EXPORTED FUNCTIONS

       info($tag, $href)
           Creates  and  returns  a  Zonemaster::Engine::Logger::Entry  object.  The object is also added to the
           global logger object's list of entries.

       ns($name, $address)
           Creates and returns a nameserver object with the given name and address.

       name($string_name_or_zone)
           Creates and returns a Zonemaster::Engine::DNSName object for the given argument.

       zone($name)
           Returns a Zonemaster::Engine::Zone object for the given name.

       parse_hints($string)
           Parses   a   string   in    the    root    hints    format    into    the    format    expected    by
           Zonemaster::Engine::Resolver->add_fake_addresses().

           Returns a hashref with domain names as keys and arrayrefs to IP addresses as values.

           Throws an exception if the inputs is not valid root hints text.

           A  root  hints  file is a valid RFC 1035 zone file of the same type IANA publishes to be used as hint
           file for name servers <https://www.internic.net/domain/named.root>.

           In addition to being valid zone file the following restrictions are imposed on the root hints format:

           •   The file must not contain any $TTL, $ORIGIN, $INCLUDE or $GENERATE directives.

           •   The class field of all records must be "IN" or absent. If class is absent, IN is assumed.

           •   The TTL field may be absent or present. The TTL value is ignored.

           •   The RR type of all DNS records must be NS, A or AAAA.

           •   The file must contain at least one NS record.

           •   The owner name of all NS records must be ".".

           •   For every NS record there must be at least one address record (A or AAAA)  whose  owner  name  is
               identical to the domain name in the RDATA of the NS record.

           •   All  address  records (A or AAAA) must have an owner name that is identical to the domain name in
               the RDATA of some NS record in the zone.

       serial_gt($serial_a, $serial_b) Checks if serial_a is greater than serial_b, according to serial number
       arithmetic as defined in RFC1982, section 3.2.
           Return a boolean.

       scramble_case
           This routine provides a special effect: sCraMBliNg tHe CaSe

       should_run_test
           Check if a test is blacklisted and should run or not.

       ipversion_ok
           Check    if    IP    version    operations    are    permitted.    Tests     are     done     against
           Zonemaster::Engine::Profile->effective content.
