Final answer:
Elastic IP addresses (EIPs) are per account, per region. They have a cost if not associated with anything and are not static IPv6 addresses.
Step-by-step explanation:
The correct statements about Elastic IP (EIP) are:
- EIPs are per account, per region: Elastic IP addresses are unique to an AWS account and can be associated with resources in a specific region.
- EIPs have a cost if not associated with anything: If an Elastic IP is not associated with any running instance, it may incur charges.
- EIPs are static IPv6 addresses: Elastic IP addresses only support IPv4 addressing.
