Subnetting Quiz: IP Address and Class B Subnets

A network protocol that utilizes a gateway to connect Internet of Things (IoT) nodes to the Internet.

A stack of protocols used to connect devices and systems within a network.

A standard abstract model that describes a stack of seven protocol layers, including the physical, data link, network, transport, session, presentation, and application layers.

A simplified version of the OSI model that combines some of the layers. It includes the application, transport, internet, and network interface layers.

A unique numerical identifier for each device on a network.

A process of directing data packets between devices on a network.

A network that connects devices within a limited geographical area, such as a building or campus.

A network that connects devices over a wider geographical area, spanning multiple locations or even countries.

A 32-bit number, similar to an IP address, that divides an IP address into network and host parts.

A subnet mask has a continuous string of 1s starting from the Most Significant Bit (MSB). The number of consecutive 1s indicates the network portion of the IP address.

The network part of an IP address identifies the network to which a device belongs. The host part identifies the specific device within the network.

The purpose of a subnet mask is to subdivide a network into smaller sub-networks, allowing for more efficient IP address allocation.

A subnet mask is called a 'subnet mask' because it defines sub-networks. It allows for logical partitioning of IP addresses beyond just the network part.

Class A IP addresses start with '0' in the first bit, followed by 7 network bits and 24 host bits.

Class B IP addresses start with '10' in the first two bits, followed by 14 network bits and 16 host bits.

Class C IP addresses start with '110' in the first three bits, followed by 21 network bits and 8 host bits.

The number of networks that can be created within a given IP address class. It is calculated using the formula 2^N, where N is the number of bits reserved for network addresses.

The total number of hosts (devices) that can be connected to a network. It is calculated using the formula 2^H, where H is the number of bits reserved for host addresses.

The number of usable hosts within a network, excluding the network and broadcast addresses. It is calculated by subtracting 2 from the total number of hosts.

The process of dividing a larger network into smaller, more manageable subnetworks. This is done by borrowing bits from the host portion of the IP address.

The number of subnetworks that can be created from a network. It is calculated using the formula 2^S, where S is the number of bits borrowed from the host portion for subnetting.

The starting address of a subnetwork. It is formed by combining the network portion of the original IP address with all zeros in the host portion.

The address that is used to broadcast a message to all devices within a subnetwork. It is formed by combining the network portion of the original IP address with all ones in the host portion.

The range of valid IP addresses that can be assigned to hosts within a subnetwork. It starts with the network address and ends with the broadcast address, excluding the network and broadcast addresses themselves.

The number of bits reserved for the network portion of the IP address determines the number of subnets that can be created within a network.

Subnet ranges define groups of IP addresses that share the same network portion, allowing for efficient allocation and management of IP addresses within a network.
