IP Address 192.168.1.0/29 - untuk subnet ke 30

Analisis Subnet IP Address 192.168.1.0/29

Langkah 1: Analisa

IP Address : 192.168.1.0
Kelas       : Class C
CIDR        : /29
Subnet Mask : 11111111.11111111.11111111.11111000
Decimal     : 255.255.255.248

Langkah 2: Penghitungan

1️⃣ Jumlah Subnet

Rumus: 2^x, di mana x = jumlah bit 1 yang dipinjam pada oktet terakhir.
Class C = /24, berarti pinjam 5 bit (29 - 24 = 5).
Jumlah Subnet = 2^5 = 32 subnet.

2️⃣ Jumlah Host per Subnet

Rumus: 2^y – 2, di mana y = jumlah bit 0 pada oktet terakhir.
Pada /29 → 8 bit total, 5 bit dipakai untuk subnet → sisa 3 bit host.
Jumlah Host = 2^3 – 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 setiap +8.

Subnet ke: 0, 8, 16, 24, 32, 40, 48, 56, 64, 72, … hingga 248 (total 32 subnet)

4️⃣ Alamat Host & Broadcast

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