When you set up a sub network you decide upon the subnet mask and this determines the network address (all zeros in the subnet portion of the address) and the broadcast address (all ones in the subnet portion of the address). When you assign the host addresses in your subnet, then you use the addresses between the network address and the broadcast address.
255.255.255.0 is the subnet mask that provides 256 addresses of which the first (0) and last (255), the broadcast addresses are excluded, leaving 254 usable addresses.
255.255.255.224 will select a network of 32 IP addresses, with the lowest reserved as the network identifier, and the highest as the broadcast address, leaving 30 usable host IP addresses.
This could be a couple of things, but you are likely referring to TCP/IP protocol broadcasts. A broadcast address is when a data packet is sent to a special address to which all nodes on the network are supposed to accept and optionally respond to. While a broadcast address is defined for the entire network, this is not implemented in practice. For an IP subnet, the last address in the subnet's address space is the broadcast. For example, if my subnet is defined as 192.168.1.0/24 (very common for consumer network hardware including Wi-Fi), this defines the following: the network itself is identified as 192.168.1.0, the subnet mask is 255.255.255.0 (24 binary 1s in a row), the usable host addresses are 192.168.1.1 through 192.168.1.254, and the broadcast address is 192.168.1.255.
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.
The first and last IP address on each network. e.g. In a classful class C network, the IP addresses x.x.x.0 and x.x.x.255 are invalid and cannot be assigned to a network interface card. x.x.x.0 is the network address for the subnet. x.x.x.255 is the network broadcast address for the subnet.
That depends on the subnet's subnet mask.
There are 4094 usable IP addresses in a 20-bit subnet.
Computers have a unique IP address to identify them, just like in the real world having 2 equal addresses causes confusion.They don't have their own subnet though, they are part of a subnet which consists of at least 2 pc's. Subnets each have their own broadcast address and default gateway, as well as a limited amount of IP-addresses (determined by the subnet mask) to prevent abuse and to ease scaling.
253. Valid addresses would be from 10.20.50.1 to 10.20.50.254 10.20.50.0 is the network address. 10.20.50.255 is the network broadcast address. Any network with a subnet mask of 255.255.255.0 will support 253 hosts.
In a 24 bit subnet (subnet mask = 255.255.255.0), the address 192.1.6.255 is the broadcast address for the subnet 192.1.6.0/24.
The correct term is subnet mask instead of subnet mass. A subnet mask separates an IP address into the host address and the network address. It is a 32-bit number that can mask an IP address.
