Broadcast communication parameter [BCAST]

Specifies a broadcast address.

TCP/IP

String (in the form of an IP address)

Broadcasts to all addresses on the same subnet.

The default broadcast address is created using the local IP address and subnet mask. The subnet mask indicates which portion of the IP address identifies the network, and which part identifies the host.

For a subnet of 10.24.98.x, with a mask of 255.255.255.0, the default broadcast address is 10.24.98.255.

When specifying an IPv6 address on a Windows platform, use the interface identifier. UNIX platforms support both interface identifiers and interface names in IPv6 addresses. The interface identifier is required on Linux (kernel 2.6.13 and later).

To tell the client to broadcast only on interface number 2 when using IPv6, use:

LINKS=tcpip(BROADCAST=ff02::1%2)
