What is IP addressing? How IPv4 works| ipv4 vs ipv6 | 5 types of ip classes | public vs private ip
IT k Funde・16 minutes read
The video explains the basics of networking, focusing on IP addresses, binary numbers, IPv4, and IPv6, emphasizing the unique identifiers they provide for devices and the importance of subnetting. It highlights the distinction between public and private IP addresses and the need to transition to IPv6 due to the impending exhaustion of IPv4 addresses.
Insights
- IP addresses serve as unique identifiers for devices on a network, with a structure that includes decimal points and binary formats, classified into different classes (A, B, C) based on network and host divisions.
- The transition from IPv4 to IPv6 is crucial due to the limited capacity of IPv4 addresses compared to the vast number of unique IP addresses offered by IPv6, emphasizing the necessity for this shift as IPv4 addresses near depletion, highlighting the significance of subnetting for efficient network bandwidth management.

Recent questions
What are IP addresses and their purpose?
IP addresses are unique identifiers for devices on a network, allowing them to communicate with each other. They are essential for routing data packets to the correct destination and ensuring seamless connectivity within a network.
How are IP addresses classified?
IP addresses are classified into different classes (A, B, C) based on network and host divisions. Each class has a specific range of IP addresses allocated to it, determining the number of networks and hosts that can be accommodated within that class.
Why is subnetting important in networking?
Subnetting plays a crucial role in managing network bandwidth efficiently by dividing a large network into smaller subnetworks. This allows for better organization of network resources, improved security, and optimized data transmission within the network.
What is the difference between public and private IP addresses?
Public IP addresses are used for internet connectivity and device identification on a global scale, while private IP addresses are reserved for local networks and are not accessible from the internet. Private IPs provide exclusive communication within a local area network.
Why is transitioning to IPv6 necessary?
Transitioning to IPv6 is essential due to the limited capacity of IPv4 addresses, which are rapidly depleting. IPv6 offers a vast number of unique IP addresses, ensuring the continued growth of the internet and supporting the increasing number of connected devices worldwide.
