14. Network Prefixes
Simbol : “/”
Contoh : 172.16.4.0
/ 28  28 bits
pertama adalah
NETWORK ADDRESS
“Prefix Length”
Jumlah bits
yang
merepresentasi
kan NETWORK
portion
Sisa bits  HOST
ADDRESS
Sisa bits  HOST
ADDRESS
Contoh : 172.16.4.0
/24  24 bits
pertama adalah
NETWORK
ADDRESS

/31 2

16. Subnet Mask
Cara lain
menentukan
NETWORK ADDRESS
Dotted decimal , 32
bits
Korelasi dengan
IPv4
 nilai 1 di
NETWORK ADDRESS
 nilai 0 di HOST
ADDRESS

17. Subnet Mask
Contoh : /24 = 24 bits pertama adalah network address, 8
bits adalah host
 11111111.11111111.11111111.00000000
 255.255.255.0
Contoh : /27 = 27 bits pertama adalah network address, 5
bits adalah host
 11111111.11111111.11111111.11100000
 255.255.255.(128+64+32+0+0+0+0+0) = 255.255.255.224

32. Subnetting
Soal  192.168.1.0 /24
-Membuat 3 buah subnet dari IP tersebut
Langkah – Langkah :
1. Gunakan rumus 2n
22 = 4  karena mendekati angka 3
/24 + 2 = /26
subnet yang akan dibuat nanti menjadi /26
subnet : 11111111 11111111 11111111 11000000
/26 = 64 host

33. Subnetting
