IPv4 Address Categories, CCNA 1 v7 Modules 11–13 Exam, and the Role of Dumpsarena in Certification Preparation

The world of networking is built on the foundation of IP addressing, and IPv4 (Internet Protocol version 4) remains one of the most widely used protocols despite the emergence of IPv6. Understanding IPv4 addressing is crucial for anyone pursuing a career in networking, especially for those preparing for the Cisco Certified Network Associate (CCNA) certification. This article delves into the intricacies of IPv4 address categories, explores the CCNA 1 v7 Modules 11–13 exam, and highlights how resources like Dumpsarena can aid in certification preparation.

Understanding IPv4 Address Categories

IPv4 addresses are 32-bit numerical identifiers assigned to devices in a network. These addresses are divided into five classes: A, B, C, D, and E. Each class has a specific range and purpose, making it essential for network administrators to understand their differences.
