What’s the difference between DNS leak and IP leak? This 2025 US-focused guide explains how both leak your identity, how to test them, and fix them fast.
What Are DNS & IP Leaks?
Privacy is no longer optional in the USA. Whether you’re streaming, banking, or just browsing, your online identity is at risk.
You may be using a VPN, thinking you’re safe—but suddenly, your real IP address or DNS queries are exposed. That’s what we call an IP leak or a DNS leak.
But what’s the difference between DNS leak and IP leak?
And more importantly—how do you fix both?
This guide explains the differences, how they happen, and gives US-specific solutions you can apply today on Windows, Android, Mac, and even routers.
Let’s dive in 👇
What is an IP Leak?
An IP leak occurs when your real IP address (provided by your US internet provider like Spectrum, AT&T, etc.) becomes visible online even when your VPN is active.
This can expose:
- 🧭 Your city & ZIP code
- 👁️ Your ISP (Internet Service Provider)
- 📍 Your exact location
- 👮 Your browsing activities to authorities or advertisers
Real US Example:
You’re watching Hulu using a VPN server set to the UK.
But Hulu detects your real US IP because your browser or app bypassed the VPN.
Now your location is leaked—and the VPN is useless.
What is a DNS Leak?
A DNS leak means your domain name queries (the websites you visit) are being sent to your ISP’s DNS servers, not your VPN’s encrypted DNS.
Even though your IP may be hidden, your DNS tells a story:
- You visited
facebook.com,youtube.com,digimad.online, etc. - These logs can be tracked, stored, or sold by US ISPs.
Real US Example:
You’re using a VPN, but Chrome is still using your ISP’s DNS (like Comcast or Verizon).
This means every website you visit is visible to them—even with a VPN.
🧱 DNS Leak vs IP Leak: What’s the Difference?
| Feature | IP Leak | DNS Leak |
|---|---|---|
| What it reveals | Your real IP address | The websites you visit |
| Main risk | Reveals your location & identity | Exposes your browsing habits |
| How it happens | VPN fails to mask IP | DNS requests go to ISP |
| Detection | IP leak test tools | DNS leak test tools |
| Impact | Major privacy risk | Medium to high tracking risk |
| Fix | Kill switch, firewall, trusted VPN | Encrypted DNS, disable ISP DNS |
Why These Leaks Are Dangerous in the USA
In the United States, ISPs are legally allowed to:
- Collect your DNS data
- Sell it to advertisers
- Share with government agencies
A DNS or IP leak:
- Destroys your VPN’s purpose
- Allows targeted ads
- Gets you blocked from streaming services
- May compromise your identity
🔬 How to Check for DNS Leak or IP Leak (US Users)
1. Use Online Tools
Visit these free tools:
2. What You Should See
- If using a VPN, the IP address shown should be not from your city or ISP
- DNS servers should show your VPN provider, not your ISP (like AT&T, Xfinity, etc.)
How to Fix an IP Leak (USA Guide – 2025)
1. Use a VPN With Kill Switch
This feature disconnects internet access if the VPN fails.
Best US VPNs with Kill Switch:
- NordVPN
- ExpressVPN
- ProtonVPN
2. Disable WebRTC (Browser Fix)
WebRTC leaks can expose IP.
Use browser extensions like:
- “WebRTC Network Limiter” (Chrome)
- “uBlock Origin” (all browsers)
3. Avoid Split Tunneling
Split tunneling can cause some apps to bypass VPN.
Turn it OFF in VPN settings unless necessary.
🧰 How to Fix DNS Leak (USA Guide – 2025)
1. Use a VPN with Private DNS
Ensure your VPN uses its own DNS servers and supports DNS over HTTPS (DoH).
2. Disable IPv6
Many DNS leaks are caused by IPv6.
Disable it on your router or device:
- Windows: Network Settings → Adapter → IPv6 → Uncheck
- Android: Use VPN that blocks IPv6 (like ProtonVPN)
3. Change DNS to Encrypted DNS
Manually set your DNS to:
- Cloudflare:
1.1.1.1 - Google DNS:
8.8.8.8 - Quad9:
9.9.9.9
Better: Use Cloudflare’s WARP for encrypted DNS without VPN.
📱 US Device-Specific DNS/IP Leak Fixes
Windows:
- Turn on VPN Kill Switch
- Disable IPv6
- Check DNS settings manually
- Use browser with WebRTC disabled
Android:
- Use VPN with IPv6 + DNS protection (ProtonVPN, Mullvad)
- Don’t use “Split Tunneling”
- Turn on “Always-on VPN” + “Block Connections Without VPN”
macOS:
- System Preferences → Network → Advanced → Uncheck IPv6
- Use DNSCrypt or Cloudflare DNS app
- Safari: Disable WebRTC with Terminal tweak
Routers:
- Use VPN at router level (Asus, Netgear with OpenVPN/WireGuard)
- Disable ISP DNS
- Use 1.1.1.1 for router DNS
