2/ Protocols: These are the rules that govern how data travels through the ports. Some key players:
• TCP (Transmission Control Protocol): Reliable, like sending a signed package 📦.
• UDP (User Datagram Protocol): Fast but no guarantees, like texting in a hurry! 📲

1/ Ports: Think of them as doors on your device that let data in and out. Some doors are always open for specific tasks, like:
• 📨 Port 25: Email (SMTP)
• 🌐 Port 80: Websites (HTTP)
• 🔒 Port 443: Secure web (HTTPS).

Without these “doors,” communication would be chaos! 🙅‍♂️

5/ Learning about IPv6 has shown me how IT evolves to meet challenges. Understanding its role helps build skills for a connected future. 💡

Have you encountered IPv6 in action? Drop your thoughts below! ⬇️ #IPv6 #ITTraining

4/ The transition to IPv6 has been slow, as many networks still rely on IPv4. But with over 7 billion people online, IPv6 is essential for future scalability. 🌍

3 / IPv6 isn’t just about size; it’s smarter:
• Better security 🔒
• Efficient routing 🚀
• Support for IoT devices 🌐
It’s designed to handle the demands of a connected world.

2/ Enter IPv6, the future of IP addresses! 🌟 It uses a 128-bit addressing system, providing billions of unique addresses for our growing number of devices.

An IPv6 address looks like:
2001:0db8:85a3:0000:0000:8a2e:0370:7334

Compare that to IPv4’s:
192.168.1.1

1/ IPv5 was an experimental protocol called Stream Protocol (ST). It was designed in the 1980s for streaming audio & video but used the same 32-bit addressing as IPv4. This limitation made it obsolete as the internet grew. 🚫

7/ 🛠️ Why It Matters: Understanding IPv4 is crucial for networking and IT professionals. It lays the foundation for managing networks, troubleshooting, and ensuring seamless communication between devices. 💼

Andre Lawrence @techandre876.bsky.social · Nov 25

6/ 📉 Running Out of IPv4: With only about 4.3 billion addresses, IPv4 is limited. As more devices connect to the internet, we’ve had to adopt IPv6, which offers a much larger pool of addresses. But IPv4 is still widely used! 🌟

5/ 💡 Subnetting: Subnetting is a way to divide a large network into smaller segments, improving efficiency and security. It’s a critical skill for anyone working in IT. For example, a subnet mask like 255.255.255.0 tells the system how to split networks. 🔗

4/ 🚦 Private vs. Public: Not all IPv4 addresses are used online. Private addresses (e.g., 192.168.x.x) are used within local networks, while public addresses are used to connect to the internet. Your router manages this with NAT (Network Address Translation). 🌐

Andre Lawrence @techandre876.bsky.social · Nov 25

3/ 🗺️ Address Classes: IPv4 is divided into five classes (A, B, C, D, and E), but the most commonly used are A, B, and C. These classes determine the range of addresses and are used to organize networks based on size and needs.

1

Andre Lawrence @techandre876.bsky.social · Nov 25

2/ 🧩 How It Works: IPv4 addresses are made up of 32 bits, divided into four 8-bit segments called octets. Each octet can range from 0 to 255, making IPv4 addresses look like this: 192.168.1.1. These addresses ensure that data knows where to go and come from. 📦➡️

1/ 🌍 What is IPv4? IPv4, or Internet Protocol version 4, is the backbone of how devices communicate on the internet. It’s a system of numerical addresses that uniquely identify every device connected to a network. Think of it as the “home address” for your computer or phone. 🖥️📱
