The ICMP protocol is a network layer protocol that helps devices communicate error messages and operational information across a network. Think of it as a messenger that reports back when something goes wrong with data transmission. Unlike regular data protocols, ICMP focuses on network diagnostics and error reporting, making it essential for network troubleshooting and maintenance. When you use tools like ping or traceroute, you’re actually using how ICMP works to test connectivity between devices.…

What is subnetting? It is a way to divide a big network into smaller ones called subnets. This makes networks faster and easier to manage. Imagine sending a letter to a friend nearby. You want it to go straight to their town, not far away first. Subnets help data travel directly to the right place. By using a subnet and subnet mask, routers sort data quickly. This guide explains how does subnetting work in some…

The Internet Protocol (IP) is the fundamental building block of Internet communication. It’s like a postal system for the digital world, developed during the early history of Internet Protocol in the 1970s. IP addresses handle the addressing and routing of data packets across networks, ensuring they reach their intended destinations. So, how IP works? When you send data over the Internet, IP works by breaking down information into smaller packets, each containing the source and…

Simple Mail Transfer Protocol, or SMTP, is an internet protocol that serves as the backbone of email communication. Think of it as a digital postal service that ensures your emails reach their intended destination. This protocol acts as a standardized set of rules that email servers use to send, receive, and relay outgoing messages. When you click “send” on your email, SMTP springs into action, handling the complex process of moving your message across the…

Telnet protocol is a network protocol that enables remote access to computers over a network. It is one of the earliest protocols developed for the Internet, providing a text-based interface for remote communication. So, How Telnet work? It works by establishing a connection between two computers, which allows users to access and manage systems as if they were directly connected to them. However, its major drawback is that data transmission occurs in plain text, making…

Telnet is a simple tool that lets you connect to another computer over the internet or a local network. Curious about how does Telnet work? It is easy! You use a Telnet protocol on your device to communicate with a Telnet server far away. Once connected, you can type commands and control that computer like you are sitting in front of it. This works through a program called a Telnet client, available on Windows, Mac,…

Reverse DNS is a simple way to find a website’s name using its IP address. Imagine you have a phone number and want to know who it belongs to. This is what reverse DNS does for computers on the internet. It checks a special record called a PTR record to match the IP address, like 98.94.25.198, to a domain name. This process helps email servers trust your emails, improves website tracking, and keeps the Internet…

OSPF protocol is a link-state routing protocol designed for IP networks. It is like a GPS for data packets, helping them find the fastest and most efficient path through a network. Think of it as a smart traffic controller that constantly updates its map of the network, making sure data takes the best possible route. When comparing OSPF vs BGP, OSPF is typically used within an organization’s network, while BGP handles routing between different organizations.…

TCP/IP is a simple way for devices to send and receive data over the Internet. It breaks messages into small pieces called TCP IP packets, sends them to the right place, and puts them back together. Imagine mailing a letter split into parts—each part travels separately but arrives as one. The TCP IP model organizes this process into four easy steps, or layers, to make sure data moves smoothly between computers. This teamwork between TCP…
