1. Understanding DNS and VPN

DNS is like the phonebook of the internet, translating human-friendly domain names (like www.example.com) into IP addresses that computers use to identify each other on the network.

A VPN creates a secure tunnel between your device and the internet, encrypting your data and masking your IP address. This helps protect your online activities from hackers, ISPs, and other entities.

2. Why Use DNS via VPN?

When you connect to a VPN, your internet traffic is routed through the VPN server. However, if your device uses the default DNS settings provided by your ISP, your DNS queries can still be monitored. Configuring DNS through your VPN ensures that your DNS queries are encrypted and routed through the VPN server, adding an extra layer of security.

Benefits of Using VPN DNS

• Increased Privacy: Prevents your ISP from logging your browsing activities.
• Bypassed Geo-Restrictions: Access content that may be blocked in your region.
• Enhanced Security: Protects against DNS leaks, ensuring that your DNS requests are private.

3. Choosing the Right VPN Provider

Not all VPN providers offer DNS leak protection or customizable DNS settings. When selecting a VPN, consider the following factors:

Feature	Importance
No-Log Policy	Keeps your data private
DNS Leak Protection	Prevents DNS queries from leaking
User-Friendly Interface	Simplifies setup
Reliable Customer Support	Helps with troubleshooting
Fast Speeds	Minimizes lag

Some popular VPN providers with robust DNS features include:

• ExpressVPN
• NordVPN
• Surfshark
• CyberGhost

4. Step-by-Step Guide to Setting Up DNS via VPN

Step 1: Choose a VPN Service

Select a VPN service that meets your needs. For this guide, we’ll use ExpressVPN as an example.

Step 2: Install the VPN Client

1. Download the VPN client from your chosen provider’s website.
2. Follow the installation instructions for your operating system (Windows, macOS, Linux, etc.).

Step 3: Configure DNS Settings

After installing the VPN client, follow these steps to configure DNS settings:

For Windows:

1. Open the VPN client and log in.
2. Go to Settings or Preferences.
3. Look for DNS settings. Set the DNS to the VPN’s DNS servers (usually provided by the VPN provider) or use a third-party DNS like Google DNS (8.8.8.8).

Example Code Snippet for Windows:

netsh interface ip set dns "VPN Connection Name" static 8.8.8.8

For macOS:

1. Open the VPN client and log in.
2. Navigate to Settings.
3. Under DNS, choose to use the VPN’s DNS servers or set a custom DNS.

Example Code Snippet for macOS:

networksetup -setdnsservers "VPN Connection Name" 8.8.8.8

Step 4: Verify Your DNS Settings

To ensure your DNS is configured correctly, you can use online tools like DNS Leak Test or IPLeak.

1. Connect to your VPN.
2. Open a web browser and navigate to the DNS leak test site.
3. Run the test. If the displayed DNS servers match those of your VPN, your DNS is set up correctly.
