Why does my Droplet have a US-based IP address when I created it in a different region?

The IP address block information for a Droplet shows a US location because the IP block belongs to DigitalOcean which is headquartered in New York City. You have to review the geolocation for the IP address instead to see the location of where you created the server.

Older Droplets that did not have VPC enabled prior to October 2020 cannot be added to a VPC network without changing its IP address.
Edit your Droplet’s sshd_config file to change its SSH port.
You cannot retain a Droplet’s IPv4 when you transfer the Droplet to a new region. Use a reserved IP address to maintain a static IP address.
