​DDoS-protected DNS service: Why do you need it?

If you are checking what DDoS-protected DNS service is, you probably already suffered from a DDoS attack. Now, they are more common than ever and damage online businesses. They might stop your server when you needed it the most and cause severe losses. It is clear that you need a way to stay safe and keep your online business running. You need DDoS protected DNS service! 

​What is DDoS protected DNS service?

DDoS protection or DDoS mitigation service refers to an additional DNS service that combines different tools and techniques to check traffic and stop DDoS attacks. The DDoS attacks are strong waves of traffic organized by cybercriminals that try to unstable your servers and make them incapable of responding to normal clients’ requests.

What does IPv4 mean?

Something as massive as the Internet needs a way of control, some not to be driven by chaos. Just think about the number of devices that demand connection every second worldwide. In origin, developers perhaps didn’t imagine the Internet would grow as fast and big as it is going. But they definitely thought big, so they calculated ways to keep the order. So different rules and protocols were created, like the Internet protocol (IP).

To fully understand the meaning of IPv4, we have to review some concepts. Let’s get started!

IP definition

The IP or the Internet protocol is a group of rules for online communications. It rules the format of data packets, the most convenient structure for data to be transported across networks. It’s also in charge of routing and addressing data packets delivered to their destination using the IP addresses. 

IP address definition

An IP address allows the Internet to identify devices participating in each communication. It’s an identifier of most of the components (servers, routers, domains, computers, smartphones, IoT devices, etc.) included within a network.

The main point is that the Internet must know who is talking, who requests information, and whom to answer. This is the reason for assigning a unique IP address to every device that requests a connection. 

Through the use of IP addresses, you can locate machines in the network and make them accessible for communicating and exchanging information. 

What does IPv4 mean?

Now we can put all the pieces together. IPv4 means Internet Protocol version 4. It’s the original version of the IP. It was a consequence of the TCP/IP improvement. SATNET, the early satellite network that shaped an initial segment of the Internet, used it for the first time in 1982. One year later, it was officially adopted by ARPANET, the Internet’s ancestor. 

The IPv4 structure involves 4 numbers between 0 and 254 divided by dots. It’s a four-byte (32-bit address space) long address. It was meant to cover the demand for connection of 4.3 billion computers. IPv4 example:

It’s described as a connection-less protocol, and that is because communication (exchange of messages) can start without prior arrangement between two endpoints on a network. In other words, a device can send information to a recipient without verifying if it’s available for establishing the communication or if it’s able to receive the information.

IPv4 duties are defining the format, communicating, addressing, and routing. That’s it! It’s not responsible for several tasks like protecting data integrity, securing the order, assuring the correct delivery, or avoiding duplicate delivery. No doubt these are critical tasks but, to accomplish them, it must be combined or complemented with a different protocol, for instance, the transmission control protocol or TCP.

Due to these features, IPv4 became a crucial tool for networks and the transmission of data they constantly do. Its use ensures data packets format will be checked. In case they are too big, they will be chopped into smaller pieces for faster and easier transmission. Communication will go on, and data packets will be addressed and routed to jump from an Internet module to the next and so on until they arrive at their destination. 


IPv4 has evolved through time and kept a great reputation. But even it’s still highly demanded, there is a shortage of this resource since a long time ago. Devices demanding connection are more every day, and IPv4 is already not enough. Sooner than later, we will have to migrate to the newest protocol version.

Fully Qualified Domain Name (FQDN) explained.

What is FQDN?

FQDN is the short acronym for Fully Qualified Domain Name. With it, you are able to see precisely the most full name of a specific domain name. And that refers not only to websites but also to servers. The Domain Name System (DNS) is created with a hierarchy order. It starts from the top, which is the root, then TLD, after that the domain, and the last is the specific hostname.

DNS outage explained

You have to pay urgently to some providers, and after several tries, your bank website is unreachable. You have been chasing a promotion to renew some equipment. The promotion appears, but when you try to load the website, you receive only error messages. 

As clients, we all have experienced this more than once. We hate the website, and we don’t feel like giving it another chance. It will take a long time to forget the bad experience.

On the other side, as online business owners, we don’t want to suffer this because we understand its cost for our pockets and reputation!

​What is a DNS zone file?

​Some DNS background.

The DNS is a system of managing domains and IP addresses. It has a specific tree-like structure built with hierarchy. For administrative purposes and to make the whole system more manageable and decentralized, it uses delegated partitions called DNS zone. The DNS zone is a part of the Domain namespace that has its autonomy of management.

Introduction to Anycast DNS

Anycast DNS explained.

Through Anycast DNS, several servers that are located in different geographical points can provide the same IP address. The DNS data for your domain name is duplicated on more than one server. You are able to choose a specific number of servers, depending on your needs. That way, your overall presence is going to be better.

When you are using Anycast, the most nearby server is going to answer the request of the user. In case one of your servers is offline due to maintenance or down for some reason, your website is still going to be reachable. The request will move to the second closest and available DNS server to resolve. As a result, the user’s request is going to be answered faster. Also, the overall experience is going to be improved in terms of loading time, waiting for a response, and so on.

What is cPanel?

cPanel is a software specially designed to supply a graphical interface for managing easily the daily tasks involved with hosting a website. 

Additionally, it provides you text interface (command line), automation tools to make administrative tasks easier, and API (application programming interface) based access. This last means a software interface that connects computers and different software. It helps you to manage the different programs you need to install for running your website.
