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.
