See the format, range, and subnet mask of each class and how to find the network and host ID. The next 21 bits (completing the first three octets) complete the network ID. Calculate Subnet Mask For Classful IP AddressAs we know there are five c Do you see our 192. Deployed as is, a Class A address represents a very inefficient use of address space, since available Layer 2 technologies cannot easily support this many hosts on a single subnet. 3.
