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 |
