Claim 14:
15. A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, the operations comprising:
generating a hierarchical structure of nodes from a specified origin internet address block to a specified lower level of internet address blocks of the specified origin internet address block that is lower than a level associated with the specified origin internet address block;
for each node in the hierarchical structure of nodes, where the node comprises at least one internet address, of an internet address block associated with the node, that is assigned to at least one respective device:
marking the node as used,
in response to determining that an origin node of the hierarchical structure of nodes associated with the specified origin internet address block is not marked as used, marking the origin node as used,
marking all nodes in a path between the origin node and the node as used, and
marking any nodes in the hierarchical structure of nodes that are descendants of the node as used;

determining a count of unused internet address blocks of the hierarchical structure of nodes that are not assigned to any devices based on nodes below the origin node that are not marked as used; and
displaying, via a display device, a user interface comprising the count of unused internet address blocks.
