hari ke 4...best tp x best sgt coz x de pc sndr...kene share..nak wat pape pun x leh..huhu...x pe..sbr...~ nie note care nak kire bil.subnet n bil.host..

formula

x = bil.bit 1
2 ^ x = bil subnet
y = bil.bit 0
2 ^ y = bil.host

cth pengiraan :

192.168.0.0 /26 ---> 255.255.255.192
192 = 1100 0000

bil.subnet = 2 ^x
= 2 ^2
= 4

bil.host = 2 ^ y
= 2 ^6
= 64
