NAME

       Zonemaster::DNSName - class representing DNS names

SYNOPSIS

           my $name1 = Zonemaster::Name->new('www.example.org');
           my $name2 = Zonemaster::Name->new('ns.example.org');
           say "Yay!" if $name1->common($name2) == 2;

ATTRIBUTES

       labels
           A reference to a list of strings, being the labels the DNS name is made up from.

METHODS

       new($input) _or_ new({ labels => \@labellist})
           The  constructor  can be called with either a single argument or with a reference to a hash as in the
           example above.

           If there is a single argument, it must be either a non-reference, a Zonemaster::DNSName object  or  a
           Zonemaster::Zone object.

           If  it's  a non-reference, it will be split at period characters (possibly after stringification) and
           the resulting list used as the name's labels.

           If it's a Zonemaster::DNSName object it will simply be returned.

           If it's a Zonemaster::Zone object, the value of its "name" attribute will be returned.

       string()
           Returns a string representation of the name. The string representation  is  created  by  joining  the
           labels with dots. If there are no labels, a single dot is returned. The names created this way do not
           have a trailing dot.

           The stringification operator is overloaded to this function, so it should rarely be necessary to call
           it directly.

       fqdn()
           Returns the name as a string complete with a trailing dot.

       str_cmp($other)
           Overloads string comparison. Comparison is made after converting the names to upper case, and ignores
           any trailing dot on the other name.

       next_higher()
           Returns  a  new Zonemaster::DNSName object, representing the name of the called one with the leftmost
           label removed.

       common($other)
           Returns the number of labels from the rightmost going left that are the same in both names.  Used  by
           the recursor to check for redirections going up the DNS tree.

       prepend($label)
           Returns a new Zonemaster::DNSName object, representing the called one with the given label prepended.

       TO_JSON
           Helper method for JSON encoding.
