An Elastic IP address is a static IPv4 address designed for dynamic cloud computing. An Elastic IP address is associated with your AWS account.

If tell you in simple words its the moveable ip.

Elastic IP addresses are used by AWS to manage its dynamic cloud computing services. Within the AWS infrastructure, customers have virtual private clouds (VPCs). Within the VPCs, users have instances. The Elastic IP address is what is used to advertise the data within the instance to the public internet.

EIP is associated with your account rather than instance. Even in the event of stop/start of the instance of the instance failure and you move to new instance you can still have the same public IP address. The advantage of an Elastic IP (EIP) is that you can move an IP address from one host to another.

Your Elastic IP address is a Public IP that you may allocate to your account. This may be associated to and from your Amimoto AMI instances as necessary.

Elastic IP addresses allow us to mask instance or availability zone failures by programmatically remapping your public IP addresses to any instance associated with your account.
