Mimo archaickych OS (mezi ktere se pocitaji i nedavne verze Novell Netware)
a nekterych zarizeni typu "IP stack in a toybox" (stand-alone print servery
apod.) by zadne problemy nemely nastat, classless addressing je uz preci
jen na svete peknyh par let.

Na Ciscu je potreba zapnout "ip classless" a "ip subnet-zero", ale tusim, ze
novejsi IOSy to uz maji v defaultni konfiguraci.

Ano.
