IP Address Quiz

What is an IP address used for in an IP network?

• To uniquely identify a device

• To determine the physical location of a device

• To store data on a device

• To encrypt data sent from a device

Answer explanation

An IP address is used in an IP network to uniquely identify a device, allowing data packets to be routed to the correct destination.

How many bits is an IPv4 address made up of?

• 16-bit

• 32-bit

• 64-bit

• 128-bit

Answer explanation

An IPv4 address is made up of 32 bits, as each of the four octets in the address consists of 8 bits, totaling 32 bits for the entire address.

How many different classes does IPv4 have?

• 3

• 4

• 5

• 6

Answer explanation

IPv4 has 5 different classes: A, B, C, D, and E. Each class has a different range of IP addresses. Therefore, the correct answer is 5.

Which classes of IP addresses are considered standard Internet and intranet routable addresses?

• Class A, B, and C

• Class B, C, and D

• Class C, D, and E

• Class D and E

Answer explanation

The standard Internet and intranet routable addresses are Class A, B, and C. These classes provide a range of IP addresses suitable for networking purposes.

Which class of IP addresses is used only for intranet and is not routable on the Internet?

• Class A

• Class B

• Class C

• Class E

Answer explanation

Class C IP addresses are used only for intranet and are not routable on the Internet, making them suitable for private networks.

What is the purpose of Class D IP addresses?

• Standard Internet routing

• Intranet routing

• Multicast addresses

• Research purposes

Answer explanation

Class D IP addresses are used for multicast addresses, allowing multiple devices to receive the same data stream simultaneously.

Which class of IP addresses is used for research?

• Class A

• Class B

• Class D

• Class E

Answer explanation

Class E IP addresses are reserved for research purposes, as specified by the Internet Engineering Task Force (IETF).

What is the purpose of IP addresses according to the material provided?

• To identify the physical location of a computer

• To encrypt data packets for secure transmission

• To route packets to destinations

• To store data in a cloud network

Answer explanation

IP addresses are used to route packets to their destinations, allowing for proper communication between devices on a network.

Which IP address class has a range of first octet from 1 to 126?

• Class A

• Class B

• Class C

• Class D

Answer explanation

The IP address class with a range of first octet from 1 to 126 is Class A. Class A addresses have a first octet range of 1 to 126, making it the correct choice.

How many network bits are there in a Class C IP address?

• 8

• 16

• 24

• 32

Answer explanation

In a Class C IP address, there are 24 network bits. This is because Class C addresses use the first 3 octets for the network portion, leaving 1 octet (8 bits) for host addresses.
