Subnet Mask Tsanangudzo uye Mienzaniso
A subnet mask ndiyo IP inoshandiswa -yakafanana nemazita ehukuru hwe subnetwork iyo kombiyuta kana imwe sangano rekushandisa. Ndiyo nhamba ye 32-bit iyo inoparadzanisa kero ye IP mukati mawo maviri mairi: network yekero nekheli rekugamuchira.
A subnet mask (inonziwo netmask), zvino, yakarongedzwa seizvi:
Iyo subnet mask inoumbwa nokuisa yose mitambo inobata ku1s uye kugadzirisa bits ku0s. A network inodzivirira adhesi mbiri dzisingakwanisi kugoverwa, uye izvo zvinosanganisira 0 kune kero yenethiwekhi uye 255 yeadhidhiyo yekuparidzira.
Subnet Mask Mienzaniso
Aya ndiwo mazita anoshandiswa kuChikoro A (16-bit), Kirasi B (16-bit), uye Kirasi C (24-bit) mitanho:
- Chikoro A mitambo inotsigirwa 16 777 216 mauto uye ine subnet mask ye 255.0.0.0.
- Makirasi eChikamu B ane subnet mask ye 255.255.0.0 uye inogona kuva ne 65534 IP zvigadzirwa.
- Mhuri zhinji mitambo yeChikoro C, yakasarudzwa ne subnet mask ye 255.255.255.0. Iko ukuru hwekubatanidza kunogona kusvika kune mapurogiramu ema256 IP, nzvimbo yakawanda yeimba ipi zvayo kana yebhizimisi duku.
Funga kero ye IP 128.71.216.118. Kana tikafunga kuti iri kero yeChikamu B, nhamba mbiri dzokutanga (128.71) dzinotsanangura kero yekunyoresa yeClass B apo maviri ekupedzisira (216.118) inotarisa kero yekugamuchira.
