About IPv4 Addressing & Subnets
Understand how IPv4 subnets, CIDR notation, and network scopes operate.
An IPv4 address is a 32-bit numerical identifier assigned to devices on a network. Classless Inter-Domain Routing (CIDR) notation allows network administrators to allocate subnets flexibly by specifying the exact bit length of the network prefix.
This tool computes complete subnet properties including network boundaries, broadcast addresses, usable host capacity, and binary representation instantly in your browser.
CIDR Subnet Calculations
Select any prefix from /0 to /32 to calculate network boundaries and subnet masks.
Usable Host Ranges
Determine the exact first and last usable host IPs while excluding network and broadcast addresses.
32-Bit Binary Breakdown
Converts every octet into 8-bit binary strings for precise bitwise network analysis.
Hex & Decimal Formats
Instantly computes 32-bit unsigned integers and hexadecimal network representations.
Public & Private Classification
Identifies RFC 1918 private blocks, loopback interfaces, link-local addresses, and public IP scopes.
