Subnetting Exercise Review

These flashcards cover key concepts and terminology related to subnetting, including address classes, subnet masks, and calculations for usable hosts and subnets.

Class C Address

An address in the range of 192 to 223 for IP addresses.

Default Subnet Mask

The default subnet mask for Class C addresses is 255.255.255.0.

Subnetting

The process of dividing a network into smaller logical sub-networks.

Usable Hosts

The number of IP addresses available for assignment to devices within a subnet, minus 2 for network and broadcast addresses.

Borrowed Bits

Bits taken from the host part of the IP address to create additional subnets.

Total Subnets Formula

2^N, where N is the number of bits borrowed to calculate the total number of possible subnets.

Custom Subnet Mask

A modified subnet mask to create subnets tailored to specific network requirements.

Usable Addresses Formula

2^H - 2, where H is the number of host bits, to calculate the number of usable IP addresses per subnet.

Broadcast Address

The last address in a subnet, used to communicate with all devices on that subnet.

Subnet Address

The first address in a subnet, representing the network itself, which cannot be assigned to hosts.
