Key Concepts

Default Subnet Masks in Classful Addressing

In classful addressing, each IP address class has an associated default subnet mask. This default mask determines how many bits are used for the network portion as opposed to the host portion of the address. For example, Class B addresses have a default subnet mask of 255.255.0.0, meaning the first two octets represent the network and the last two represent the host.

IP Address Classes

IP address classes are a method of categorizing the address space in IPv4 networks, where addresses are divided into different classes (A, B, C, D, E) based on the range of their first octet. Each class has a default division between the network and host portions of the address. For instance, Class B addresses, which typically range from 128 to 191 in the first octet, have a default subnet mask that allocates the first two octets for the network and the remaining two for hosts.

Subnet Masks

A subnet mask is a 32-bit number that separates an IP address into the network and host parts. It works by masking the IP address, allowing systems to determine which portion of the address refers to the network and which refers to the individual host. Subnet masks are crucial in routing data in IP networks as they define network boundaries.
