Private DNS server – What is it?

What does a Private DNS server mean?

Although most people utilize public DNS services managed by their preferred ISP, anyone can set up their DNS server. Private DNS is a technique that gives the server owner complete control over the IP addresses and network access that are accessible. They are DNS networks that are independent of the Public DNS.

Furthermore, we refer to Private as DNS over TLS (Transport Layer Security) or DNS over HTTPS (Hypertext Transfer Protocol Secure). While utilizing DoT (DNS over TLS) or DoH (DNS over HTTPS), all DNS queries are encrypted. This makes it far more difficult for shady outside parties to monitor your internet activity.

DNS Propagation Guide: How Long Does It Take for DNS Changes to Propagate?

DNS propagation is a critical concept to understand when making changes to your website, switching hosting providers, or updating domain configurations. Whether you’re modifying DNS records like A, MX, or CNAME, it’s important to know how long these changes take to propagate and why delays occur. We’ll break down the process, explain how long it usually takes, and provide tips on how to minimize wait times.

What Is DNS Propagation?

DNS (Domain Name System) is essentially the phonebook of the internet, translating domain names (like www.example.com) into IP addresses, which are the numerical addresses servers use to find each other.

When you update your DNS records whether changing your website’s IP address, adding an email server, or pointing your domain to a new host—those changes need to propagate throughout the global DNS network.

DNS propagation is the time it takes for the DNS changes to be distributed across all DNS servers worldwide. Until the propagation process is complete, some users might see your website with the old DNS settings, while others see it with the updated ones.

Botnets: The Ultimate Cybercriminal Tool

Botnets represent a potent threat to cybersecurity worldwide. From launching large-scale cyber attacks to facilitating criminal activities like data theft and fraud, they are the clandestine tools of choice for cybercriminals. In this article, we delve into the details, exploring their mechanisms, purposes, and the measures taken to combat them.

What are Botnets?

Botnets represent a network of internet-connected devices infected with malicious software, often referred to as “bots” or “zombies.” These devices, which can include computers, servers, smartphones, and Internet of Things (IoT) devices, are compromised without the users’ knowledge, allowing remote control by a central command-and-control (C&C) server.

Ensuring High Availability with DNS Failover

In today’s digital era, where uninterrupted online presence is not just desired but essential, DNS Failover has emerged as a pivotal solution for businesses aiming to achieve high availability. This comprehensive guide delves into the intricacies of DNS Failover, offering insights into its importance, functionality, and implementation strategies for maintaining continuous online operations.

Understanding DNS Failover

DNS Failover is a process that ensures users can access your website even when your primary server goes down. It works by automatically redirecting traffic to a secondary, operational server. This seamless transition is crucial in a world where even a minute of downtime can lead to significant financial and reputational losses.

The Importance of DNS Monitoring for Website Security

The Domain Name System (DNS) can be likened to the phone book of the internet. It translates human-friendly domain names into IP addresses that computers use to identify each other. When you type in a website address like “www.example.com” into your browser, the DNS system looks up the corresponding IP address, allowing your browser to connect to the website’s server. But, like many foundational internet technologies, DNS is not without its vulnerabilities. This is where DNS monitoring comes into play as a critical component of website security.

What is DNS Monitoring?

DNS monitoring involves regularly observing and analyzing DNS traffic for signs of malicious activity or operational issues. It’s about keeping an eye on DNS resolution processes, understanding regular patterns, and quickly detecting anomalies that could indicate a security threat or performance issue.

Detailed guide of how DNSSEC works

DNSSEC adds the security to DNS that it desperately needs. It is a chain of trust that guarantees that the data (DNS records) were not modified on the way and that they come from the right source.

​What is DNSSEC?

DNSSEC is a set of security measures that protect DNS data by providing cryptographic authentication, authenticated denial of existence, and data integrity.

DNSSEC basically proves that the data came from the right source, stops data that can’t prove the right source, and data that was modified on the way.

Understanding DNS Spoofing: A Guide for Non-Techies

DNS spoofing is a malicious cyber attack that can redirect users from a legitimate website to a malicious one. It is becoming increasingly common and can be used to steal sensitive information, launch denial of service attacks, or intercept and modify data. As a result, organizations must implement a multi-faceted approach that includes technical and administrative security measures to protect their networks. In this article, we will explain what DNS spoofing is, how it is performed, and how to prevent it.

DNS Spoofing briefly explained

DNS Spoofing, also known as DNS Cache Poisoning, is a type of cyber attack where an attacker exploits a vulnerability in the Domain Name System (DNS) to redirect internet users from legitimate websites to malicious ones. By manipulating the DNS records, an attacker can redirect users to a malicious website that looks legitimate and can dupe unsuspecting victims into providing sensitive information, such as bank details, or downloading malicious software. The attacker can also use DNS spoofing to launch a Denial of Service (DoS) attack, where the attacker floods the target website with fake requests to overload the server and make it unavailable to legitimate users. DNS Cache Poisoning attacks are becoming increasingly common, making it vital for organizations to take steps to protect their networks from this type of attack.

The Top 3 Worst DDoS Attacks in History

Don’t let a DDoS attack bring your business to a halt! You can guard against devastating attacks and maintain your network performance with the proper protections. Learn how to defend against DDoS attacks and what are the worst ones you need to know about!

What is the objective of DDoS attacks?

A Distributed Denial of Service (DDoS) attack is an attack on a digital system or network to make it inaccessible or severely slow down its performance. The purpose of a DDoS attack is to cause disruption and damage to the targeted system or network. The attacker will typically send large amounts of malicious traffic to the system or network to overwhelm it, thus denying other users access to its resources or services. In some cases, the attack may even be targeted at specific systems or users. The ultimate goal of a DDoS attack is to render the system or network useless to its users and owners.

Round Robin Load balancing explained in detail

Are you looking for a way to make your business more efficient and flexible? Then, Round Robin Load balancing is the perfect solution! This technique helps to distribute requests evenly across a cluster of servers or other resources, ensuring that each server is used roughly the same number of times. 

Meaning of Round Robin Load balancing

Round Robin is a Load balancing technique of evenly distributing requests across a cluster of servers or other resources. It works by making a list of available resources. Then it uses an algorithm to assign one server at a time to each request, rotating through the list of available resources until all have been used before starting again at the top, hence the “Round Robin” name. This ensures that each server is used roughly the same number of times so that all resources are utilized as evenly as possible. This is beneficial as it allows for greater flexibility and scalability as more tasks can be distributed, and any single resource is less likely to become overloaded. It also improves efficiency by providing continuity and ensuring no single resource handles more than its share.
