A packet tracer is a simulation tool that helps to configure and visualize a network in logical and physical modes. The objective is to configure a small office Local Area Network (LAN) where 5 PCs and 1 printer are connected to a wireless router through wires. 1 mobile, and 1 tablet PC are connected to the same wireless router which acts as a DHCP server and default gateway provided by Internet Service Provider (ISP) to connect all those devices to the internet. 

Configure those devices with the IP addresses 

Default gateway- 192.168.1.1/24 

Reserve IP addresses for those devices through DHCP 

PC1- 192.168.1.10/24 

PC2- 192.168.1.11/24 

PC3- 192.168.1.12/24 

PC4- 192.168.1.13/24 

PC5- 192.168.1.14/24 

Printer - 192.168.1.253/24 

Wireless Router configuration would be - SSID- pollyvacherwireless, with WPA2 Enterprise AES with shared key - P0llyVch3r. (Hint: you may need to set up a Radius AAA server). You then test at least two pairs of device-to-device connections using proper networking command(s) and check that different device can communicate with each other. 

3. Install 1 DNS Server (192.168.1.2/24) and 1 HTTP server (192.168.1.3/24) into the previous office network. Update the DHCP configuration to reserve IP addresses for the new servers. On the DNS Server, add an A record to the mapping between www.pollyvacher.ac.uk and the HTTP server. Test the DNS resolution for www.pollyvacher.ac.uk using proper networking command(s) on 

at least 1 PC and 1 mobile device. Finally, use the web browser to open www.pollyvacher.ac.uk on at least 1 PC and 1 mobile device.
