These addresses are not assigned to devices because they have a reserved meaning. All zeroes refers to "this network", and all ones usually is assigned to a broadcast address (all devices).
Usually, in dynamic addressing models, the host obtains its IP address via DHCP - an administrator sets up a pool of available addresses in an IP range (called a scope) and gives them to clients as they ask for addresses.
That means that the DHCP server keeps track of what IP addresses - out of a pool (or set) of addresses - have been assigned. Any time a host (computer or similar) requests an IP address, the DHCP server will assign an available address and mark it, in its memory, as "assigned" so it won't assign the same address to another computer.That means that the DHCP server keeps track of what IP addresses - out of a pool (or set) of addresses - have been assigned.

2046 Breakdown: 11111111.11111111.11111000.00000000 /21 - 21 bits in network address represented by ones in binary address above. Leaves 2^11th power host addresses left (the zeros to the right). Equals 2048 host addresses minus the two reserved addresses = 2046

Because they need a device to communicate with a distant network through. These devices are called gateways, and are normally routers. The hosts on a segment need to have knowledge of the gateway device in order to communicate outside the segment. In most environments, the local network will have an internal addressing scheme, one that is not routable on the internet, so there needs to be a device that can translate the internal addresses (non routable on the internet) into external addresses (routable on the internet). Of course this device needs to be connected to both the internal network and the external network to be able to send traffic between them.
That leaves us 5 bits for the host (32 - 27 = 5); the size of the network is 25 = 32 IP addresses, that is, addresses 10.150.100.96 - 10.150.100.127. The first and last address are not usable (can't be assigned to hosts), which leaves us with addresses 10.150.100.97 - 10.150.100.126.That leaves us 5 bits for the host (32 - 27 = 5); the size of the network is 25 = 32 IP addresses, that is, addresses 10.150.100.96 - 10.150.100.127.

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.
Usually the highest address in any given subnet (all 1's in binary) is that networks broadcast address and the lowest address in that same subnet (all 0's in binary) is that networks net-ip (in other words, the address of "the network"). These two addresses are typically never assigned to a host.
One - by your problem statement, all addresses are part of the same network. The number of host addresses is 232-21 - 2, or about 2000.One - by your problem statement, all addresses are part of the same network.

The IP protocol identifies both the logical host as well as the logical network addresses...........
Most usually the Dynamic Host Configuration Protocol that is set on a router, but sometimes the network administrator manually gives the ip addresses to each host.
