How to Use

Enter any valid IPv4 address and select a CIDR prefix. The calculator instantly shows the binary, decimal, and hexadecimal representations, classifies the IP class (A-E), identifies whether it is private or public, and displays the CIDR block.

Example Calculation

For IP 192.168.1.1 with /24: Binary = 11000000.10101000.00000001.00000001, Decimal = 3,232,235,777, Hex = C0A80101, Class C, Private Address, CIDR Block = 192.168.1.0/24.

Formula

Binary: each octet → 8-bit binary\nDecimal: (O1 × 2²⁴) + (O2 × 2¹⁶) + (O3 × 2⁸) + O4\nHexadecimal: each octet → 2-digit hex\n\nClass A: 1.0.0.0 − 127.255.255.255\nClass B: 128.0.0.0 − 191.255.255.255\nClass C: 192.0.0.0 − 223.255.255.255\nClass D: 224.0.0.0 − 239.255.255.255 (Multicast)\nClass E: 240.0.0.0 − 255.255.255.255 (Reserved)\n\nPrivate Ranges: 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16

Frequently Asked Questions

Common questions and answers about the IP Address Calculator.

The IP Address Calculator is a free online tool designed to analyze any ipv4 address to reveal its binary, decimal, hex, class, address type (public/private), and cidr block. It allows you to perform these calculations quickly and accurately without manual computations.
Enter any valid IPv4 address and select a CIDR prefix. The calculator instantly shows the binary, decimal, and hexadecimal representations, classifies the IP class (A-E), identifies whether it is private or public, and displays the CIDR block. Once you enter these values, the calculator will automatically compute and display the results instantly.
The IP Address Calculator uses the following formula to calculate your results: Binary: each octet → 8-bit binary\nDecimal: (O1 × 2²⁴) + (O2 × 2¹⁶) + (O3 × 2⁸) + O4\nHexadecimal: each octet → 2-digit hex\n\nClass A: 1.0.0.0 − 127.255.255.255\nClass B: 128.0.0.0 − 191.255.255.255\nClass C: 192.0.0.0 − 223.255.255.255\nClass D: 224.0.0.0 − 239.255.255.255 (Multicast)\nClass E: 240.0.0.0 − 255.255.255.255 (Reserved)\n\nPrivate Ranges: 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16 This formula is standard and widely accepted for these types of calculations.
Sure! Here is a practical example: For IP 192.168.1.1 with /24: Binary = 11000000.10101000.00000001.00000001, Decimal = 3,232,235,777, Hex = C0A80101, Class C, Private Address, CIDR Block = 192.168.1.0/24. This example demonstrates how the inputs are processed through the formula to yield the final results.
