NAME

       Net::DNS::Resolver::Recurse - Perform recursive dns lookups

SYNOPSIS

         use Net::DNS::Resolver::Recurse;
         my $res = Net::DNS::Resolver::Recurse->new;

DESCRIPTION

       This module is a sub class of Net::DNS::Resolver. So the methods for Net::DNS::Resolver
       still work for this module as well.  There are just a couple methods added:

   hints
       Initialize the hint servers.  Recursive queries need a starting name server to work off
       of. This method takes a list of IP addresses to use as the starting servers.  These name
       servers should be authoritative for the root (.) zone.

         $res->hints(@ips);

       If no hints are passed, the default nameserver is asked for the hints.  Normally these IPs
       can be obtained from the following location:

         ftp://ftp.internic.net/domain/named.root

   recursion_callback
       This method is takes a code reference, which is then invoked each time a packet is
       received during the recursive lookup.  For example to emulate dig's "+trace" function:

        $res->recursion_callback(sub {
            my $packet = shift;

            $_->print for $packet->additional;

            printf(";; Received %d bytes from %s\n\n",
                $packet->answersize,
                $packet->answerfrom
            );
        });

   query_dorecursion
       This method is much like the normal query() method except it disables the recurse flag in
       the packet and explicitly performs the recursion.

         $packet = $res->query_dorecursion( "www.netscape.com.", "A");

IPv6 transport

       If the appropriate IPv6 libraries are installed the recursive resolver will randomly
       choose between IPv6 and IPv4 addresses of the nameservers it encounters during recursion.

       If you want to force IPv4 transport use the force_v4() method. Also see the IPv6 transport
       notes in the Net::DNS::Resolver documentation.
