IP Subnet Calculation and Network Understanding

Subnet Mask Key Summary

  • Subnet Mask: The bitmask that separates the Network ID from the Host ID.
  • CIDR: Classless Inter-Domain Routing, represented by the number of network bits (e.g., /24).
  • Broadcast: The address used to send a packet to every device on that specific network.
