Paper 1
Revise: The Internet and CloudA browser, however, needs the web server's IP address to contact it. A Domain Name Service (DNS) connects these two forms of address by looking up a domain name and returning its corresponding IP address.
An Internet Protocol address assigned to a device's network connection, used to identify it and help deliver data to the correct destination across networks.
For DNS, state that the domain name in the URL is looked up and the corresponding IP address is returned. DNS does not send the web page itself.
Distinguish the roles: IP addresses help deliver data across networks; MAC addresses identify network interfaces for delivery within a local network.
You do not need to explain static versus dynamic or public versus private IP addresses for this lesson.
