[Key] grid.broadcast [Default] 10.10.255.255 [Description] 
The IP address mask that will define an Internet subnet. A Grid Server, when running, will broadcast its availability using UDP broadcasts. The mask determines which machines it will broadcast to. For example if all Grid Servers are on IP addresses 10.10.50.x, then a suitable mask will be 10.10.50.255. This will cause a message to be sent to every machine on the 10.10.50. network. If machines are distributed over a wider IP range, such as 10.10.50.x, 10.10.55.x, and 10.10.90.x, then a mask of 10.10.255.255 must be used to send to all 10.10.x.y addresses.
