What is 9.9.9.9? It is the primary IP address of Quad9, a public recursive DNS resolver service. Before moving on to what this does for the security and privacy of internet users, it is important to understand the origin of Quad9.

Quad9 was founded by an amalgamation of organizations, including the Global Cyber Alliance ( GCA ), Packet Clearing House ( PCH ), and IBM. It is also important to note that a non-profit organization operates Quad 9.9 DNS. 

So what is the primary objective of this DNS resolver? We understand that the internet is not a safe place anymore because there can be a lot of malware and maliciousness around.

9.9.9.9 – What Quad9 does for your internet privacy and security

Now let’s move on to what Quad9 can do for you while browsing or using the internet.

Optimal security and malware blocking

It is important to understand that Quad9 is very advanced because it incorporates a threat intelligence feed. This feed helps Quad9 get data about malicious or harmful websites from different sources, including cyber security companies or even law enforcement agencies, so that it can block them. 

For instance, if you are using Quad9, you can be saved from malware infections, online threats, or phishing. Even if you want to access malicious websites, you won’t be able to because it will block these threats at the DNS level, and that is a great defense against online mafia activities.

Reliable and protective 

Quad9 is not operated by something individual. It is extremely reliable because of the wonderful Global networks of DNS servers worldwide. Because of these Global networks, you can be sure about reduced latency, reliable service availability, and infrastructure improvement. 

Also, it does not track or log any user activity related to personally identifiable information (PII). This helps the user to stay secure and browse the Internet without any privacy concerns.

Botnet protection and DNSSEC support

Quad9 is extremely reliable for Botnet Protection. But what exactly are Botnets? These are some devices that the malicious actors genius control. 

These devices are so potent that they can launch large-scale attacks called distributed denial ( DDos ) of service, which can compromise users’ security. But because of the reliability of Quad9, users can stay safe because it blocks and identifies them.

At the same time, Quad9 wonderfully supports DNSSEC further to enhance the integrity and authenticity of DNS responses.

It is easy and fancy when you want to set up Quad9 on your device. You can easily configure your network settings or device to use Quad9 DNS servers like 9.9.9.9 so it can act as a DNS resolver. Installing this software on your preferred application or device is also possible to further enhance the configuration process.

Role of DNS resolvers in enhancing Internet security with advanced tech

Before you get to understand the DNS resolvers more intimately, it is important to understand DNS ( Domain Name System )

So basically, the DNS is an important internet component that translates human-readable domain names into related IP addresses. 

We all know that on the Internet, computers and devices communicate or interact with each other with the help of IP addresses. IP addresses are always numerical identifiers. 

DNS is a distributed database that manages different things between domain names and IP addresses. For instance, when you want to access a certain website on the Internet, the DNS translates that into a particular IP address so you can view it. 

DNS also allows you to: 

• access certain websites and perform various online activities by recognizing the domain names instead of memorizing the difficult IP addresses. 
• Had DNS not been there, you would have had to learn every IP address before accessing the website, which would have been gruesome. 

Where does a DNS resolver help?

DNS does not operate individually; it takes the help of different components that include authority names servers, domain registrars, and recursive resolvers. When we talk about a resolver like Quad9, it helps the DNS find the relative IP address. 

For example, when a user searches for a particular website and enters the domain name. At that point, a resolver helps the DNS to find the corresponding IP address.
