BCASTADDR Functionality Not Included in Windows NT

MORE INFORMATION

In LAN Manager and Windows for Workgroups, this TCP/IP parameter forces the IP address used to broadcast name requests. It allows an address of 255.255.255.255 or 0.0.0.0 to be used for this purpose.

The following Windows NT Registry entry affects the broadcast address, but only the last two octets:

   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\<adapter name#>
      \parameters \tcpip

   BroadcastType    REG_DWORD
      This value can be 0 or 1  (1 by default)
				

Assume a workstation has a TCP/IP address of 130.24.48.140 and a subnet mask of 255.255.0.0. The workstation address is ANDed with the subnet mask to find the first two octets of 130.24. When BroadcastType is set to 1, the broadcast address becomes 130.24.255.255. When BroadcastType is set to 0, the broadcast address becomes 130.24.0.0.
