A subnet, or subnetwork, is a network within another network meant to simplify routes between devices on a network.

With subnets, you can break larger networks up into smaller networks, which increases the number of devices that can connect to the internet. The subnet is usually associated with a subnet mask.

You can assign a Droplet’s IPv6 address to a subnet, which takes up to 16 bits in length.

Each Droplet with IPv6 enabled is allotted a /124 subnet, which contains 16 configurable IPv6 addresses. By default, we configure one IPv6 address in this range for the Droplet, and you can configure additional IPv6 addresses at any time.

We support a maximum of 16 addresses (a subnet mask of /124) per Droplet. Additional addresses are not available.
