Lab TK 2, Pertemuan 4

Assalamu alaikum Wr. Wb.

Pada kesempatan kali ini ane, ngeshare tentang bagaimana menghitung subnetting class b dan class a. Untuk pengertian subnetting bisa agan liat di post-an ane sebelumnya :). Tanpa basa - basi lagi, langsung aja gan simak di bawah ini . (*ngerti gak ngerti di telen aja gan*)

Contoh Kasus I
Diketahui :  Ip Class B
  1. Ip address     172.16.0.0/18
  2. Subnet Mask 255.255.0.0/18 
Ditanya :
  1. Subnet ?
  2. Host?
  3. Network Add/Jangkauan?
 Jawab :
Ip                      = 172.16.0.0/18
Netmask           = 255.255.0.0/18
Digit biner         = 11111111.11111111.11000000.00000000
Netmask Akhir = 255.255.192.0
*Jadi*
 
X = 2
Y =14
N = 192

*Jadi*

Subnet            = 2^X  >> 2^2 >> 4
Host               = (2^Y)-2 >> (2^14)-2 >> 16384-2 >> 16382
Network Add = 256-N >> 256-192 >> 64

*Jadi*

Subnet
172.16.0.0
172.16.64.0
172.16.128.0
172.16.192.0
Ip start
172.16.0.1
172.16.64.1
172.16.128.1
172.16.192.1
Ip end
172.16.63.254
172.16.127.254
172.16.191.254
172.16.255.254
Broadcast
172.16.63.255
172.16.127.255
172.16.191.255
172.16.255.255

Contoh Kasus II
Diketahui : Ip Class A
  1. Ip Address    = 10.0.0.0/15
  2. Subnet Mask = 255.0.0.0/15  
Ditanya :
  1. Subnet?   
  2. Host?
  3. Network Add/Jangkauan?
Jawab:

Ip                     = 10.0.0.0/15
Netmask          = 255.0.0.0/15
Digit biner        = 11111111.11111110.00000000.00000000
Netmask akhir = 255.254.0.0
*Jadi*
 
X = 7
Y = 17
N = 254

*Jadi*

Subnet = 2^X >> 2^7 >> 128
Host    = (2^Y)-2 >> (2^17)-2 >> 131072-2 >> 131070
Network add/jangkauan = 256-N >> 256-254 >> 2

*Jadi*
