ARP analysis
Queen of Networks 👑@NetworkQueenX
Ever wonder how your phone actually "finds" the Wi-Fi router? It’s not magic it’s ARP. Watch me break down the Inbound vs. Outbound PDU logic on a Cisco Router. We’re moving from "Broadcast" to "Unicast" to get this connection stable. #Networking #CCNA #Cisco

So I just completed the Pre Security course on TryHackMe .
Learned cybersecurity basics, networking fundamentals & weaknesses, web attacks, and how to work with Linux and Windows from a security angle. Which I was already familiar with some of the concepts. It was a lightweight experience.
Expect more of this 🙏🏾. Everyone clapped for me 👏🏾👏🏾 and tell me Weldone.

Building networking fundamentals the right way: two LANs, one router, clear traffic flow. Simple labs teach deeper understanding than complex diagrams.
This is how inter-network communication really works.

Hosts are the devices that actually participate in communication.
Once I saw it in a lab, it finally clicked.

Cybersecurity beginners should start with fundamentals:
* Intro to Cybersecurity (Cisco)

* CIA Triad overview

No cable. No signal. No network.
Layer 1 decides everything above it.

SOHO users often use ADSL because download speeds are higher than upload speeds.
This fits their usage pattern, they usually download more than they upload.

The OSI model isn’t something engineers memorize.
It’s how we stop guessing when things break.
One problem. One layer at a time.

The OSI model isn’t something engineers memorize.
It’s something they use to stop guessing when things break.
Instead of panic, you ask one question: which layer is failing?

Motivated by this boss @akintunero Network Engineering design idea, I successfully designed an enterprise wan topology and implemented the following technologies across the topology
👉 GRE over IPsec
👉 Dynamic Routing (OSPF)
👉 Inter-VLAN routing
👉 ACL and NAT overload

For those asking me for Network Engineering project ideas: Build a Banking WAN: 1 HQ + 5 branches. HQ provides Internet + secure services (VPN, routing, redundancy) to all branches. Technologies to make use of: VLANs, OSPF, NAT, IPsec, and ACLs. Have fun building

OSPF Areas >>> explained simply
Large networks need order.
OSPF uses areas. Area 0 is the backbone. ABRs connect everything cleanly.
That’s how routing stays stable and scalable in real enterprise networks.

Intermediate cybersecurity topics worth your time:
* Network security fundamentals
* Firewalls & IDS/IPS
* Security policies & enforcement
These are the building blocks of real security work.

Why OSPF shows up in real enterprise networks:
reliability, speed, and scalability.
Understanding OSPF is one of those moments where networking starts to feel real.

OSPF likes order.
That’s why it divides large networks into areas to reduce chaos, improve stability, and allow networks to scale cleanly.
This is how real networks stay manageable.
