4.2.4 - Host Address Ranges

Flashcards about Host Address Ranges

What is the range of possible host IDs for the IP network 198.51.100.0/24?

254

In the IP network 198.51.100.0/24, how many bits long is the host ID portion?

8 bits

What is the host address range for a /24 network with the IP network 198.51.100.0?

198.51.100.1 to 198.51.100.254

In an IP address, what do the first three parts typically represent?

The network ID

In an IP address, what does the last part typically represent?

The host ID

For a /28 network, what parts of the IP address represent the network ID, subnet ID, and host ID?

The first three parts represent the network ID, the fourth part represents the subnet ID, and the fifth part represents the host ID.

What is the subnet mask for a /28 network described in the notes?

255.255.255.240

What is the purpose of subnetting?

To create layer 3 broadcast domain segments with fewer hosts.

What is the main consideration when designing subnets?

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

How does adding a bit to the subnet mask affect the number of available host addresses?

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