffic) from seeing the websites you visit. When using a VPN, your VPN provider typically handles DNS requests. However, you can override this and use your own private DNS server even while the VPN is connected. This article focuses on doing this with the IKEv2 VPN protocol on Android.
Why would you want to override your VPN's DNS settings? Here are a few reasons:
Privacy Concerns: You might not fully trust your VPN provider's DNS servers. Using your own private DNS (like Cloudflare's 1.1.1.1 or Google's 8.8.8.8) ensures your DNS queries are handled by a party you trust more.
Customization: You might want to use a DNS server that offers specific features, such as ad blocking or content filtering, that your VPN doesn't provide.
Circumventing Censorship: In rare cases, a VPN might use a DNS server that is subject to censorship. Overriding it can bypass those restrictions.
The method for overriding DNS settings varies depending on the VPN app you use. However, the general steps are usually similar. Here's a simplified guide assuming your VPN app uses Android's built-in IKEv2 support:
Connect to your IKEv2 VPN: Establish a VPN connection through your usual method.
Access Android's Private DNS settings: Go to your Android device's Settings app, then navigate to Network & Internet > Private DNS.
Select "Private DNS provider hostname": Choose this option to manually enter the hostname of your desired DNS server.
Enter the DNS hostname: Type in the hostname (e.g., one.one.one.one for Cloudflare or dns.google for Google Public DNS).
Save your changes: The system should automatically apply the new DNS setting.
Some VPN apps offer granular control over DNS settings within their own interface. Look for these options:
"Allow VPN to override": This setting (if present) lets the VPN app control the DNS server when it's connected. Disable this to ensure your private DNS setting takes precedence.
"Leak Protection": Ensure your VPN app has leak protection enabled. This helps prevent DNS requests from accidentally bypassing the VPN tunnel.
Keep these points in mind:
Testing: After setting up your private DNS, verify it's working correctly. Several websites can check your DNS server (search "DNS leak test").
Performance: Using a private DNS server that's geographically distant can slightly increase latency.
VPN App Compatibility: Not all VPN apps fully support private DNS override. Some may force their own DNS settings regardless.
Privacy is not absolute: While private DNS encrypts your DNS queries, it doesn't make you completely anonymous. Your VPN still sees your IP address and traffic.
