METHODS

       For details on what these Methods implement, see the Test Specifications document
       (https://github.com/zonemaster/zonemaster/blob/v2022.2.2/docs/specifications/tests/MethodsV2.md).

       get_parent_ns_ips($zone)
           [External]

           This Method will obtain the name servers that serves the parent zone, i.e. the zone
           from which the Child Zone is delegated from.

           Takes a Zonemaster::Engine::Zone object ($zone).

           Returns an arrayref of Zonemaster::Engine::Nameserver objects, or `undef` if no parent
           zone was found.

       _get_oob_ips($zone, $ns_names_ref)
           [Internal]

           This Method will obtain the IP addresses of the Out-Of-Bailiwick name servers for the
           given zone and a given set of name server names.

           Takes a Zonemaster::Engine::Zone object ($zone) and an arrayref of
           Zonemaster::Engine::Nameserver objects ($ns_names_ref).

           Returns an arrayref of Zonemaster::Engine::Nameserver objects.

       _get_delegation($zone)
           [Internal]

           This Method will obtain the name server names (from the NS records) and the IP
           addresses (from Glue records) from the delegation of the given zone from the parent
           zone.  Glue Records are address records for In-Bailiwick name server names, if any.

           Takes a Zonemaster::Engine::Zone object ($zone).

           Returns an arrayref of Zonemaster::Engine::Nameserver objects, or `undef` if no parent
           zone was found.

       get_del_ns_names_and_ips($zone)
           [External]

           This Method will obtain the name server names (from the NS records) and the IP
           addresses (from Glue Records) from the delegation of the given zone from the parent
           zone.  Glue Records, if any, are address records for name server names. Also obtain
           the IP addresses for the Out-Of-Bailiwick name server names, if any.  If the Glue
           Records include address records for Out-Of-Bailiwick name servers they will be
           included twice, unless identical.

           Takes a Zonemaster::Engine::Zone object ($zone).

           Returns an arrayref of Zonemaster::Engine::Nameserver objects, or `undef` if no parent
           zone was found.

       get_del_ns_names($zone)
           [External]

           This Method will obtain the name server names of the given zone as defined in the
           delegation from parent zone.

           Takes a Zonemaster::Engine::Zone object ($zone).

           Returns an arrayref of strings, or `undef` if no parent zone was found.

       get_del_ns_ips($zone)
           [External]

           This Method will obtain the IP addresses (from Glue Records) from the delegation of
           the given zone from the parent zone.  Glue Records are address records for In-
           Bailiwick name server names, if any. Also obtain the IP addresses for the Out-Of-
           Bailiwick name server names, if any.

           Takes a Zonemaster::Engine::Zone object ($zone).

           Returns an arrayref of strings, or `undef` if no parent zone was found.

       get_zone_ns_names($zone)
           [External]

           This Method will obtain the names of the authoritative name servers for the given zone
           as defined in the NS records in the zone itself.

           Takes a Zonemaster::Engine::Zone object ($zone).

           Returns an arrayref of strings, or `undef` if no parent zone was found.

       _get_ib_addr_in_zone($zone)
           [Internal]

           This Method will obtain obtain the address records matching the In-Bailiwick name
           server names from the given zone.

           Takes a Zonemaster::Engine::Zone object ($zone).

           Returns an arrayref of Zonemaster::Engine::Nameserver objects, or `undef` if no parent
           zone was found.

       get_zone_ns_names_and_ips($zone)
           [External]

           This Method will obtain the name server names (extracted from the NS records) from the
           apex of the given zone.  For the In-Bailiwick name server names obtain the IP
           addresses from the given zone. For the Out-Of-Bailiwick name server names obtain the
           IP addresses from recursive lookup.

           Takes a Zonemaster::Engine::Zone object ($zone).

           Returns an arrayref of Zonemaster::Engine::Nameserver objects, or `undef` if no parent
           zone was found.

       get_zone_ns_ips($zone)
           [External]

           This Method will obtain the IP addresses of the name servers, as extracted from the NS
           records of apex of the given zone.

           Takes a Zonemaster::Engine::Zone object ($zone).

           Returns an arrayref of strings, or `undef` if no parent zone was found.
