Chapter 3 - IP Addressing

Question 1

IPv4

Answer 1

Each host needs a subnet mask

Subnet distinguishes the network identifier from the host identifier.

Question 2

CIDR

Answer 2

Classless Inter Domain Routing

Indicates how many once in an address

11111111.11111111.00000000.00000000

/16

Question 3

Classless IPv4

Answer 3

Easily distributes addresses.

Is a network that uses subnetting.

Submitting breaks network into smaller units.

Class is defined by the number in the first Octet and default subnet mask.

The more bits used to identify hosts the larger a network can be.

Question 4

Class A Default Subnet Mask

Answer 4

255. 0.0.0
256. 00000000.00000000.0000000

1st 8bits identify the network
24bits identify the host

Large networks

Question 5

Class B Default Subnet Mask

Answer 5

255. 255.0.0
256. 11111111.00000000.00000000

16bits for the networks
16bits for the host

Medium sized networks

Question 6

Class C Default Subnet Mask

Answer 6

255. 255.255.0
256. 11111111.11111111.00000000

24bits for network
8bits for host

Small networks

Question 7

Supernetting

Answer 7

Condense multiple subnets into a larger network.

Increases the number of host addresses to make the network larger
