CIDR Subnet Mask & IP Range Calculator
Perform instant IPv4 subnetting. Calculate network IDs, broadcast addresses, usable host ranges, dotted decimal netmasks, and wildcard masks with bitwise binary clarity.
IP Address & CIDR Prefix
Subnet Architecture
Understanding Usable Hosts Formula (2^H - 2)
In any IPv4 subnet, the total host addresses equal 2^(32 - Prefix). However, two addresses are always reserved by protocol specification: the Network ID (all host bits 0, used by routing tables) and the Broadcast Address (all host bits 1, used to address all devices on the segment). Therefore, the formula for usable client IP assignments is strictly 2^H - 2.
