Introduction

This tutorial provides a step-by-step guide on configuring a Web Server and DNS Server using Cisco Packet Tracer. Understanding these configurations is crucial for network administrators as they establish the foundation for web applications and domain name resolution within a network.

Step 1: Setting Up the Web Server

1. Open Cisco Packet Tracer and create a new project.
2. Add a Server Device:
   • Locate the server device in the device panel.
   • Drag and drop it onto the workspace.
3. Configure the Server:
   • Click on the server and navigate to the "Config" tab.
   • Under "Global Settings," assign an IP address, subnet mask, and default gateway.
   • Example configuration:
     • IP Address: 192.168.1.2
     • Subnet Mask: 255.255.255.0
     • Default Gateway: 192.168.1.1
4. Enable the HTTP Service:
   • Click on the "Services" tab.
   • Enable the HTTP service by clicking on the checkbox.
   • Optionally, configure the web page content in the HTTP configuration section.

Step 2: Setting Up the DNS Server

1. Add a DNS Server:
   • Drag a second server onto the workspace for DNS configuration.
2. Configure the DNS Server:
   • Click on the DNS server and go to the "Config" tab.
   • Assign an IP address similar to the web server but different.
   • Example configuration:
     • IP Address: 192.168.1.3
     • Subnet Mask: 255.255.255.0
     • Default Gateway: 192.168.1.1
3. Add DNS Records:
   • Navigate to the "DNS" tab within the server configuration.
   • Create a new record by entering a hostname (e.g., www.example.com) and the corresponding IP address of the web server (192.168.1.2).
   • Click on "Add" to save the record.

Step 3: Testing the Configuration

1. Connect Devices:
   • Add a PC to the workspace and connect it to the same network as the servers.
2. Configure the PC:
   • Assign an IP address to the PC, ensuring it is in the same range as the servers.
   • Example configuration:
     • IP Address: 192.168.1.4
     • Subnet Mask: 255.255.255.0
     • Default Gateway: 192.168.1.1
3. Test the Web Server:
   • Open the web browser on the PC and enter the IP address of the web server (http://192.168.1.2).
   • Verify that the web page loads as expected.
4. Test the DNS Resolution:
   • In the PC command prompt, use the command ping www.example.com.
   • Ensure that the correct IP address is returned, confirming that DNS resolution works.

Conclusion

You have successfully configured a Web Server and DNS Server using Cisco Packet Tracer. This setup allows devices on the network to access web services and use domain names for navigation. As a next step, consider exploring additional services like FTP or DHCP for a more comprehensive network setup.
