CIDR to IP Range Converter – Instant Subnet Calculator

Convert CIDR notation to IP address ranges with detailed network information

Input CIDR

CIDR Notation

Quick Examples

Enter a CIDR notation to see the IP range details

What is CIDR Notation?

CIDR (Classless Inter-Domain Routing) is a method for allocating IP addresses and routing Internet Protocol packets. The notation uses a slash followed by a number (e.g., /24) to indicate how many bits are used for the network portion of the address.

How to Convert CIDR to IP Range

Enter a CIDR block (like 192.168.1.0/24) above to instantly see the network address, broadcast address, usable IP range, subnet mask, and more.

Example Conversions

CIDR Block	IP Range	Usable Hosts
192.168.1.0/24	192.168.1.1 – 192.168.1.254	254
10.0.0.0/8	10.0.0.1 – 10.255.255.254	16,777,214
