IPv6 Reference
IP addresses let machines communicate across a network. DigitalOcean Droplets are assigned IPv4 addresses by default. Enabling IPv6 on a Droplet gives you access to its 16 additional IPv6 addresses.
The DigitalOcean API lets you manage DigitalOcean resources programmatically using conventional HTTP requests. All the functionality available in the DigitalOcean Control Panel is also available through the API.
doctl is a command-line interface for the DigitalOcean API and supports many of the same actions.
doctl supports enabling IPv6 addresses from the command line. See the doctl documentation or use doctl compute droplet-action enable-ipv6 --help for more information.
Use the DigitalOcean API to enable IPv6 addresses for Droplets.
Use doctl to enable IPv6 for Droplets from the command line.
