linux only :

contoh : 10.10.50.215/24(subnet 255.255.255.0)
berapa network, broadcast dan ip yang valid?

caranya :
ketik : ipcalc 10.10.50.215/24 lalu enter :
hasilnya :

Address: 10.10.50.215
Netmask: 255.255.255.0 = 24
Wildcard: 0.0.0.255
=>
Network: 10.10.50.0/24
HostMin: 10.10.50.1
HostMax: 10.10.50.254
Broadcast: 10.10.50.255
Hosts/Net: 254

semoga berguna 🙂
