Cisco Packet Tracer is a tool built by Cisco and it provides network simulation to practice simple and complex networks. The main purpose of the Cisco Packet Tracer is to help students learn the principles of networking and demonstrate the networking concepts. 

Step 1: Open the Cisco Packet Tracer.

Step 2.: After opening the Cisco Packet tracer, add a router, 4 switches, 6 PCs, and a server to build a network for a small organization.

Router 1
Switch 4
Server 1
PC 6


Assume there’re four sections in this small organization:

1. Administration section
2. Accounts and Finance
3. Information Technology (IT).
4. Database section.

There are four different networks in this organization:

Step 3: Connect the router with 4 switches, 3 switches are connected with 2PCs each, and 1 switch is connected with the server using a cable.  There are four different networks in this organization:-,,, and 

Step 4: Give IP, subnet mask, default gateway, and DNS server to each PC and server in this network. To assign IP to each PC and server, click on each PC, go to Desktop, and then click on IP configuration.

Components IP Address Subnet Mask Default Gateway DNS server
        PC0 192.168..1.100

For example, For PC0:



Step 5: Now, configure the router according to the details given below and then turn on the port status. 


For example, For FastEthernet0/1:



Step 6: Now, we’ve to maintain the DNS server. For this click on the server, go to the services section, and then click on DNS. Turn on the DNS server, Enter any domain in the ‘Name’ section For eg: “” enter the IP address of the server in the ‘Address section’, and then click on save.

DNS Server


Step 7: Again click on the server, go to services, and then click on HTTP. Turn on the HTTP and HTTPS services. You can also edit the index.html file which will show when you search the domain you entered in DNS in the web browser.

Step 8: To check the connection between PCs present in different networks in this organization, you can use the ping command. Click on any PC, go to Desktop, and then click on the command prompt, enter the ping command, and check if they’re able to communicate with each other.

For example,  ping


Step 9: Click on any PC, go to the Desktop section, and then open the web browser. Enter the domain or address you’ve given in the DNS server and it will show the index.html file from HTTP services. 

Welcome to Packet Tracer


This is how a small network for an organization with 4 different sections is created. One can add as many sections and networking devices as one want.
