The bounds information is useful when making an authoritative response, as it can be used to determine whether the query name is at or beneath a delegation point. The other data in the ``Bounds`` object is useful for making on-the-fly DNSSEC signatures. The left bound of *name* is *name* itself if it is in the zone, or the greatest predecessor which is in the zone. The right bound of *name* is the least successor of *name*, or ``None`` if no name in the zone is greater than *name*. The closest encloser of *name* is *name* itself, if *name* is in the zone; otherwise it is the name with the largest number of labels in common with *name* that is in the zone, either explicitly or by the implied existence of empty non-terminals. The bounds *is_equal* field is ``True`` if and only if *name* is equal to its left bound. The bounds *is_delegation* field is ``True`` if and only if the left bound is a delegation point.
