Yes it’s doable. The droplet listing API call will get you all droplets in the account and their respective IPs. So from the droplet itself get the IP:

# Make sure to: yum install net-tools
IP=$(ifconfig eth0 |grep "inet "|awk '{print $2}')

Then call the API to get the droplet list and match the droplet with the IP from above.

JSON=$(curl -X GET -H "Content-Type: application/json" -H "Authorization: Bearer $API_KEY" "https://api.digitalocean.com/v2/droplets?page=1&per_page=1")

You’d need to use the DO API v2 for this. A simple curl to the API would get you the droplet name.
