4.2.4 - Host Address Ranges and Subnetting

A set of vocabulary flashcards summarizing key concepts related to host address ranges and subnetting.

IP Network 198.51.100.0/24

Allows for 254 possible host IDs, with host ID portion being 8 bits long.

Host Address Range for /24 Network

Ranges from 198.51.100.1 to 198.51.100.254, with subnet mask of 255.255.255.0.

Subnetting

The process of creating layer 3 broadcast domain segments with fewer hosts.

Host Address Range for /28 Network

Examples include 198.51.100.0, 1 to 14; 198.51.100.16, 17 to 30; and so forth.

Subnet Mask

Defines the division between the network ID and host ID.

Subnet Design Consideration

To fit the scheme to the requirements for the number of subnetworks and hosts per subnet.

Effect of Adding Bits to the Subnet Mask

Each bit added approximately halves the number of available host addresses.
