how to connect the velodyne HDL-64 to ROS-indigo?

edit

This is ip addresses infromation of HDL-64E_S3.

 ROS version: indigo
 Laser Moudle: velodyne HDL-64E_S3

I follow the tutorial to set the IP address information.

[link text ( http://wiki.ros.org/velodyne/Tutorial... )

$sudo apt-get install ros-indigo-velodyne

$sudo ifconfig eth0 192.168.3.43

$sudo route add 192.168.XX.YY eth0
I don't know how to define the XX and YY. I don't have the CD which have this information. Below this picture is my use wireshark interface.
