![]() Each subnet can have a flexible host count and a limited number of IP addresses. ![]() A subnet mask is a set of identifiers that returns the network address’s value from the IP address by turning the host address into zeroes.Ī VLSM sequence allows network administrators to break down an IP address space into subnets of various sizes. Classless addressesĬlassless or Classless Inter-Domain Routing (CIDR) addresses use variable length subnet masking (VLSM) to alter the ratio between the network and host address bits in an IP address. For instance, consider 192.168.1.100, where 192.168.1 is the network address and 100 is the host address. Class CĪ Class C IPv4 address has 24 network prefix bits. For example, consider 128.16.0.2, where 128.16 is the network address and 0.2 is the host address. Class BĪ Class B IPv4 address has 16 network prefix bits. For example, consider 44.0.0.1, where 44 is the network address and 0.0.1 is the host address. Class AĪ Class A IPv4 address has 8 network prefix bits. Organizations could purchase three classes of IPv4 addresses. Each string of numbers separated by the period consists of 8 bits, represented by 0 to 255 in numerical forms. Classful addressesĪn IPv4 address consists of 32 bits. The total length of the address was fixed, and the number of bits allocated to the network and host portions were also fixed. Until the early 1990s, IP addresses were allocated using the classful addressing system. The host address is a series of numbers indicating the host or individual device identifier on the network.The network address is a series of numerical digits pointing to the network's unique identifier.
