Self Paced Lesson: Wednesday 2-17-2021 IP Addressing and DNS

Lesson Objectives: 

Upon successful completion of this lesson, you will be able to:

• Explain how IP addresses and the Domain Name System allow data to be “addressed” to a device on the internet.

Lesson Summary:

To understand the concept of an IP address, let’s take an example of how we mail letters through the postal service. Just like sending a letter to someone, we need to know their mailing address to be able to write their address properly so that it will be sent to its right destination. In the internet, the addressing system is similar. It is done through a set of protocols called the “Internet Protocol” or “IP.” The computer’s address is then called the IP address. This “address” refers to the set of unique numbers that gets linked to all of your online activities. These numbers are similar to your phone number or street address so it’s unique for each computer or device in the network.
