54. What is IPv4? | Basics of IP Addressing Explained | Computer Networks

Welcome to the foundation of the Network Layer! In this Computer Networks tutorial, we dive deep into the Introduction to IPv4 (Internet Protocol Version 4). Before you can solve complex subnetting numericals, you must understand exactly how these 32-bit addresses are constructed, represented, and processed by routers.

Key Concepts Covered:

What is an IP Address and why do devices need it?

The 32-bit architecture of IPv4.

Dotted-Decimal Representation vs. Binary Representation.

The division of an IP Address: Network ID vs. Host ID.

Total number of possible IPv4 addresses (2^{32}).

If you are starting your preparation for GATE CS , UGC NET, or B.Tech Network Layer exams, this video will build the core concepts you need to master IP addressing!
