**To view the attributes of the domain name associated with an elastic IP address**

The following ``describe-addresses-attribute`` examples return the attributes of the domain name associated with the elastic IP address.

Linux::

    aws ec2 describe-addresses-attribute \
        --allocation-ids eipalloc-abcdef01234567890 \
        --attribute domain-name
        
Windows::

    aws ec2 describe-addresses-attribute ^
        --allocation-ids eipalloc-abcdef01234567890 ^
        --attribute domain-name
        
Output::

    {
        "Addresses": [
            {
                "PublicIp": "192.0.2.0",
                "AllocationId": "eipalloc-abcdef01234567890",
                "PtrRecord": "example.com."
            }
        ]
    }
