Unbreakable VPN Connection with Custom DNS by Combining Starlink, Wi-Fi, 4G, 5G, and DSL with Speedify
Every time you type a web address, your device asks a lookup service – DNS – to turn that name into the number of the right computer. A custom DNS setting lets you choose who does those lookups.
Some VPN services let those lookups slip outside the encryption, where your internet provider can still see every site you visit. Speedify keeps them inside, and carries your traffic over Wi-Fi, 4G/5G cellular data, wired Ethernet, Starlink and other internet connections at once.
The rest of this article lists the fastest DNS services, shows how to change the setting on a computer or phone, and explains what Speedify adds – private lookups plus faster uploads and downloads.
Should you have a backup 4G, 5G, Starlink, or cable internet connection?
Yes — every internet connection goes down, including Starlink, which drops for ~34 minutes a day on average. A backup connection from a different provider means one outage never takes you fully offline. The most common options are a 4G/5G cellular hotspot, a cable or DSL line, or a second satellite dish.

Works anywhere. Just a SIM or hotspot — no installation needed.

The Domain Name System (DNS) is the phone book of the Internet. This is the service that turns URLs like “speedify.com” or “google.com” into IP addresses. These addresses are then used to connect you to the right server.
We will look at DNS servers from 2 main perspectives: speed and security.
VPN Custom DNS and How It Can Improve Internet Speed
Whenever you try to connect to a website or service, your device queries the DNS server to find out the IP address. If that DNS server is located close to where you are, things will load quickly, whether you’re browsing, live streaming or playing online games with low latency.
If the DNS server is far away, there will be lag added to your connection. However, in some cases it’s recommended to use a DNS server from a certain country to avoid content restrictions. This is because some content services check the DNS server along with the IP address of the client.
The conclusion? Being able to use a custom DNS server can speed up your connection.
How VPN Custom DNS Help with Online Privacy
VPNs are the best solution to protect your online privacy, as they create a tunnel between your computer and the Internet. Unfortunately, not all VPN services make your online activity fully anonymous. Here’s how to find out if you’re exposed or not by DNS leaks. It’s crucial to get DNS leak protection from your VPN service.
DNS servers are used to resolve Internet addresses. There are multiple DNS servers you can use, though usually your ISP decides. This raises some privacy questions:
- All requests go through the ISP default DNS
- This means that, in theory, ISPs can create an online profile for you
- Even if you’re using a VPN to encrypt your traffic, it may leak DNS requests (see above).
The solution to stay 100% anonymous online: use VPN custom DNS. Doing so will keep DNS requests within the VPN tunnel.
What’s the Fastest DNS Server You Should Use With Your VPN?
Speedify bonding VPN encrypts and protects your DNS traffic. No one can spy on your Internet connection to see what sites and services you’re using. This is very useful for avoiding ISP throttling.
Starting with version 7.4, Speedify includes a VPN custom DNS feature. This lets you pick which DNS service to use as your “phone book”. Different DNS services have different features, which can be helpful. Out of the box, Speedify supports a number of popular DNS services, all with their own strengths:
- CloudFlare Quad One – the new privacy-first DNS service
- Google’s Quad Eight – fast DNS from Google
- OpenDNS Home – DNS service with built-in phishing protection
- AdGuard DNS – a DNS service with a built-in ad blocker. Websites that are known to serve ads can’t be looked up, leading to fewer ads in web pages.
Need a different DNS server? You can also select “Custom” and enter a DNS server of your choice by IP address.
