10.56.176.0 is your network. 255.255.240.0 is your subnet mask. Valid broadcast addresses would be 10.56.176.255 (network broadcast) and 255.255.255.255 (general network broadcast). The general network broadcast would actually broadcast to every machine on the internet, but internet routers will block all traffic from it to prevent this. In effect if you use either 10.56.176.255 or 255.255.255.255, the result is broadcasting to all machines on your network.
Generally speaking, routers will unicast-forward incoming packets which have a network broadcast address as destination, unless they are directly connected to that network/subnet and therefore know that the destination address is a broadcast address
Local loopback address
local network broadcast
The general rule in networking is that the network id cannot be all zeroes or all ones, and the host id cannot be all zeroes or all ones. The all zero address results in a reserved address meaning "this network". The all ones address is a broadcast address, and cannot be assigned to a single system.
The company decides what addresses to use for the local network; the reserved address ranges, recommended for private networks, are:Class A: 10.0.0.0 - 10.255.255.255Class B: 172.16.0.0 - 172.31.255.255Class C: 192.168.0.0 - 192.168.255.255
All devices on your network segment. This is the 255.255.255.255 address which is reserved for broadcast transmissions. pg 147
The address before the next valid network address will be the broadcast address For Example:192.168.1.64 the broadcast address is 192.168.1.127
The broadcast address on IPv4 networks is the subnet address, padded on the right with ones. For example, if the subnet address is 192.168.x.y, with a subnet mask of 255.255.0.0, then the broadcast address is 192.168.255.255.
