A character set defined by ISO8859-1.
 Legacy Resource
Internet number resources that were distributed before (or outside of) the current system of hierarchical distribution by the Regional Internet Registries (RIRs).
 Less Specific
Both IPv4 and IPv6 addresses are structured in hierarchies with 0/0 and ::/0 as the roots of the structures. The root objects have child objects forming the next layer in the hierarchical structure. The root objects are therefore the parents of the child objects. This is repeated throughout the structure as more layers are added. Parent objects are considered to be less specific than the child objects. Child objects are considered to be more specific to the parent objects.
