IPsec, short for Internet Protocol Security, helps your data stay safe when it’s sent over the Internet. It’s a tool that protects your information while it travels from one device to another. Let’s break it down in the simplest way possible.

What is IPsec?

IPsec (Internet Protocol Security) is a way to make sure data stays private, unchanged, and from a trusted source when it moves across a network. Think of it like sealing your messages in a tamper-proof, secret envelope that only the right person can open.

Here’s what IPsec does:

  • Keeps your data private by encrypting it so no one else can read it.
  • Checks for tampering to ensure no one has altered the data.
  • Verifies the sender to confirm the data is coming from the right person or device.

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.

How does Telnet work?

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.

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.

Meaning of DDoS attack

A DDoS attack, also known as a Distributed Denial of Service attack, is a major cyber threat that cybercriminals frequently launch against their targets. They overwhelm the victim’s server, system, or network due to this cyber-attack. A botnet of devices, commonly known as a DDoS attack, sends enormous amounts of fake traffic to the target as part of the DDoS attack. The victim is eventually saturated, rendering them unable to function.

What is the purpose of IPv6?

IPv6 is the sixth version of the Internet Protocol’s IP address. IPs are a set of rules that a device must follow when sending and receiving data from a host to a destination. As a result, you’ll need a list of recognizable hosts, their locations, IP addresses, and a communication path.

Since 1995, Internet Protocol version 6 has been in use. Despite this, IPv4 addresses have been hard to come by, among other issues. Despite this, the majority of companies continue to use the IPv4 protocol. Furthermore, according to an Internet Standard (IETF) issued in 2017, IPv6 utilization is likely to increase in the near future.
