About Subnetting
- • CIDR (Classless Inter-Domain Routing) notation specifies the network portion of an IP
- • /24 means 24 bits for network, 8 bits for hosts (256 addresses, 254 usable)
- • Network address is the first address, broadcast is the last
- • Usable hosts exclude network and broadcast addresses (except /31 and /32)
IP Subnetting - التفاصيل التقنية
Subnetting divides IP networks into smaller segments. CIDR notation (e.g., /24) indicates how many bits are used for the network portion. Understanding subnets is essential for network design and security.
