Podsieťovanie s rovnakou maskou

Navrhnite adresovú schému pre sieť s IP adresou 68.232. 32. 0 / 20 tak, aby bolo možné mať v danej sieti 16 počítačov a čo najviac podsietí.

Sieť 68.232. 32. 0/20 musíme rozdeliť na rovnako veľké podsiete, do ktorých sa zmestí 16 PC. Pretože v každej sieti sú dve adresy, ktoré nemôžeme použiť (adresa siete a broadcastová), potrebujeme k tomuto počtu pripočítať 2 adresy a teda hľadáme sieť, v ktorej bude minimálne 16+2=18 IP adries. Pretože počítače vnímajú IP adresy v dvojkovej sústave, hľadáme najbližšiu vyššiu mocninu dvojky. K nášmu počtu hľadaných IP adries 18 je najbližšia vyššia mocnina dvojky č. 32 , čo je 2⁵. Náš prefix pre vytvorené siete bude 32-5=/27. Vytvorené siete budú mať dokopy 32 IP adries, z toho 30 bude použiteľných pre zariadenia v sieti a zvyšné 2 sú adresa siete a broadcastová adresa. Adresy jednotlivých sietí budú rásť vždy o číslo 32 .
