We're working on a comprehensive educational guide for the IP Subnet Calculator in your language. The content below is shown in English.

Qué es IP Subnet Calculator?

▾

An IP subnet calculator breaks an IP address space into smaller networks. CIDR (Classless Inter-Domain Routing) notation specifies how many bits belong to the network portion — /24 means 24 bits for network, 8 bits for hosts, allowing 254 usable host addresses. Subnetting is essential for network design, router configuration, and firewall rules.

Calkulon makes complex calculations simple — built for students and everyday problem-solvers.

f(x)Subnet mask = n ones followed by (32−n) zeros in binary

Cómo IP Subnet Calculator

▾
  1. 1IP addresses are 32-bit numbers (IPv4), written as 4 octets: e.g. 192.168.1.0
  2. 2CIDR /n means first n bits are the network address
  3. 3Subnet mask = n ones followed by (32−n) zeros in binary
  4. 4Network address = IP AND subnet mask
  5. 5Broadcast address = network address OR NOT(subnet mask)
  6. 6Usable hosts = 2^(32−n) − 2 (subtract network and broadcast addresses)

Ejemplos resueltos

▾
Ejemplo 1
Dado:192.168.1.0/24
Resultado:Network: 192.168.1.0, Broadcast: 192.168.1.255, Hosts: 254

/24 gives 256 addresses, 254 usable

Ejemplo 2
Dado:10.0.0.0/8
Resultado:Network: 10.0.0.0, Hosts: 16,777,214

Class A private range — 16 million hosts
