IP Addressing Fundamentals Quiz! Trivia

1. There are ______ bits in an octet?

An octet is a unit of digital information that consists of 8 bits. Each bit can have a value of either 0 or 1, and when combined together, they form an octet. Therefore, the correct answer is 8, indicating that there are 8 bits in an octet.

2. Given the IP address 152.16.168.196/28, is the IP address 162.16.168.30 in the same network.

Yes

No

The given IP address 152.16.168.196/28 has a subnet mask of 28 bits, which means the first 28 bits represent the network address and the remaining 4 bits represent the host address. When we compare the network addresses of 152.16.168.196 and 162.16.168.30, we find that they are different. Therefore, the IP address 162.16.168.30 is not in the same network as 152.16.168.196.

Explanation

The given IP address 152.16.168.196/28 has a subnet mask of 28 bits, which means the first 28 bits represent the network address and the remaining 4 bits represent the host address. When we compare the network addresses of 152.16.168.196 and 162.16.168.30, we find that they are different. Therefore, the IP address 162.16.168.30 is not in the same network as 152.16.168.196.

3. What does /28 represent in the previous question?

The number of bits in the host portion of the IP address

The number of bits in the network portion of the IP address

The number of hosts in a network

The /28 represents the number of bits in the network portion of the IP address. In IP addressing, the network portion is used to identify the network to which the IP address belongs. The network portion is determined by the subnet mask, which is represented by the slash notation. In this case, /28 indicates that the first 28 bits of the IP address are used to identify the network, while the remaining bits are used for the host portion.

The /28 represents the number of bits in the network portion of the IP address. In IP addressing, the network portion is used to identify the network to which the IP address belongs. The network portion is determined by the subnet mask, which is represented by the slash notation. In this case, /28 indicates that the first 28 bits of the IP address are used to identify the network, while the remaining bits are used for the host portion.

4. What is the purpose of an IP Address?

A unique identifier for a computer

A unique location identifier

A network location identifier

Trick question, it is NOT a unique identifier.

Explanation

Trick question, it is NOT a unique identifier.

5. What is the name of the type of notation an IP address is usually written? ________ _________ notation.

The correct answer is "dotted quad notation". This is the most common way to represent an IP address, where the address is divided into four sections separated by periods, with each section represented by a decimal number.

6. What is the net ID for the network in which 192.168.242.5/20 is located?

The given IP address 192.168.242.5/20 has a subnet mask of 20 bits, which means the first 20 bits of the IP address represent the network ID. To determine the network ID, we need to consider the subnet mask and perform a bitwise AND operation with the IP address. In this case, when we perform the bitwise AND operation between 192.168.242.5 and the subnet mask 255.255.240.0 (converted from /20), we get the network ID 192.168.240.0. Therefore, the network in which the IP address 192.168.242.5/20 is located has a network ID of 192.168.240.0.

7. What is the broadcast address for the network in which 192.168.242.5/20 is located?

The given IP address 192.168.242.5/20 has a subnet mask of 20 bits, which means the first 20 bits of the IP address are network bits and the remaining 12 bits are host bits. In a /20 subnet, the network address can be calculated by setting all the host bits to 0. Therefore, the network address is 192.168.240.0. The broadcast address is obtained by setting all the host bits to 1, so the broadcast address for this network is 192.168.255.255.

Explanation

The given IP address 192.168.242.5/20 has a subnet mask of 20 bits, which means the first 20 bits of the IP address are network bits and the remaining 12 bits are host bits. In a /20 subnet, the network address can be calculated by setting all the host bits to 0. Therefore, the network address is 192.168.240.0. The broadcast address is obtained by setting all the host bits to 1, so the broadcast address for this network is 192.168.255.255.
