Calculadora de subred — Preguntas frecuentes
What is CIDR notation?
CIDR (Classless Inter-Domain Routing) notation uses an IP address followed by a slash and a number (e.g., 192.168.1.0/24) that indicates how many bits are used for the network prefix.
How do I calculate usable hosts?
Usable hosts = 2^(32-CIDR) - 2. The -2 accounts for the network address (first) and broadcast address (last), which cannot be assigned to hosts.
