Kalkulator Subnet IPv4
Masukkan IP dengan prefix CIDR atau subnet mask, lalu lihat network, broadcast, rentang host, dan jumlah host-nya. Bisa juga membagi jaringan menjadi subnet yang lebih kecil.

02 / tanya jawab
Seputar kalkulator ini.
Bagaimana cara memakai kalkulator subnet ini?
▼
Ketik alamat IP diikuti prefix, misalnya 192.168.1.10/24, atau diikuti subnet mask, misalnya 192.168.1.10 255.255.255.0. Tanpa prefix, kalkulator memakai /24. Klik salah satu baris di tabel untuk membagi jaringan menjadi subnet yang lebih kecil.
Kenapa jumlah host yang bisa dipakai selalu dikurangi 2?
▼
Alamat pertama dalam subnet adalah alamat network dan alamat terakhir adalah alamat broadcast, sehingga keduanya tidak bisa diberikan ke perangkat. Pengecualiannya /31 (link point-to-point, RFC 3021) dan /32 (satu alamat), yang memakai semua alamatnya.
Bisakah dipakai dari terminal?
▼
Bisa. curl 'ipku.in/alat/kalkulator-subnet-ipv4?q=192.168.1.10/24' menghasilkan hasil perhitungan dalam teks biasa.
