> In addition to have a single IPv6 address (/128) Instances in Basic Networking should
be able to have a IPv6 subnet, like a /60 for example routed to them.
> The mechanism for this is DHCPv6 Prefix Delegation. A DHCPv6 server can tell the Instance
which subnet is routed to it.
> On the physical router a (static) route needs to be configured to do this. So in Basic
Networking it will be up to the network admin to make sure the routes are present.
> The Management Server will pick a subnet for a Instance when needed and configure the
VR with the proper DHCPv6 arguments so that the right answer is provided to the Instance.
> For example when running containers it is very nice to have a subnet routed to your Instance
so you can give each container a unique IPv6 address.
