Calculate network details from any IPv4 CIDR notation
| CIDR | Subnet Mask | Wildcard | Hosts | Class |
|---|
A subnet (subnetwork) is a logical division of an IP network. Subnetting allows network administrators to divide a network into smaller, more manageable segments.
CIDR (Classless Inter-Domain Routing) notation represents an IP address and its network prefix. For example, 192.168.1.0/24 means the first 24 bits are the network portion.
The number of usable hosts = 2^(32 - prefix) - 2. We subtract 2 because one address is reserved for the network address and one for the broadcast address.
