IP Address 192.168.1.0/29 - untuk subnet ke - 14

Analisis Subnet IP Address 192.168.1.0/29 – Versi 14 (Fokus: Subnet ke-30)

Langkah 1: Analisa

• IP Address: 192.168.1.0
• Kelas: Class C
• CIDR: /29
• Subnet Mask (biner): 11111111.11111111.11111111.11111000
• Subnet Mask (desimal): 255.255.255.248

Langkah 2: Penghitungan

1️⃣ Jumlah Subnet
Rumus: 2^x, dengan x = jumlah bit yang dipinjam.
Class C = /24 → pinjam 5 bit (29 - 24 = 5).
Jumlah Subnet = 2⁵ = 32 subnet.

2️⃣ Jumlah Host per Subnet
Rumus: 2^y – 2, dengan y = jumlah bit host (sisa 3 bit).
Jumlah Host = 2³ – 2 = 6 host per subnet.

3️⃣ Blok Subnet
Rumus: 256 – nilai oktet terakhir subnet mask.
Subnet mask = 255.255.255.248 → 256 – 248 = 8.
Artinya, subnet bertambah tiap +8 di oktet terakhir.
Subnet: 0, 8, 16, 24, 32, 40, …, hingga 248 (total 32 subnet).

4️⃣ Alamat Host & Broadcast

• Host pertama = subnet + 1
• Host terakhir = sebelum broadcast
• Broadcast = subnet berikutnya – 1
