What Is a DNS Leak and Why Does It Happen on Fios?

When you type a website address into your browser, a DNS (Domain Name System) server acts like a phonebook, translating the name (like cybervpnhub.com) into an IP address that your computer can understand. Normally, your VPN should route all these requests through its own private, secure DNS servers. A DNS leak occurs when these requests accidentally get sent to your Internet Service Provider's servers instead—in this case, Verizon's.

Verizon Fios uses its own DNS servers by default. The combination of Fios's router settings and certain VPN configurations can sometimes cause your device to bypass the VPN's secure tunnel for DNS lookups. This means Verizon can see every website you visit, even if you're connected to a VPN. Common causes include:

• IPv6 Leaks: Many older VPNs don't fully support IPv6. Since Fios supports IPv6, your device might use it for DNS requests, bypassing your IPv4-only VPN.
• Router Configuration: Fios routers can be configured to use Verizon's DNS forcefully, overriding your device's settings.
• VPN Software Flaws: Not all VPNs have robust leak protection built-in, and a dropped connection can instantly expose your DNS.

How to Test for a DNS Leak Right Now

The good news is that checking for a DNS leak is simple and free. You should perform this test immediately after connecting to your VPN to ensure it's working correctly.

1. Connect to your chosen VPN server. For the most accurate test, choose a server in a different country.
2. Visit a DNS leak test website, such as DNSLeakTest.com.
3. Run the “Extended Test.” This will take a minute or two to complete.
4. Analyze the results. The test will show you a list of the DNS servers that responded.

If you see servers listed that belong to your VPN provider, you are protected. If you see servers associated with Verizon or your location, you have a DNS leak. If a leak is detected, don't panic. The following sections will guide you through fixing it.

Best VPNs with Built-in DNS Leak Protection

The easiest way to prevent DNS leaks on Verizon Fios is to use a VPN that has DNS leak protection enabled by default. These providers operate their own private, encrypted DNS servers and have measures in place to block any accidental requests from going to Verizon.

Based on our independent testing, these providers consistently maintain a watertight connection on Fios networks:

• NordVPN: Its Threat Protection feature includes robust DNS leak blocking and automatically uses Nord's own private DNS servers.
• Surfshark: Comes with a built-in firewall (CleanWeb) that prevents any data from leaving your device outside the VPN tunnel.
• ExpressVPN: Runs its own private, encrypted DNS on every server, making leaks virtually impossible.

Step-by-Step Guide to Fixing and Preventing DNS Leaks

If your test revealed a leak, or you want to proactively secure your setup, follow these steps.

1. Enable Your VPN's Built-in Leak Protection

First, dig into your VPN's settings. Look for options labeled “DNS Leak Protection,” “IPv6 Leak Protection,” or a “Kill Switch.” Ensure every one of these features is turned on. A kill switch is particularly crucial as it will cut your internet connection if the VPN drops, preventing any data from being exposed.

2. Manually Configure Your DNS Settings

For an extra layer of security, you can manually configure your device to use a trusted third-party DNS service like Cloudflare (1.1.1.1) or Google DNS (8.8.8.8). However, your VPN should handle this automatically. If you manually set these, your VPN should still override them. This is more of a backup measure.

3. Disable IPv6 on Your Device

Since Verizon Fios supports IPv6 and many VPNs have had historical issues with it, disabling IPv6 on your computer or device is a highly effective fix. You can find guides for disabling IPv6 on Windows, Mac, and other devices on our site.

4. Check Your Fios Router Settings

Log into your Verizon Fios router administration panel (usually by typing 192.168.1.1 into your browser). Navigate to the internet settings and see if DNS settings are being forced. You may not be able to change them, but it's worth checking. For the most robust solution, consider using a VPN that can be installed directly on your router, encrypting traffic for every device in your home.
