Quad9 DNS: Internet Security and Privacy in a Few Easy Steps

When you type the name of a website into your browser, the request goes to a DNS (Domain Name System) server, which returns the numerical IP address of the site in question so the browser can find it.

Most people use the default DNS server provided by their ISP, and while it will be perfectly adequate, it may not be the fastest or most secure.

Quad9 is a new security solution from IBM, PCH and the Global Cyber Alliance that promises to improve your system’s security, privacy, and performance by routing requests through its own DNS servers, which have been designed to prevent you from accessing unsafe sites.

Your requests are handled by the nearest data centers, which should result in a speedy response. Quad9 doesn’t record or store your browsing history.

How Quad9 works

Quad9 routes your DNS queries through a secure network of servers around the globe. The system uses threat intelligence from more than a dozen of the industry’s leading cybersecurity companies to give a real-time perspective on what websites are safe and what sites are known to include malware or other threats.

If the system detects that the site you want to reach is known to be infected, you’ll automatically be blocked from entry – keeping your data and computer safe.

How to Setup Quad9 On Windows PC

Open the Run menu and enter the command “ncpa.cpl

and right-click on your Network card and select “Properties” and select the Internet protocol version IPv4 and click on the “Properties” option.

In the Properties window that opens, ‘Obtain DNS server address automatically’ should be selected (unless you’ve changed this previously for some reason). To enter the new Quad9 details and secure your DNS, select ‘Use the following DNS server addresses’.

In the ‘Preferred DNS server’ box, type the address for Quad9. It’s ridiculously easy to remember: (which is why it’s called Quad9). You don’t need to enter
anything into the ‘Alternative DNS server’ box. Click OK and close the rest of the boxes. Everything is now set up for you to use.

You can also set up Quad9 on your router, so all your devices connect to the internet via the more secure DNS.

The process will vary depending on your router, but Setup Router (setuprouter.com) should be able to help. Click the initial letter of your router and find the exact model.

Log into your router using the instructions on the website. You’ll need to enter the IP address for the router into your browser, then enter your password (and maybe other
details). Find the DNS settings option and enter the Quad9 details ( Not all routers allow you to change the DNS setting.

Once your new DNS provider is set up, just browse the web as you would normally – you shouldn’t notice anything different (although pages might load a little quicker). If you try to access a ‘bad’ page, however, Quad9 will act as if the domain simply doesn’t exist and your browser will return an error message.

Quad9 also offers a DNS server that doesn’t protect you from malicious sites or provide any other security – it simply behaves like a regular DNS server.

To use it, open the Internet Protocol Version 4 (TCP/IPv4) Properties window and enter as the primary DNS. Only ever use one of the addresses – either or
