aku ada soalan ni hehe..

IP : 172.16.0.0

Class : class B

segment : 490

host per segment :

2^7-2=126

subnet mask :

2^7=128

255.255.255.128

as ape aku blaja kena buat table

| subnet | host | range | broadcast |

camne korang kira utk table kat atas ni ? aku konpius dgn IP dia tu..

nak cuba try test eh..kalu salah kang mintak tolong betulkan..

IP : 172.16.0.0

subnet mask :

255.255.255.128

subnet mask dlm bentuk decimal :

11111111.11111111.11111111.10000000

11111111 = 128 + 64 + 32 + 16 + 8 + 4 + 2 + 1 = 255

oleh itu, 1 pada oktet ke 4 yang makcik boldkan tu bernilai 128. maknanya, host range bagi setiap subnet adalah 128

valid host per subnet / segment :

128-2=126 (sebab tolak Network ID dan Broadcast ID)

bila saya letak dlm bentuk jadual, ia akan jadi begini :
