Subnetting: Rumus Menghitung Banyak Subnet

This document discusses subnetting and CIDR notation. It provides formulas for calculating the number of subnets and hosts per subnet based on the subnet mask. Tables are included that show CIDR values, shortcut values for subnetting, and a quick table for determining subnets and hosts. Formulas are also provided for calculating the subnet block and performing subnetting calculations using binary and power of two values.

SUBNETTING  Rumus Menghitung Banyak Subnet

Subnet = 2x
 Tabel CIDR (Classless Inter-Domain Routing) x = jumlah binary 1 pada octet terakhir subnet mask

Subnet Mask Nilai CIDR

 Rumus Menghitung Jumlah Host per
255.192.0.0 /10 Subnet
255.224.0.0 /11 Host per Subnet = 2y – 2
255.240.0.0 /12 y = jumlah binary – pada octet terakhir subnet mask
255.248.0.0 /13
255.252.0.0 /14  Rumus Menghitung Blok Subnet
255.254.0.0 /15 Blok Subnet = 256 – Z
255.255.0.0 /16 z = nilai octet terakhir subnet mask
