Hey friend!
Admittedly it is difficult to eyeball this as the way it is configured varies not only by distro, but by version. Assuming you’ve not enabled private networking though, that should then be the anchor IP in case you ever use our floating IPs. Our floating IPs communicate to the droplets over a private network rather than the droplet’s public IP.
