IP addressing scheme for UTeM network

    


 IP addressing scheme for UTeM network 

(Computer Centre to the 10 subnetworks )

 using subnetting 


  • Calculation of the IP subnetting 

            IP address = 203.100.50.0

            Quantity of subnet = 2 ^ 4 = 16 subnets

            (Need at least 4 bits to represent the 10 subnets)

            Subnet mask = 255.255.255.240

            Take from 240

            So, 240 is equal to 11110000 

            Then, the quantity of bits borrowed = 4 bits

            Quantity host per subnet = 2 ^ 4 - 2 = 14 hosts

            *Note that the usable host addresses within each subnet will range from the network address + 1                                             to the broadcast address - 1.


  • Network address, broadcast address & the range of usable IP addresses for the Computer Centre. 

            Network address: 203.100.50.160

Figure 1 Packet Tracer Software that being used in the project : Packet Tracer Description       Packet Tracer is a network simulation and visualization tool developed by Cisco Systems. It is widely used for designing, configuring, and troubleshooting computer networks. It provides a virtual environment where users can create network topologies and simulate network behavior.       Packet Tracer offers a wide range of network devices such as routers, switches, hubs, firewalls, access points, and end devices like PCs, laptops, servers, and phones. These devices can be dragged and dropped onto the workspace to create a network topology.      With Packet Tracer, you can design complex network topologies by connecting devices using various types of network cables. You can create LANs, WANs, VLANs, and wireless networks. The tool supports both physical and logical connections between devices.      Packet Tracer allows you to configu...

LAN network design and infrastructure of UTeM’s network connecting Computer Centre to the 10 subnetworks

i) Networking devices   The network devices that we will be using will consist of 5 routers and multiple switches.  The network will be separated into the networks.   1st router - Computer Centre (main network) 2nd router - FTMK (Subnet 1) 3rd router - Canselory (Subnet 2) 4th router - FKE, FKEKK, FKM, FKP (Subnet 3 - 6) 5th router - Post Grad, Registrar, Library, Sport (Subnet 7 - 10) The suggested total number of network devices used to create the network designs are: 5 Core Layer Switches 5 Distribution Layer Switches 17 Access Layer Switches 4 Routers This is not taking into account the network devices used for the Computer Center which will be in its own separate post. ii) Topology This is the main topology of the network. Every router will connect back to Computer Centre and in turn will connect to the ISP. The reason we gave FTMK its own separate router is because of the large amount of PCs used. Canselory will also have its own separate router for security re...
