Common Subnets Quick Reference
Understanding IP Subnetting
Subnetting divides a network into smaller sub-networks, improving security and reducing network congestion. Each subnet has its own network address, broadcast address, and range of usable host addresses.
Key Concepts
Network Address: First address in the subnet, identifies the network itself
Broadcast Address: Last address, used to communicate with all hosts in subnet
Subnet Mask: Defines which portion of IP represents network vs host
