      my $host = 'whois.radb.net';

      my $i = Net::IRR->connect( host => $host )

DESCRIPTION
    This module provides an object oriented perl interface to the Internet
    Route Registry. The interface uses the RIPE/RPSL Tool Query Language as
    defined in Appendix B of the IRRd User Guide. The guide can be found at
    http://www.irrd.net/, however an understanding of the query language is
    not required to use this module. Net::IRR supports IRRd's
    multiple-command mode. Multiple-command mode is good for intensive
    queries since only one TCP connection needs to be made for multiple
    queries. The interface also allows for additional queries that aren't
    supported by standard UNIX *whois* utitilies. Hopefully this module will
    stimulate development of new Route Registry tools written in Perl. An
    example of Route Registry tools can be found by googling for RAToolset
    which is now known as the IRRToolset. The RAToolset was originally
    developed by ISI, http://www.isi.edu/, and is now maintained by RIPE,
    http://www.ripe.net/.

METHODS
    connect - connect to a Route Registry server
            my $o = Net::IRR->connect(host=>$host, port=>$port)
                or die "can't connect to $host\n";

        This is the constructor used to create Net::IRR objects. The
        constructor returns an Net::IRR object upon a successful connection
        to the IRR server and undef upon failure.

    disconnect - closes the connection to the Route Registry server
            $o->disconnect;

    quit - same as disconnect().
            $o->quit;

    get_routes_by_origin - get routes with a specified origin AS
            my @routes = $o->get_routes_by_origin('AS5650');

        This method takes an autonomous system number and returns the set of
        routes it originates. Upon success this method returns a list of
        routes in list context or a string of space seperated routes. undef
        is returned upon failure.

    get_routes_by_community - get routes with a specified community
        This method is for RIPE-181 only. It is not supported by RPSL. This
        method takes a community object name and returns the set of routes
        it originates. Upon success this method returns a list of routes in
        list context or a string of space seperated routes. undef is
        returned upon failure.

    get_sync_info - view the mirror status of a database
            print $o->get_sync_info;

        This method provides database syncronization information. This makes
        it possible to view the mirror status of a database. This method
        optionally takes the name of a database such as RADB or ELI. If no
        argument is given the method will return information about all
        databases originating from and mirrored by the registry server. If
        the optional argument is given the database specified will be
        checked and it's status returned. This method returns undef if no
        database exists or if access is denied.

    get_as_set - get ASNs for a registered AS-SET object
            my @as = $o->get_as_set("AS-ELI", 1);

        This method takes an AS-SET object name and returns the ASNs found.
        The method takes and optional second argument which enables AS-SET
        key expasion since an AS-SET can contain both ASNs and AS-SET keys.
        undef is returned upon failure.

    match - get RPSL objects registered in the database
            print $o->match('aut-num', 'as5650');

        The example above will retrieve the aut-num object with the key
        as5650. This method will return after the first match. undef is
        returned upon failure.

    get_irrd_version - get the IRRd version number
            print $o->get_irrd_version;

        This methods takes no arguments and returns the version of the IRRd
        server that was specified as the hostname to the connect() method.

    route_search - perform route searches
            $o->route_search("208.186.0.0/15", EXACT_MATCH);

        This method takes two arguments, a route and an optional flag. The
        flag can be one of four values: EXACT_MATCH, LEVEL_ONE,
        LESS_SPECIFIC, MORE_SPECIFIC. These constants can be imported into
        your namespace by using the :all or :route export tag when importing
        the Net::IRR module.

            use Net::IRR qw( :route );

            print "EXACT_MATCH = " . EXACT_MATCH . "\n";

    sources - get or set the databases and the database search order used
    for queries.
        The default database is all and the default search order is the
        order they where defined in IRRd's configuration file. The sources()
        method accepts a list databases in the order you would like them
        searched in future queries. If no arguments are given the method
        will return a list of all the databases in the RR.

    update - add or delete a database object in the remote database
        This method takes three arguments. The first argument is the
        database to update. The second arguemnt is the action which can be
        either "ADD" or "DEL". The third and final required arguement is a
        route object in RPSL format.

    error - access error messages warn $o->error, "\n" if $o->error;
        Most Net::IRR methods set an error message when errors occur. These
        errors can only be accessed by using the error() method.
