Creating an Elastic IPv6 prefix

To use an Elastic IPv6 prefix, the first step is to allocate it. This can be achieved via the [Portal][portal], the [CLI][cli] or the [API][api].

Create a Manual Elastic IPv6 prefix

To create an Elastic IPv6 prefix via the CLI, you need to specify IPv6 create --ipv6 and your chosen zone. This is what it looks like in the CLI:

# Mind the --ipv6 flag
exo compute elastic-ip create --ipv6 --zone at-vie-1

│ Zone           │ at-vie-1                             │
│ Type           │ manual                               │

The Elastic IPv6 prefix is visible in the CIDR field, while a reference IPv6 address within that prefix is displayed in the IP Address field. Note that the whole prefix is usable.

Create a Managed Elastic IPv6 prefix

Backed by a health check.

exo compute elastic-ip create \
 --ipv6 \
 --zone at-vie-1 \
 --healthcheck-mode tcp \
 --healthcheck-port 80

As seen above, in order to create a managed Elastic IPv6 prefix, you also have to provide the required health check parameters. Without those parameters, an Elastic IPv6 manual type will be created.
