Is there an existing module to query MS SQL Server Browser (ms-sql-m)?

Edit: The protocol (https://msdn.microsoft.com/en-us/library/cc219703.aspx) is simple. As I didn't find a module that provided easy access to it, I wrote my own query.

    if($self->{db_server} =~ m/(.*)\\(.*)/) {
        my $server = $1;
        my $instance = $2;
        # This is an instance name
        # Resolve instance name to a port number
        my $socket = new IO::Socket::INET(
            PeerAddr    => "$server:1434",
            Proto       => 'udp',
        );
        $socket->send("\x04$instance\x00");

        eval {
            local $SIG{ALRM} = sub { die "Timed out waiting for recv";
+ };
            alarm 20;    # wait up to 20 seconds for a response
            eval {
                my $ret = $socket->recv(my $data, 255);
                unless(defined($ret)) {
                    die "recv error: $!";
                }
                my ($srv_resp, $resp_data) = unpack("C n/a", $data);
                my $details = { split(/;/, $resp_data) };
                $self->{db_host} = $details->{ServerName};
                $self->{db_port} = $details->{tcp};
            };
            alarm 0;
            die $@ if($@);
        };
        alarm 0;
        if($@) {
            die "ERROR: Query SQL Server Browser failed with: $@";
        }
    }
