DNS load balancing is a handy feature for load distribution. This method is used by an increasing number of businesses, both large and small. But how does it work, and what are the benefits? We’ll get to that later in the article.
DNS load balancing – what is the meaning?
To begin, we will define this method. As we already know, DNS is a system that connects a domain name to its IP address. A domain is stored on a single server by default. However, if your site receives a lot of traffic, this can cause it to crash. To prevent this, we use load balancing. To put it another way, this feature redirects DNS queries to multiple web services.

What does a DDoS attack mean?
Distributed Denial of Service, which is for short, called DDoS, is a cyber-attack. It’s performed to disrupt essential targets like a network, system, or server. That is achieved by overwhelming them with lots of traffic, which is coming from many devices. The word “distributed” refers to the many various sources that are used to achieve the attack. When the target is down, the DDoS attack is complete. The outcome is simply not allowing any user to access it.
The DDoS attack can be of several kinds. Techniques can modify, or they could be mixed and accomplish a stronger hit to the target. Overall, any DDoS attack operates by infecting devices. If there are more connected to the Internet, more of them are going to attack the victim. This happens even globally and from any kinds of compromised sources like computers, servers, IoT devices, wearables. The target is not able to handle the traffic. It becomes sluggish and eventually becomes completely drowned.

All types of cyberattacks are threats to take seriously. But DNS attacks directed to hit your DNS (domain name system) are like lethal RIP bullets impacting your system. Your online business can be fully damaged!
DNS cache poisoning.
DNS Cache Poisoning (DNS Spoofing) hits through the DNS resolver servers. They can temporarily save a copy of the DNS records related to domains in their cache memory. Those records get cached the time established in their time-to-live (TTL).

DNS Spoofing explained
You can find DNS Spoofing, also called DNS poisoning. Don’t get confused. It is the same thing. It is a technique applied by hackers which includes imitating a device or a user. That is applied as a cover, with which the disruption of the regular flow of traffic or reaching protected data is not such a difficult task.

Domain Name Security Extensions (DNSSEC) is a great way to add an extra security layer to your domains. It is an advanced DNS feature, which attaches digital signature (DS) records to the DNS information. So, that way, it can establish the authenticity of the source domain name.
The purpose of which it is designed is to protect Internet users from falsified DNS data. An example of such a case can be a misleading or malicious address rather than the actual address you wanted to visit.
Once you enable DNSSEC, the DNS lookups will have to use a digital signature to prove that the origin of the site’s DNS is accurate. It is very helpful for preventing some types of attacks. In case the digital signature does not match, the browsers will not open the site.
