       Address allocation models for specific counts of fixed length
       subnets to downstream networks or devices from /48 down to /64 are
-      based on our imagination of how subnets are or should be allocated
-      within ipv4 networks.
+      based on design assumptions of how subnets are or should be
+      allocated and populated within ipv4 networks.
       Hierarchical allocation of fixed-length subnets requires
-      coordination between lower / intermediate / upper network elements
-      and has implict assumption that policies and size allocation at
-      the top of the hierarchy will accomidate all use cases with fixed
-      lenth subnet allocation.
-      Coordination with upstream network elements for the allocation of
-      fixed length subnets reveals topology and intent that may be
-      private in scope and which amounts to permission to build a
-      particular topology.
