TCP/IP Basics and Common Issues

The Transmission Control Protocol/Internet Protocol, or TCP/IP, is the backbone of the internet and plays a fundamental role in connecting devices and facilitating data transfer across the world. Understanding TCP/IP basics and common issues is essential for anyone involved in network management, as it enables them to troubleshoot problems and maintain a stable network. In this article, we will delve into TCP/IP fundamentals, explore common issues that arise, and discuss how TCP monitoring can help in maintaining network health.

TCP/IP Basics

TCP/IP is a suite of communication protocols that allows data to be transmitted over networks. It is a layered protocol, with four primary layers:

Exposing the Impact of DNS Propagation

What is DNS Propagation and what can it do?

DNS Propagation is a process by which changes to Domain Name System (DNS) records are reflected across the internet. It is the time it takes for all DNS servers in the world to receive and apply updates about a certain domain. As such, it is a critical part of any website’s success and the functionality of a domain.

6 Critical DNS records You Need to Know

DNS records are an essential component of the internet infrastructure. They are responsible for resolving domain names into IP addresses that computers can use to communicate with each other. Without DNS records, navigating the web would be a lot harder. In this blog post, we’ll look at six critical DNS records you need to know. So, let’s start!

A Record (Address Record)

The A record is the most basic DNS record. It maps a domain name to an IP address. Whenever a user enters a domain name into their browser, the browser sends a request to the DNS server to resolve the domain name into an IP address using the A record. This record serves to point a domain name to a domain name’s IP address, allowing users to access a website.

Increase System Uptime with DNS Monitoring

Keeping your data and information secure is essential. DNS monitoring is a powerful tool that enables organizations to monitor their own DNS server to quickly detect potential threats and vulnerabilities, proactively respond to malicious activities, and optimize their website or network performance. Do you want to learn more about it? Great! You are in the right place. But let’s first explain briefly what DNS is.

Explain Briefly What DNS Is

When a hostname, such as squadrainformatica.com, is typed into a web browser’s address bar, a process known as resolution occurs to convert the hostname into an IP address (e.g., 92.38.169.175). This process happens so quickly that it is usually invisible to the user, but it involves four different types of DNS servers working in unison to achieve the correct resolution.

Anycast DNS: Definition & Benefits

Anycast DNS is an efficient and robust DNS architecture that gives your business increased performance, network-level security, automated routing, and cost savings. Let’s now explore a little bit more.

What is Anycast DNS?

Anycast DNS is a type of Domain Name System (DNS) architecture that enables the routing of user requests to the closest, most accessible server. It works by assigning multiple hosts with the same IP address and broadcasting them across multiple locations. As a result, when a user queries for a name resolution, their request is broadcast to all available DNS servers and routed quickly to the best location for service. This allows for greater scalability, quicker responses, and improved performance. Additionally, since all of the hosts have the same numerical address, traffic is automatically directed to the nearest server hosting the website or service, reducing latency and eliminating the need for manual routing.

All you need to know about IPv4

Are you looking to get the most out of your network? Then, IPv4 is the way to go! It is the most widely used protocol for internet communication, providing a secure, flexible, and fast connection. In this blog post, we’ll explore the advantages of using IPv4, how it affects networks, and the importance of DHCP. So if you’re looking to get the most out of your network, read on to learn more about IPv4!
