Menentukan Jumlah Host dan Subnet
Diketahui :
- 1172.6.0.0/25
- 2118.6.0.0/15
- 3 92.6.0.0/12
Tentukan :
- 1Jumlah Subnet.?
- 2Jumlsh Host/Subnet?
- 3Block Subnet
- 4 Alamat Host dan Broadcast yang valid?
Jawab
1. 172.6.0.0 /25 dengan subnet Mask := 255.255.255.128, dan
binernya : 11111111. 11111111.11111111.10000000
1. Jumlah Subnet = 29 = 512
subnet
2. Jumlah Host per Subnet = 27 – 2 =
126
3. host Blok Subnet = 256 –
128 = 128. Jadi lengkapnya adalah (0, 128)
