Round-trip time, or RTT, is one of the key metrics for measuring speed and efficiency. If you’re new to networking, understanding it can help you grasp how data travels across the internet and how quickly it does so. With this article we aim to explain the crucial metric in simple terms, why it’s important, and how it impacts your online experience. So, without any further ado, let’s begin!

What is RTT (Round-Trip Time)?

RTT (Round-Trip Time) measures the time it takes for a data packet to travel from your device (like a computer or smartphone) to a server on the internet and back again to your device. In simpler terms, it’s the time taken for a message to go to the destination and for the response to come back.

Imagine sending a letter to a friend who lives far away. RTT is the time it takes for the letter to reach your friend and for your friend to send a reply back to you. In networking, however, this entire process happens in milliseconds.

In the world of networking, the ability to remotely access and manage devices is a crucial capability for administrators. Two protocols stand out in the realm of remote communication: Telnet and SSH (Secure Shell). While both serve the primary function of remote access, their approach to security and data handling differs significantly. So, let’s explain a little bit more about them!

What is Telnet?

Telnet, an abbreviation for “Teletype Network,” is one of the oldest internet protocols developed in 1969. It was designed to allow users to communicate with a remote computer over a network. Telnet operates on a client-server model where the client software connects to the server software running on the remote machine. The protocol is known for its simplicity and effectiveness in allowing users to manage servers and other devices remotely.

Billions of users navigate the Internet daily, while DNS outage stand as potential disruptor, capable of causing chaos and confusion. These outages, though often temporary, can have significant repercussions on internet services, affecting everything from website accessibility to email delivery. Understanding what they are, why they occur, and their potential dangers is crucial for both internet users and service providers. So, without any further ado, let’s begin!

What is a DNS Outage?

At its core, the Domain Name System is like the Internet’s phonebook, translating user-friendly domain names (like example.com) into machine-readable IP addresses (such as 192.0.2.1). DNS servers, distributed across the globe, facilitate this translation process, ensuring that when you type a website’s name into your browser, you’re directed to the correct server hosting that website.

A DNS outage occurs when the DNS servers fail and become unable to do their translation duties. It can happen due to various reasons, including:

In the digital realm, Time-to-Live (TTL) is a crucial concept that impacts various aspects of technology, from networking and web caching to DNS resolution and database management. Understanding TTL and its significance can enhance system efficiency, improve user experience, and ensure the security and reliability of digital services. This blog post delves into the importance of TTL, explaining why being aware of it is essential for professionals and enthusiasts alike in the tech world.

What is TTL?

Time-to-Live (TTL) refers to a mechanism that limits the lifespan or validity of data in a computer or network. In networking, TTL is a value in an Internet Protocol (IP) packet that tells a network router whether the packet has been in the network too long and should be discarded. In caching systems, TTL dictates how long a piece of data should be stored before it’s considered stale and needs to be updated or removed.

In today’s digital landscape, where businesses heavily rely on the internet for communication, transactions, and operations, the security of online activities has become paramount. While organizations implement various cybersecurity measures to safeguard their sensitive data, one lesser-known yet highly potent threat remains – DNS spoofing. This article sheds light on the potentially catastrophic consequences of DNS spoofing for businesses and highlights the urgency of addressing this hidden peril.

What is DNS spoofing?

DNS, or Domain Name System, serves as the internet’s phonebook, translating human-readable domain names into IP addresses that computers use to locate and connect with each other. DNS spoofing involves manipulating this translation process, leading users to fraudulent or malicious websites that closely resemble legitimate ones. Attackers accomplish this by corrupting the DNS cache, rerouting traffic to malicious servers, and subsequently gaining unauthorized access to sensitive information.

Additional security is always welcome and never a waste! We live in a very dangerous cyber world. When you check the number of threats on the Internet and the statistics they produce, enhancing your security makes total sense. So what does it mean to get additional security with a Secondary DNS service? Here you have the answer!

What is a Secondary DNS service?

Secondary DNS is a type of DNS service that allows you to add another name server or a network of multiple name servers to save copies of the zone file that include the DNS records of your domain. These copies can’t be modified. You can set up this extra name server (or name servers) to copy, automatically, the DNS records (A, SOA, NS, MX, PTR, DS, TXT, etc.) from the Primary DNS.

An outstanding Secondary DNS service that is worth your attention!

Running an online business will get you close to a wide number of technology concepts and solutions like load balancing. The best is to get familiar with them, but don’t get overwhelmed! The objective is to understand if you need them now or if they will be a solution for you in the future.

Load balancing – Definition

Load balancing is a method to distribute traffic loads among multiple servers. You may have observed a server of your network stressed by the excessive workload and maybe others being barely demanded. Load balancing’s objective is to distribute the work to make your processes more efficient and your traffic more agile. There are different load balancers (technologies) on the menu. You can study them and choose the best option for your business needs.

How does Load balancing work?

Our article today aims to break down the importance of DDoS Protected DNS service. In addition, we will explain what exactly is a DDoS attack. So, let’s not waste any more time and explore it!

Purpose of DDoS Protected DNS service

DDoS protected DNS is a robust network with servers strategically located around the world. Servers do an excellent job of balancing traffic load. To be prepared in the event of an attack. When traffic spikes are observed, network servers share the burden. Even if an attacker manages to bring down a server, more will continue to work for your company, causing no downtime.

Enhance your protection with DDoS protected DNS

DNS attack types are getting more and more every year. Just as the Internet expands every day, unfortunately, online crime grows too. Motivations can be different. Extortion is on the top rank, but also boredom, people trying to prove their computing skills, the so-called hacktivism, or to take down a competitor.

In any case, different DNS attack types take advantage of the multiple Domain Name System (DNS) vulnerabilities. They have different ways to operate but all of them are dangerous for your business. Let’s get familiar with the most popular DNS attack types.
