🔍 Day 15 – Networking Challenge
Today’s focus: ARP Protocol
ARP maps IP addresses to MAC addresses, helping devices find each other on a local network.

🚪 Day 14 – Networking Challenge
Today’s focus: Gateway Networks 🌐
A gateway connects local networks to the Internet — acting as the bridge that lets data flow in and out of your network.

🧠 Day 6 – Networking Challenge
Today’s focus: Relearning & Reflection
Taking time to review everything I’ve learned so far — from network types to home technologies.
Revisiting concepts helps strengthen understanding and build a solid foundation for the best

[Cyber_Dev @ogunzsunmi1]

🌐 Day 12 – Networking Challenge
Today’s focus: Static vs Dynamic IP Addressing
Static IPs are fixed and reliable, great for servers. Dynamic IPs are assigned automatically via DHCP, making large networks easier to manage.

#Day12 #NetworkingChallenge #IPAddresses #Networking

[Cyber_Dev @ogunzsunmi1]

🌍 Day 11 – Networking Challenge
Today’s focus: IPv6 Addressing
IPv6 uses 128-bit addresses written in hexadecimal. You can shorten them by removing leading zeros or using “::” once for consecutive zeros — simple rules, powerful scale!

#Day11 #NetworkingChallenge #ipv6

[Cyber_Dev @ogunzsunmi1]

🌐 Day 10 – Networking Challenge
Today’s focus: IPv4 & Network Segmentation
IPv4 gives every device a unique address, while segmentation (subnetting) divides large networks into smaller, secure, and efficient parts.

🌍 Day 9 – Networking Challenge
Today’s focus: Internet Protocols (IP)
Internet Protocols define how data is addressed and sent across networks. Every device uses an IP address to identify itself, making global communication possible.
