Refer to the following guide to learn how to use IAM in the cloud\ <https://scribehow.com/shared/Creating_an_IAM_User_and_User_Group_in_AWS_Management_Console__hWNiiXlcRJKFqYZZEJD-cg>
Sign in to **AWS Management Console** as an **IAM User** **Pre-requisite** - Ensure you have selected the AWS region closest to your location\ For this guide, we will be using us-east-2 (Ohio) as a preferred choice
Type **EC2** in the search bar and click on **EC2** to view the EC2 Dashboard
**What is Amazon EC2?** Amazon EC2 is a cloud computing service by AWS, offering resizable virtual servers called instances. It enables users to run applications, scale resources as needed, and pay only for what they use.
On the EC2 dashboard click on **Instances** from the left bar to view the EC2 instances
Refer to this guide to learn how to create an EC2 instance\ <https://scribehow.com/shared/AWS__Creating_your_first_EC2_Instance__Xcu7ZVCdRfWx56YVktKgbQ>
Select the **Public-EC2-instance** instance
Scroll the page to view the **Public IPv4 address**
**What is Public IPv4 address?** A Public IPv4 address is a unique numerical label assigned to a device connected to a network, allowing it to communicate with other devices over the internet. It serves as an identifier for the device and enables communication between different systems across the internet.
On the top right corner click on the **Instance state** dropdown and select the option **Stop instance**
**Stop instance** wizard will open, click on the **Stop** button
On the top right corner click on the **Refresh instance** widget to refresh the instance status
Scroll the page to the Public IPv4 address, and you will notice that there is no **Public IPv4 address** available as we have stopped the instance but the Private IPv4 address is visible
On the top right corner click on the **Instance state** dropdown button and click on the option **Start instance**
On the top right corner click on the **Refresh instance** widget to refresh the instance status
Scroll the page to the **Public IPv4 address**, and you will observe that the Public IPv4 address is visible and has been updated with a new value but the Private IPv4 address is still constant
**What's the reason for the change in the Public IPv4 address?** The Public IPv4 address changed likely due to a refresh or reboot of the EC2 instance, or because it was assigned a new address by the AWS infrastructure.
Congratulations on successfully exploring the EC2 public and private IPv4 addresses in AWS, and completing this lab. Well done!
