Configure a range of server types
This is best done with:
Cisco Packet Tracer
Assessment
Report with screenshots
This report will be longer than one page with all the screenshots
Centres can use simulation software.
Domain Name System (DNS)
Web Server

Dynamic Host Configuration Protocol (DHCP)
file server
You will be configuring two main types of servers: Domain Name Server (DNS) and a Web Server.
Both form the basis of how we use the internet.
The DNS is what allows us to enter www.google.com and it finds the webserver. The DNS has a table of each IP Address and each domain.
For example, if you type: google.com, the web browser (Chrome or Safari) goes out through the router to a DNS and asks:
a) "Do you know this domain?"
b) "The DNS says, yes, I know it's at this IP Address: 172.217.169.78"
c) The request then goes through a series of DNS's until it gets to the webserver (172.217.169.78) that has it's own unique IP address
d) The web page comes back with what you asked for
Try this out on your own computer:
1 - On a Windows machine (Macs, use these intructions), go to the Start Menu and type CMD
2 - Type: ping google.com
3 - The resulting set of numbers separated by full stops ( . ) is the physical number of the server
Every server / device / computer on the internet has it's own unique IP address.
Now, open a web browser and type the IP address: 172.217.169.78 in the address bar and press enter
What happens?
This is how DNS and HTTP/HTTPS works
Often times the DNS Server inside a company, is the same computer as the web server.
