Cara kerja dan rumus

Kebutuhan host diurutkan dari terbesar. Ukuran blok minimum adalah pangkat dua terdekat yang dapat menampung host + 2 alamat untuk network dan broadcast. Prefix dihitung dengan 32 − log₂(ukuran blok).

Contoh 192.168.10.0/24 dengan 100, 50, 20, dan 10 host menghasilkan blok /25, /26, /27, dan /28 tanpa overlap.
