How to get Public IP via AWS CLI while launching

My AWS Command is:

> aws ec2 run-instances --image-id ami-346b2354 --count 1 --instance-type c4.large --key-name my-cali-key --security-group-ids sg-a168c7c4

When I trigger this, the JSON data that it returns has only the Private IP address and NOT the Public IP address.

 ................ DATA  OMITTED................... 

                "Groups": [
                    {
                        "GroupName": "launch-wizard-1", 
                        "GroupId": "sg-a168c7c4"
                    }
                ], 
                "SubnetId": "subnet-cb2524ae", 
                "OwnerId": "012710546082", 
                "PrivateIpAddress": "172.31.17.252"
            }

(Image) Browser look of the same instance with Public IP

However when I see in the browser I immediately notice a Public IP address being associated automatically. How Can I fetch the public IP of launched instances? Kindly do not get confused with elastic-IP and its association with instances. I know to associate an elastic-IP but the need here is different.

aws ec2 describe-instances \
  --query "Reservations[*].Instances[*].PublicIpAddress" \
  --output=text

Another Way is 

curl --silent http://ipecho.net/plain

This will return Public IP of instance
