DNSSEC Explained: The Basics You Need to Know

Understanding DNSSEC is crucial for website owners who want to be safe and protected from malicious attacks. In this blog post, we’ll cover the basics of DNSSEC, including what it is, why it’s important, and how it works. So, without any further ado, let’s begin!

What is DNSSEC?

DNSSEC (Domain Name System Security Extensions) is a protocol that adds a layer of security to the Domain Name System (DNS). The DNS is responsible for translating domain names (like into IP addresses that machines can understand. It was created to handle a vulnerability in the DNS that allows malicious actors to intercept DNS queries and redirect regular users to fake websites.

Why is DNSSEC important?

Without DNSSEC, it’s easy for hackers to spoof DNS responses and redirect users to malicious websites. This is known as a DNS cache poisoning attack, and it is commonly initiated to steal sensitive information like login credentials or credit card numbers. It provides a way for website owners to protect their users by ensuring that the DNS responses they receive are authentic and haven’t been tampered with.

How does it work?

DNSSEC uses a system of cryptographic keys to sign DNS records. When a user requests a DNS record, the DNS server returns a signed response that includes a digital signature. The user’s computer can then verify the signature using the public key of the DNS server. If the signature is valid, the user can be confident that the response is authentic.

Implementing DNSSEC

Implementing DNSSEC is a straightforward process, but it does require some technical knowledge. Here are the basic steps involved:

  1. Generate keys: The first step is to generate a pair of cryptographic keys – a private key and a public key. The private key is kept secret and used to sign DNS records, while the public key is published in the DNS for users to verify signatures.
  2. Publish the key: The DNSSEC public key is published in the DNS as a DNSKEY record. This record is signed with the private key to ensure that it can’t be tampered with.
  3. Sign DNS records: Once the DNSSEC key is in place, DNS records can be signed using the private key. This ensures that any DNS responses sent to users can be verified as authentic.
  4. Test: Finally, it’s important to test DNSSEC to ensure that it’s working correctly. This involves checking that DNS responses are being signed and that users can verify signatures using the public key.


DNSSEC is an essential protocol for website owners who want to protect their users from malicious attacks. By adding a layer of protection, they are able to strengthen the security of their Domain Name System (DNS) infrastructure. 

Get familiar with DNS services

If you are looking for DNS services, you may have heard that they may improve domain resolution and enhance the functionality of your website. But how do they manage it? What is a DNS service? No worries. You will now discover.

Understanding of DNS

The Internet phonebook known as Domain Name System (DNS) links domain names to their IP addresses (domain resolution). So, all you need to do is locate the domain’s IP address for your device to load the website’s content.

DNS services – What does this mean?

By providing more servers closer to the customers who can respond more quickly, cloud-based DNS services, both Free DNS and Premium DNS (paid), can help increase the speed of domain resolution (the matching of a domain to its IP address). As a result, you’ll be able to respond to user queries more quickly and with less work on your DNS infrastructure if you have more servers spread across the globe.

Free DNS services: Meaning & Application

Great, we now understand the general characteristics of DNS services. Now let’s go into greater detail about the Free version and its contents.

It has a small number of features in the broadest sense. For instance, this plan frequently has Unicast DNS servers and a cap on DNS zones, records, and requests per month. Additionally, this plan often includes web redirection and Dynamic DNS.

Who is it appropriate for? For websites with little traffic and few queries, this strategy works best. However, a Premium DNS service is your best option if your website receives a lot of traffic. In the section after this one, let’s look at it.

Premium DNS vs Free DNS

And what does Premium DNS mean?

When talking about the Premium DNS service, you need to pay either monthly or per resource used (number of queries, number of servers, etc.). The best option is to select a monthly membership because you can better manage your spending this way.

Your domain name’s availability and speed will both significantly increase with the premium service. In addition, when you pay, you get a high-quality service from professionals who will make every effort to maintain their DNS network operational nearly 100% of the time as is practical.

So, we can say that with Premium DNS, it’s simple to:

  • Reduce the number of error codes and dropped queries.
  • Boost the loading and resolution times of the website. (improve the SEO)
  • Protect confidential data from hacker activity.
  • Protect your website from hackers attempting to reroute it to steal essential consumer data. 

In addition, Premium DNS provides the following features:


It’s critical for your business to have a reliable DNS service. You should consider several factors, such as the essential requirements of your website and the hosting environment you envision while selecting the greatest DNS hosting companies for you. Additionally, you should have a broad notion of the features, speed, and dependability you desire in your hosting service. But kindly avoid waiting till the worst occurs. Instead, consider establishing good DNS service to increase redundancy and reduce or stop DDoS attacks. Best of luck!
