Every IPv4 prefix from slash 8 to slash 32 with its subnet mask and the number of usable hosts, plus the classful ranges and the reserved blocks. Slash 31 and slash 32 are named rather than counted because the two to the power n minus two rule does not apply to them. #networking #subnetting #ccna

📝Subnetting is the process of dividing a large IP network into smaller logical networks called subnets. In this unit, you will learn the fundamentals of subnetting, including network addresses, host addresses, broadcast addresses, subnet masks, CIDR notation, network bits, host bits, and borrowed bits. This unit also explains how subnetting works step by step using practical IPv4 examples such as /24, /25, /26, /27, /28, /29, and /30. You will learn important subnetting formulas, block size calculation, the difference between FLSM and VLSM, and how to efficiently allocate IP addresses according to network requirements.
🌐 IPv4 Bits Made Simple! Every IPv4 address is made up of 4 octets (8 bits each), and each octet represents a decimal value derived from its binary equivalent. Understanding how binary translates to decimal is the foundation of subnetting, IP addressing, routing, and network troubleshooting. 💡 Key takeaway: Mastering IPv4 bits makes it much easier to calculate subnets, identify network and host portions, and build a strong networking foundation for certifications like CCNA, CCNP, and beyond...
