Chii chinonzi Subnet Mask?

A subnet mask inonziwo network mask, kero mask, kana subnetwork mask.Inotaridza kuti ndeapi mabheti ekero yeIP anozivisa subnet yemuiti uye ndeapi mabheti anozivisa bitmask yemugamuchiri.Iyo subnet mask haigone kuvapo yega.Inofanirwa kushandiswa pamwe chete neiyo IP kero.

Subnet mask ikero ye32-bit inovhara chikamu cheIP kero kusiyanisa network ID kubva kune iyo host ID, uye inoratidza kana IP kero iri paLAN kana WAN.
