Subneter provides a basic deconstruction of CIDR Notation on IPv4 address for your subnetting needs.
Enter valid CIDR notation such as 192.168.1.1/18 and, if the table doesn't automatically update, click Run.
The table will be populated with the following information:
- Class
- Subnet Mask
- Network ID
- Broadcast IP
- Hosts
The number of hosts displayed is the total number of addresses in your range minus 2 reserved addresses: Network ID (first address), and Broadcast (last address).
Happy subnetting.
