Detailed explanation of Private DNS server

While most people rely on public DNS server provided by ISPs or companies like Google and Cloudflare, there exists another category known as private DNS servers, which offer distinct advantages for organizations and individuals alike. So, without any further ado let’s explain more about it!

What is a Private DNS Server?

A private DNS server is a DNS server that is not publicly accessible and is typically used within a closed network environment. Unlike public DNS servers that are accessible to anyone on the internet, private DNS servers are restricted to a specific organization, enterprise, or even individual users.

DNS Hijacking: Understanding the Threat and Staying One Step Ahead

In the ever-evolving landscape of cybersecurity threats, DNS hijacking has emerged as a particularly insidious method used by cybercriminals. It’s a technique that can redirect users from legitimate websites to fraudulent ones without their knowledge. This post aims to shed light on what DNS hijacking is, how it works, its implications, and most importantly, how you can protect yourself from such attacks.

What is DNS Hijacking?

DNS (Domain Name System) is often likened to a phonebook of the internet. It translates domain names that humans can read (like into the IP addresses that computers use. DNS hijacking occurs when this process is manipulated by attackers, leading your requests to a different destination than intended.

UDP: Definition

What is the UDP goal?

User Datagram Protocol generally refer to as UDP. It is an essential part of the family of Internet protocols. With little latency and loss tolerance, it enables us to connect multiple Internet services.

The delivery of data prior to the recipient’s consent speeds up communication thanks to the User Datagram Protocol. Therefore, User Datagram Protocol is the preferred method for time-sensitive communications like DNS lookups, Voice over IP (VoIP), video, or audio transfers.

Anycast DNS: Definition & Benefits

You still don’t know what Anycast DNS is? If yes, don’t worry. In this article, we will explain its definition and how it functions. Then, finally, we will see its fundamental benefits. Let’s now explore this exciting topic.

What is Anycast DNS definition?

Anycast DNS is a DNS routing technique that uses several name servers to provide a single IP address. Anycast DNS is designed to distribute nameservers around various regions on the planet and offer users nearby servers. The nameserver with the same IP address nearest to the user when they request a domain will respond to their DNS query. The domain resolution process moves faster thanks to the query’s shorter route, which minimizes latency.
