◆ GetSubnetDirectedBroadcast()

Ipv4Address ns3::Ipv4Address::GetSubnetDirectedBroadcast ( const Ipv4Mask mask) const

Generate subnet-directed broadcast address corresponding to mask.

The subnet-directed broadcast address has the host bits set to all ones. If this method is called with a mask of 255.255.255.255, (i.e., the address is a /32 address), the program will assert, since there is no subnet associated with a /32 address.

Parameters
maska network mask
Returns
a broadcast address for the subnet.
