Net-CIDR-Overlap

A utility module for helping make sure a list of CIDRs don't overlap.

    my $nco=Net::CIDR::Overlap->new;
    
    # add some subnets
    eval{
        $nco->add( '127.0.0.0/24' );
        $nco->add( '192.168.42.0/24' );
        $nco->add( '10.10.0.0/16' );
    }
    if ( $@ ){
        warn( $@ );
    }
    
    # this will fail as they have already been added
    eval{
        $nco->add( '127.0.0.0/25' );
        $nco->add( '10.10.10/24' );
    }
    if ( $@ ){
        warn( $@ );
    }
    
    # this will fail this is not a valid CIDR
    eval{
        $nco->add( 'foo' );
    }
    if ( $@ ){
        warn( $@ );
    }
    
    # print the subnets we added with out issue
    my $list=$nco->list;
    foreach my $cidr ( @${ $list } ){
        print $cidr."\n";
    }
