Soal

Di dalam suatu jaringan perusahaan terdapat beberapa departemen bagian diantaranya :

HRD : 20 Host

FINANCE : 15 Host

IT : 12 Host

MARKETING : 25 Host

Network Address : 172.16.x.n (x adalah no absen )

Tentukan Subnetting IP ini menggunakan metode VLSM ??

Rumus = Jumlah host + host router + (broadcast +network)

Gateway = 256 - IP Total

Jawaban

Versi 2 :

Perhitungan

HRD :

20 host + 1 + 2 = 23 ==> Di Jadikan Biner 10111 = 5 (jumlah digit dari bilangan biner yang kita cari)

Subnet Mask = 11111111. 11111111. 11111111. 11100000

= 255. 255. 255. 224 --> Biner

= 8. 8. 8. 3 = 27 --> Desimal (Subnet Mask)

IP Total = 2⁵ = 32

FINANCE :

15 host + 1 + 2 = 18 ==> Di Jadikan Biner 10010 = 5

Subnet Mask = 11111111. 11111111. 11111111. 11100000

= 255. 255. 255. 224 --> Biner

= 8. 8. 8. 3 = 27 --> Desimal

IP Total = 2⁵ = 32

IT :

12 host + 1 + 2 = 15 ==> Di Jadikan Biner 1111 = 4

Subnet Mask = 11111111. 11111111. 11111111. 11110000

= 255. 255. 255. 240 --> Biner

= 8. 8. 8. 4 = 28 --> Desimal

IP Total = 2⁴ = 16

MARKETING :

25 host + 1 + 2 = 28 ==> Di Jadikan Biner 11100 = 5

Subnet Mask = 11111111. 11111111. 11111111. 11100000

= 255. 255. 255. 224 --> Biner

= 8. 8. 8. 3 = 27 --> Desimal

IP Total = 2⁵ = 32
