bionic (3) Zonemaster::Recursor.3pm.gz

NAME

       Zonemaster::Recursor - recursive resolver for Zonemaster

SYNOPSIS

           my $packet = Zonemaster::Recursor->recurse($name, $type, $class);
           my $pname = Zonemaster::Recursor->parent('example.org');

METHODS

       recurse($name, $type, $class)
           Does a recursive resolution from the root servers down for the given triplet.

       parent($name)
           Does a recursive resolution from the root down for the given name (using type "SOA" and class "IN").
           If the resolution is successful, it returns the domain name of the second-to-last step. If the
           resolution is unsuccessful, it returns the domain name of the last step.

       get_ns_from($packet, $state)
           Internal method. Takes a packet and a recursion state and returns a list of ns objects. Used to
           follow redirections.

       get_addresses_for($name[, $state])
           Takes a name and returns a (possibly empty) list of IP addresses for that name (in the form of
           Zonemaster::Net::IP objects). When used internally by the recursor it's passed a recursion state as
           its second argument.

       clear_cache()
           Class method to empty the cache of responses to recursive queries.

       root_servers()
           Returns a list of ns objects representing the root servers. The list of root servers is hardcoded
           into this module.
