Networking 101: Part 3
- Networking requires understanding IP addressing, subnetting, and CIDR notation for efficient network design.
- IPv4 uses a 32-bit address format, while IPv6 uses a 128-bit address, offering a larger address space.
- IP addresses are divided into classes (A, B, C, D, E), each serving different network sizes and purposes.
- Public IPs are routable on the internet, while private IPs are used within private networks and cannot be routed.
- Subnetting involves breaking down large networks into smaller subnets for better management and resource allocation.
- CIDR notation simplifies network design by specifying the number of bits used for the network portion in an address.
- Subnetting examples demonstrate how to calculate usable hosts, network addresses, and broadcast addresses for different subnet sizes.
- VLSM allows for variable subnet sizes within a network, while Supernetting aggregates smaller subnets for simpler routing.
- Key takeaways include understanding IP addressing, subnetting, CIDR, VLSM, and Supernetting for efficient network management.
- To enhance skills, practice subnetting using online tools, design mock networks, and delve into binary conversion.
