FAQs on Class A in IP Addressing with Example Video Lecture - Computer Networks - Computer Science Engineering (CSE)
| 1. What is a Class A in IP Addressing? |  |
Ans. Class A in IP Addressing is a category of IP addresses that is designated for very large networks. The first bit in a Class A IP address is always 0, which allows for 126 networks and over 16 million hosts per network.
| 2. How is a Class A IP address structured? | |
Ans. A Class A IP address is structured as follows: The first octet represents the network portion, while the remaining three octets represent the host portion. The range of a Class A IP address is from 1.0.0.0 to 126.255.255.255.
| 3. What is the default subnet mask for a Class A IP address? | |
Ans. The default subnet mask for a Class A IP address is 255.0.0.0, which means that the first octet is used for the network portion, and the remaining three octets are used for the host portion.
| 4. How many total IP addresses are available in a Class A network? | |
Ans. In a Class A network, there are 16,777,214 total IP addresses available for hosts, as the first octet is dedicated to the network portion, leaving 24 bits for host addresses.
| 5. Can a Class A IP address be used for a small home network? | |
Ans. While technically a Class A IP address can be used for a small home network, it is not recommended due to the vast number of available host addresses (over 16 million) which would be excessive for a typical home network. It is more common to use Class C IP addresses for smaller networks.
