INTERNET INRAPRICE USING LAN | Networking

Hello Everyone,

It has been some time since last I posted anything, but I am happy to say the reason for this was that I was busy preparing for one of my Cisco CCNP VPN exam. I am also happy to report that I did pass the exam after many hours of hard work and thus took a little break from posting and labbing things up.

Now That I am back I am doing a little revision on Unicast and Multicast. For Those who don’t know what this is don’t stress I will have a brief explanation below followed with some more technical posts later to come.

Unicast:

Unicast IP address are those IP addresses, which go one to one. Or in more simple explanation one device speaking to another typically used in routing and switching to update the devices with information of each other.

Multicast:

Multicast IP addresses are used when one devices need to communicate with many other. For an example like routing update information. If there is someone out there following my pasts you will notice in previous posts setups like GETVPN and EIGRP use Multicast to send updates to devices that belong to a Multicast group, hence one to many communication. the IP address ranges is typically 224.0.0.0 239.255.255.255

I have also attached a picture to explain traffic flows.

As always please leave a comment or a like! If you have any questions on this topic please let me know. More to come soon.

The ISP sector runs heavily on efficient routing, user authentication, and traffic management, all of which are core strengths of MikroTik systems. Having practical experience in these areas allows fresh graduates and diploma holders to step directly into technical roles within telecom and networking companies.

Starting with MikroTik RouterOS involves understanding the basics of IP networks and setting up WinBox, the graphical configuration tool. Beginners should practice setting up basic DHCP servers, wireless access points, and simple firewall rules in a lab environment before managing live networks.

MikroTik routers offer enterprise-grade routing features at a fraction of the cost, making them ideal for both small businesses and advanced home networks. Key benefits include powerful bandwidth management (QoS), robust firewall security, VLAN configuration, and stability.

Passing CCNA isn't just about reading — it's about building hands-on muscle memory with real networking concepts. Here's a practical approach:

Start with the fundamentals. Understand OSI and TCP/IP models thoroughly before jumping into configurations — everything else builds on this.

Use official resources. The Cisco CCNA 200-301 Official Cert Guide is a solid structured reference.

Practice with simulators. Tools like Cisco Packet Tracer or GNS3 let you configure routers and switches without needing physical hardware.

Take advantage of free training. Cisco Networking Academy offers free courses aligned directly with the exam blueprint.

Do timed practice tests. This helps you get used to the exam's pace and question style before the real thing.

A lot of first-time candidates get confused about who actually administers the CCNA exam. Here's the simple breakdown:

Cisco Systems owns the certification — they design the curriculum, set the passing standards, and issue the certificate.

Pearson VUE is the third-party testing vendor that physically (or virtually) delivers the exam.

This means when you register, you'll first create an account on Cisco's certification portal, but the actual exam booking, scheduling, and test-day experience happens through Pearson VUE's system.

You have two options for taking the exam:

In-person at an authorized test center — a standard proctored environment.

Online proctored exam — take it from home under webcam supervision, provided your system meets Pearson VUE's technical requirements.

If you're stepping into the world of networking, you've probably come across the term CCNA (Cisco Certified Network Associate). It's one of the most recognized entry-to-associate level certifications in the IT industry, offered by Cisco Systems.

CCNA validates your knowledge in areas like network fundamentals, IP connectivity, IP services, security fundamentals, automation, and programmability. Unlike older versions that had multiple specialized tracks, the current CCNA is a single, unified exam — 200-301 CCNA — covering a broad range of networking topics.

Why does it matter? Because networking is the backbone of every modern business. Whether it's a small office or a global enterprise, someone has to design, configure, and troubleshoot the network that keeps everything connected. A CCNA certification tells employers you have the foundational skills to do exactly that.
