<t>
Address allocation models for specific counts of fixed length subnets
to downstream networks or devices from /48 down to /64 are based on
design assumptions of how subnets are or should be allocated and
populated within ipv4 networks.
</t>
<t>
Hierarchical allocation of fixed-length subnets requires coordination
between lower / intermediate / upper network elementss. It has
implict assumption that policies and size allocation allowed the top
of the hierarchy will accomodate present and future use cases with
fixed lenth subnet allocation.
</t>
<t>
Coordination with upstream networks across administrative domains for
the allocation of fixed length subnets reveals topology and intent that
may be private in scope. Policies for hierarchical allcation are applied
top-down and amount to permission to build a particular topology (for
example mobile device tethering, virtual machine instantiation, containers
and so on).
