Calculate network details from CIDR notation (IPv4)
| Network address | 192.168.1.0/24 | |
| Subnet mask | 255.255.255.0 | |
| Broadcast address | 192.168.1.255 | |
| Host range | 192.168.1.1 〜 192.168.1.254 | |
| Usable hosts | 254 | |
| Wildcard mask | 0.0.0.255 |
/24 = 254 hosts (typical home/small LAN), /16 = 65,534 hosts, /30 = 2 hosts (router links), /32 = a single host. Per RFC 3021, /31 allows both addresses to be used on point-to-point links.
