- ``ipv6_dhcpv6-stateful``: Configure this interface with ``dhcp6``
- ``ipv6_dhcpv6-stateless``: Configure this interface with SLAAC and DHCP
- ``ipv6_slaac``: Configure address with SLAAC

When making use of ``dhcp`` types, no additional configuration is needed in
the subnet dictionary.
When making use of ``dhcp`` or either of the ``ipv6_dhcpv6`` types,
no additional configuration is needed in the subnet dictionary.

Using ``ipv6_dhcpv6-stateless`` or ``ipv6_slaac`` allows the IPv6 address to be
automatically configured with StateLess Address AutoConfiguration (`SLAAC`_).
SLAAC requires support from the network, so verify that your cloud or network
offering has support before trying it out. With ``ipv6_dhcpv6-stateless``,
DHCPv6 is still used to fetch other subnet details such as gateway or DNS
servers. If you only want to discover the address, use ``ipv6_slaac``.
