Public IP for my ec2-instance is missing

Question

When I disassociated the elastic IP from an instance, my public IP was missing, due to which I am unable to launch my instance. Could you please assist to get my public IP. 

Answer 1

Reason:  This occurs due to the disassociation of your elastic IP.

TL/DR:

Attach a new elastic IP to your AWS instance. 

Solution:

There are two ways to resolve this issue,

1. Create a new elastic IP and then attach it to your instance.

2. You can request AWS to assign a new public IPV4 address to your instance.

For that, Go to instance>>Actions>>Networking>>Manage IP address 

Click on Assign new IP will assign you with a new public IP from AWS.
