🔵 What is Subnetting?
Subnetting is the process of dividing a larger network into smaller, more manageable subnetworks (subnets).

🔵 What is Subnetting?
It is the process of dividing a large network into smaller, easier to manage subnetworks.

🔵 Why Subnetting is Important?
It improves network performance, enhances security, and helps in better IP address utilization.

🔵 Why is Subnetting important?
Because it improves network performance, increases security, and helps optimize IP addresses.

🔵 CIDR Notation & Subnet Mask:
Subnetting relies on CIDR notation (like /24, /26) and subnet masks (like 255.255.255.0).

🔵 CIDR encoding and network mask:
